How humans made the soil of the Douro Valley

~ saltofportugal ~ 1 Comment

This is the second lecture about the Douro Valley by the great viticulturist António Magalhães. Today’s theme goes literally beneath the surface. After exploring the climate in our first session, we turn to the second pillar of the region’s terroir: its soil.

A Soil Made by Hand

When you walk through a vineyard in the Douro Valley, take a moment to look down. You see the slow artistry of nature, which over millions of years created the schist beneath your feet, and the tireless toil of generations who transformed it into living soil where vines can thrive.

The Douro’s deep valleys were carved over millennia by the river and its tributaries. On those steep slopes, the native soils, known as leptosols, are little more than a palm’s depth of earth resting on hard schist. Left untouched, they would never have sustained flourishing vines.

But in the Douro, people refused to accept nature’s limits. Over the course of centuries, they created anthrosols — soils made by human hands. The locals call the act saibrar, agronomists surribar: it means breaking rock to create soil where vineyards can grow.

The photograph shows that the schist bedrock appears brittle and easily broken. Above it lies the soil created by human labor. Look closely, and you can see the vine roots reaching down, searching for that last drop of water that keeps them alive through the scorching summer heat.

The image illustrates the words of the Marquis of Villa Maior, from his 1875 treatise, Practical Viticulture:

“The longevity of the Douro and Burgundy vines is due to the extraordinary development of their roots, favored by the nature of the subsoil.”

Breaking Rock to Grow Life

Until the late 19th century, surribar was done with nothing more than pickaxes and iron bars. In the 20th century, dynamite was introduced, followed later by bulldozers and hydraulic excavators. Yet the goal remained the same: to give each vine at least a meter and a half of soil depth.

The schist fractures almost vertically, allowing roots to slip deep between its plates. There, the vine finds not abundance but balance: less than 1.5 percent organic matter, yet perfectly aerated and rich in minerals. These fractured layers also ensure excellent drainage, carrying away excess rainwater while retaining just enough moisture for the vines to endure the long dry season. It is a poor soil that yields noble fruit, a reminder that in wine, perhaps as in life, struggle builds character.

Stones and Gravel

Kneel in a Douro vineyard and you’ll see a glittering mosaic of crushed stone and gravel. To outsiders, it looks barren; to the vines, it’s paradise.

In 1947, agronomist Álvaro Moreira da Fonseca, who devised the Douro’s vineyard classification, ranked soils by their gravel content. His creed, simple and enduring, can be expressed in words worthy of being carved in stone: “Vines thrive on stony ground.”

The gravel plays alchemy with the elements: reflecting sunlight by day, releasing heat by night, regulating the vine’s rhythm. It stores warmth, tempers vigor, and transforms scarcity into intensity.

Counting by the Thousands

António says that “The poorer the soil, the closer the vines.” Douro farmers compensate for the soil’s low fertility by planting vines at higher densities. Each vine produces modestly, but together they create abundance. Instead of counting hectares, growers speak of milheiros — groups of a thousand vines.

After the phylloxera epidemic, the rebuilt terraces — socalcos — reached a density of 6.5 milheiros per hectare, enough to make every meter of stone wall worthwhile. 

Sculpting the Mountain

Rain, the same force that helped carve the Douro, also threatens to destroy it. The solution lies in building terraces to prevent soil from sliding away. During the surriba, the stones brought to the surface are removed and reused to build the vineyard walls. This operation, called despedrega, is a practice that makes the back-breaking labor of surribar more rewarding.

Some of the terraces devastated by phylloxera were never replanted. Many owners, overcome with despair, abandoned the region to rebuild their lives elsewhere. Others chose to start anew, replanting vines on gentler slopes with more forgiving soils and milder climates. 

These abandoned terraces, known as mortórios, have been reclaimed by the Mediterranean forest. Their stone walls, now entwined with wild vegetation, stand as silent witnesses to a tragic chapter in the Douro’s history.

The oldest terraces, built after phylloxera, were supported by dry-stone walls, feats of balance and beauty where each stone rests “one upon two.” In the 1960s, as labor became scarce and tractors arrived, new earth-banked terraces (patamares), depicted below, took their place — practical but less graceful.

At the turn of this century, António Magalhães and David Guimaraens, the head winemaker of Taylor’s Fladgate, combined the beauty of the old dry-stone terraces with the practicality of the modern earth-banked ones. Inspired by California’s Benziger Family Winery, they built narrow terraces, just 1.5 meters wide, each with a single vine row and a gentle 3 percent slope to drain rainwater safely. Precision-leveled by laser, this innovation protects against erosion while preserving the Douro’s graceful geometry. 

Root and Rock

The phylloxera plague that ravaged European vineyards in the late nineteenth century arrived at the Douro in 1863-64.

Salvation only came after Jules-Émile Planchon, a French botanist, and Charles Valentine Riley, an American entomologist, discovered that grafting European grapevines (Vitis vinifera) onto American rootstocks could save the vines. 

One such rootstock, Rupestris du Lot, thrived on the Douro’s poor, dry, schistous hillsides.

It seems to facilitate potassium absorption. This mineral helps regulate the opening and closing of tiny pores on leaves, called stomata, which control transpiration and CO₂ uptake — both essential to photosynthesis.

For decades, the Rupestris du Lot anchored the valley’s post-phylloxera vineyards, its deep-seeking roots echoing the surriba’s purpose: to connect life to stone. Even as newer, more productive hybrids replaced it, António continues to praise its quiet virtues — longevity, restraint, and resilience — the very qualities that define the Douro itself.

Granite Lagares

The granite lagares of the Douro are among the most enduring symbols of the region’s winemaking heritage. Their coarse surfaces help regulate temperature during fermentation and impart a tactile connection to the land — the sensation of grape skins and must mingling with the mineral essence of granite itself.

For centuries, blocks of rock were quarried from places like Vila Pouca de Aguiar, Portugal’s self-proclaimed “granite capital,” where the stone’s density allows it to be cut into large rectangular slabs. 

António concludes his lecture with poetic words: “In the Douro where I grew up, the grapes journey from rock to rock — ripening in the heat of schist and fermenting in cool granite lagares.”

What to Visit

The train trip from Pinhão to Pocinho offers a geology lesson. Along the slopes that flank the railway, you see the leptosol with its thin layer of soil above the parent rock.

The art of building dry stone walls is beautifully explained at the Wine Museum in São João da Pesqueira, a town whose historic center also deserves exploration. The visit whets the appetite for lunch at Toca da Raposa, in Ervedosa do Douro, about 8 kilometers away along the National Road 222, heading toward the mouth of the Torto River — another magical tributary that shapes the wines of the Douro, alongside the Pinhão River. In the summer, you can also book an unforgettable picnic at the Foz Torto estate with our friend Abílio Tavares da Silva.

António recommends reading “Taste the Limestone: A Geologist Wanders Through the World of Wine,” by Alex Maltman. You’ll return home with a deeper understanding of soils and their decisive role in defining terroirs across the world.

A journey through the Douro’s three Regions with António Magalhães

~ saltofportugal ~ 6 Comments

António Magalhães, former chief viticulturist of Taylor Fladgate, is revered throughout the Douro for his deep knowledge of its vineyards and terroir. He graciously agreed to give us a series of master classes about the Douro, and what follows are notes from the first of these sessions—an insider’s look at one of the world’s most extraordinary wine regions.

About António

António was born in Régua, in the heart of the Douro. Both of his parents came from families who cared for their own vineyards. He often spent time at his maternal grandfather’s estate, where his love for the Douro was first nurtured. Although he never inherited land, his studies were guided by a single calling: to work among the vines of his native valley.

A Land of Mountains and Microclimates

The Douro is immense — 250,000 hectares of rugged mountains, of which only 44,000 are occupied by vineyards. It is the largest mountain viticulture region in the world, and the only one with a Mediterranean climate crossed by a navigable river that flows into the Atlantic Ocean.

The basin of the Douro, the largest in the Iberian Peninsula, is shared by Portugal and Spain. Its main river and tributaries flow through a tapestry of vineyards across wine regions: Ribera del Duero, Rueda, Cigales, Toro, and Arribes, in Spain, Douro and Távora-Varosa in Portugal. You could say that the Douro is a river of wine.

The Douro’s rise as a great wine region began in 1703, when Portugal signed the Methuen Treaty with England, opening trade between the two nations. Douro’s Port wine became popular in England, and demand soared. Vineyards spread, and some producers began to cut corners—darkening their wines with elderberry juice and sweetening them with sugar. Port’s reputation faltered, and trust among English importers began to erode.

To restore order, avoid the use of fertile land for viticulture, and protect Port’s reputation, the Marquis of Pombal created the world’s first demarcated wine region in 1756. The Companhia Geral da Agricultura das Vinhas do Alto Douro, a public company, marked its boundaries with granite pillars known as marcos pombalinos and classified its vineyards. The finest plots produced the prized vinhos de feitoria, destined for the great British trading houses (feitorias) in Porto. Wines of intermediate quality, the vinhos de embarque, were partly exported, while the more modest vinhos de ramo were reserved for local consumption. With this demarcation, a singular landscape was born, shaped by nature’s hand and human will.

It was fortuitous that there was open land in Gaia, near Porto, on the southern bank at the mouth of the Douro. There, the north-facing slopes and the cooler, more humid weather provided ideal conditions for storing and aging wine. With its quality safeguarded and easy access to an Atlantic port from which ships could carry it abroad, Port wine flourished, becoming prized around the world.

The Douro River flows west to meet the Atlantic at Porto (Álvaro Moreira da Fonseca (1944–45)).

The climate and regions of the Douro

On what António calls the “Olympic podium” of terroir, climate wins gold, soil takes silver, and grape varieties bronze. Today, we focus on climate.

Vines don’t need irrigation, but they do require at least 500 mm of rainfall per year. In the Douro, however, the irregular rainfall and rapid runoff down the steep slopes increase that need to about 600–700 mm. The timing of that rain is crucial. It rains about as much in Pinhão, at the center of the Douro, as in Paris—around 640 mm annually. However, in the capital of France, rain falls throughout the year, whereas in the Douro, the rain is in tune with the vines’ vegetative cycle: it falls mainly in autumn and winter, when the vines are dormant. Planted in the right places, Douro vineyards never suffer from thirst, only from heat.

The distribution of rainfall divides the Douro into three distinct subregions. Baixo Corgo is lush and green, blessed with 800 to 1,000 mm of rain each year. Cima Corgo, home to the great Port houses, is drier, with 600 and 800 mm. Farther east lies Douro Superior — sun-scorched, rugged, and remote, where rainfall often falls below 600 mm.

Rainfall in the Douro: blue = high, yellow = medium, orange = low.

Vineyards are abundant in Baixo Corgo and sparse in Douro Superior, where cultivation is possible only in small islands with favorable microclimates. In recent decades, irrigated vines have appeared in Douro Superior, yet they rarely produce grapes suitable for making Port.

The scholar Alfredo Guerra Tenreiro wrote that “there is a uniqueness in the Douro climate that one can feel in the uniqueness of Port wine.” In the 1940s and 1950s, he mapped the aridity of the Douro using a simple measure: average temperature multiplied by 100, divided by rainfall. As one moves west or climbs the surrounding hills, aridity decreases because the temperature falls and rainfall increases. 

As we ascend the hills that flank the Douro and its tributaries, the temperature drops roughly 0.65°C per 100 meters. With peaks rising to 600 or 700 meters, temperatures can be as much as 3.6°C cooler than in vineyards planted near the river, at 100 meters of altitude.

Orientation also matters. South-facing slopes are, on average, two degrees warmer than north-facing ones during the summer — a subtle difference with dramatic effects. It explains why the Douro can yield everything from festive sparkling wines, such as Celso Pereira’s Vértice, to bright whites, velvety reds, and opulent Ports.

Álvaro Moreira da Fonseca used location, altitude, and orientation to craft his brilliant classification of the region’s vineyards, grading them from A to F. This system still underpins the benefício rules that determine how much of a vineyard’s production can be used for Port wine. His maps, drawn in 1944 and 1945, are masterpieces. Fonseca set 500 meters as the upper limit for Port production, deducting points for vineyards planted above that line.

Map by Álvaro Moreira da Fonseca (1944–45). Red marks top wine areas.

Looking at Fonseca’s maps, we see a “blessed valley” — Vale de Mendiz, where the Pinhão River meets the Douro. There, rainfall from the Baixo Corgo meets the warmth of the Cima Corgo, producing wines of exceptional balance. It is no coincidence that iconic estates like Quinta do Noval and Wine & Soul call Vale de Mendiz home.

Traveling Through the Douro

António recommends visiting the Douro between mid-May and mid-November, staying for several days to ensure you catch a sunny spell. Gray skies hide some of the valley’s splendor.

He suggests two journeys for those eager to understand the Douro.

First, drive along the A24 highway from Vila Real to Régua, crossing the Marão mountain — an invisible wall separating cool Atlantic air from the dry Mediterranean hinterland. You’ll cross the Baixo Corgo moving perpendicular to the course of the Douro River. The landscape is breathtaking, and along the way you can feel the shifts in temperature and altitude that shape the character of Douro wines. 

Begin in Vila Real at 450 meters of altitude, and as you descend toward Régua, at 100 meters, feel the temperature rise and watch the hills unfold into a sea of vines. Olive trees stand like sentinels at the edges of vineyards. Climb toward Lamego, at 540 meters, and feel the air cool once more. The whitewashed houses, stone wine lodges, and hillside villages lend a human touch to the landscape, making the journey unforgettable.

In Régua, stop at Aneto, a small, family-run restaurant where hospitality flows as generously as the wine produced in their own estate. In Lamego, stop at Pastelaria Velha da Sé for a bola de carne (savory meat-filled bread), visit the cathedral, the Escadório de Nossa Senhora dos Remédios, a Baroque stairway, and admire the Ribeiro da Conceição theater, a miniature La Scala.

The second journey is by train, linking three UNESCO World Heritage sites: Porto, the Douro, and the Côa Museum, which preserves paleolithic art.

The hills were carved to lay the train tracks, turning the voyage into a geology lesson on Douro’s mother rock, the schist. Its cleavage is almost vertical, allowing the vine roots to penetrate deeply into the cracks in search of precious water.

As the train leaves Régua, schist terraces rise and curve around the river. Disembark at Pinhão and linger a few days visiting nearby wine estates. Before you go, admire the station’s twenty-four azulejo panels, made in 1937 by the Aleluia Factory in Aveiro. They depict the Douro landscape and trace the making of Port—from the harvest of sun-ripened grapes to the voyage of slender rabelo boats, which carry barrels to the cellars of Vila Nova de Gaia.

Continue upriver through the Cima Corgo, the heartland of Port. In bygone days, train-station restaurants were famed for their quality. Calça Curta, at Tua Station, keeps this tradition alive. Farther along, stop at Ferradosa Station to dine at Toca da Raposa, celebrated for its regional cooking. 

As the train enters the Douro Superior, the air turns drier, the heat more intense, the hills steeper. At Cachão da Valeira, the landscape shifts to granite. Today, the river glides wide and serene, but it once raged against a massive granite barrier that made navigation perilous. Here, in 1861, tragedy struck: a boat capsized carrying two iconic figures—Dona Antónia Ferreira, owner of vast wine estates, and the Baron of Forrester, an English merchant and mapmaker who devoted his life to the region. According to legend, Dona Antónia survived, buoyed by her billowing skirts, while the Baron drowned, dragged down by the gold coins in his pockets. 

In summer, cicadas sing for travelers along the stretch between the Valeira gorge and Pocinho. As you near Pocinho, the heat intensifies—writer Francisco José Viegas once quipped that “hell’s heat comes from Pocinho.” Stop at Taberna da Julinha, a local restaurant that, in the summer, serves the valley’s celebrated tomatoes, bursting with flavor and sweetness.

The Côa Museum lies about 10 kilometers from the train station. There, you can contemplate the largest and oldest ensemble of open-air Paleolithic engravings in Europe. Horses, deer, and goats emerge from the stone, their lines layered in a dance of timeless motion. Dine on the museum’s terrace, overlooking the river laid bare in all its austere beauty—terraces and cliffs carved by nature and human will.

The Future of the Douro

The Douro was forged in hardship. Its people labored to carve terraces from unforgiving slopes; its vines learned to endure searing summers and biting winter frosts. Yet this endurance may be the valley’s greatest gift. It has prepared the Douro to face the trials of a changing world.

Maria Doroteia’s famous Douro biscuits

~ saltofportugal ~ 1 Comment

Jorge Seródio Borges and Sandra Tavares da Silva, the husband-and-wife team behind Wine & Soul, craft some of the Douro Valley’s most iconic wines—among them the extraordinary Guru, Pintas, and Manoella Vinhas Velhas. Jorge’s roots in the valley run deep: his family has been making wine there for five generations.

His mother, Maria Doroteia, devoted her life to teaching the children of the Douro Valley how to read and write. She also has a deep love for animals; at 87 years of age, she still tends to ten hens, who reward her with fresh eggs.

Maria Doroteia is renowned for her cooking. When Jorge and his sister were little, she would bake biscuits and hide them away in tins. As soon as the children caught the first whiff of the delicious aromas, they would set off on a treasure hunt until they found the precious trove of cookies, savoring them with delight.

We recently had the joy of having lunch with Maria Doroteia. With her characteristic generosity, she shared one of her cherished recipes, which we are happy to pass on to you, dear reader.

Eduardo Cardeal’s great challenge

~ saltofportugal ~ Leave a comment

Eduardo Cardeal was born in Abaços, a small village in the Douro Valley, where he learned the art of winemaking from his grandfather. As a child, he absorbed the traditions without fully understanding them. His grandfather used to say that the wine wasn’t “cooked” until April. Years later, while studying enology in college, he realized this phrase referred to the malolactic fermentation, the natural process through which lactic acid bacteria transform tart malic acid into softer lactic acid, reducing acidity, enhancing texture, and adding complexity to the wine.

We first met Eduardo in 2019, when he was the head enologist at Herdade da Calada. His life had been marked by tragedy—his wife had passed away, and he found himself raising their three young daughters alone. Seeking a fresh start, he returned to his roots in the Douro Valley and purchased Quinta da Peónia, a historic one-hectare vineyard planted in 1930. It is an estate with a human scale, allowing Eduardo, with the help of his daughters, to handle every step of production—from grafting vines to foot-treading grapes and bottling the wines.

He named this deeply personal project Grande Desafio, meaning “great challenge.” His goal is to create the ultimate handcrafted wines. In 2023, after years of dedication, Eduardo bottled his first vintage—5,000 precious bottles.

Perched on a plateau 550 meters above sea level, Quinta da Peónia is blessed with schist and clay soils. Unlike the famed, fast-draining schist of Foz Côa, Peónia’s porous schist retains water through the winter, naturally sustaining the vines during the dry summer months without irrigation. The altitude brings freshness, while the old vines add remarkable depth and complexity.

Eduardo’s winemaking philosophy focuses on low alcohol and minimal extraction, resulting in light, elegant wines that dance on the palate with remarkable finesse. These wines are rare finds—if you come across a bottle, take it home and treasure it.

Alheiras

~ saltofportugal ~ 2 Comments

The origin of alheiras (pronounced ahl-yay-ras), a traditional Portuguese sausage, is intertwined with the history of Portugal’s Jewish community during the reign of King Dom Manuel I (1495–1521). 

Dom Manuel sought to strengthen Portugal’s standing in Europe by marrying the daughter of the Spanish Catholic Monarchs, Ferdinand of Aragon and Isabella of Castile. However, the union came with a condition: Portugal had to adopt Spain’s policies toward Jews, forcing them to either convert to Christianity and become “New Christians” or leave the country.

Jewish dietary laws forbid the consumption of pork, a staple of Portuguese cuisine. To avoid persecution, New Christians ingeniously created a pork-free sausage using bread, garlic, and other meats such as poultry or game. These sausages, known as alheiras (from alho, the Portuguese word for garlic), were smoked to resemble traditional pork sausages, allowing Jewish families to appear to conform to local customs.

Today, alheiras are a cherished element of Portuguese cuisine, particularly in the Trás-os-Montes region, where they originated. The town of Mirandela is especially famous for its alheiras. Although modern recipes often include pork, these sausages stand out for their distinctive flavor.

Preparing alheiras is far more complex than making traditional chouriços. To make chouriços, pork is marinated in vinha d’alhos—a flavorful blend of garlic, bay leaf, salt, olive oil, paprika, and wine—before being stuffed into casings and smoked until dry. In contrast, alheiras require meticulous preparation: a variety of meats are carefully cooked and then combined with bread and spices before filling the casings and smoking the sausages. Every detail is crucial in this labor-intensive process.

The finest alheiras we’ve ever tasted are crafted by Maria da Graça Gomes and her daughter, Rosário Buia, at Toca da Raposa in the Douro Valley. They are made with an exquisite mix of meats, including rabbit and pheasant, and seasoned with great finesse. Grilled, lightly fried in olive oil, or baked in the oven, these sausages are a culinary feast.

Toca da Raposa makes alheiras between November and January. You can place an order by calling 969951191.

Finding perfection at Ervamoira

~ saltofportugal ~ 4 Comments

“When my father came home from work, he would spend hours studying military maps,” recalls Jorge Rosas, the CEO of Ramos Pinto, a port wine house founded in 1880 by his great-grandfather, Adriano Ramos Pinto. “He was searching for the perfect farm in the Douro Superior, a region he believed could produce exceptional wines like the legendary Barca Velha.”

Sitting on the floor with an old magnifying glass that had lost its handle, Jorge’s father, José António, pored over contour lines in search of flat land. He wanted to find terrain that was easier to cultivate than the steep slopes that dominate the Douro Valley. From Friday to Sunday, José António drove through rustic roads, to visit locations he had marked on the maps.

One day, crossing a remote mountain path, he found his dream farm. “Shangri-La!” he exclaimed. The estate, then planted with cereals, was called Ervamoira. It was love at first sight—a love so strong that his wife often felt jealous of the farm. Determined to buy it, José António contacted the owners in Lisbon. Despite having little attachment to the estate, they hesitated to sell a property that had been in their family for generations.

An avid trout fisherman, José António donned his fishing gear to fish in the rivers that cross Ervamoira, the Coa, and the Douro, even though he knew they had no trouts. Fishing was merely an excuse to immerse himself in the landscape, imagining the vineyards he might one day plant.

In the aftermath of the 1974 revolution, many farms were nationalized. Fearing expropriation, the owners of Ervamoira agreed to sell. Despite his family’s concerns about buying an estate amid so much uncertainty, José António seized the opportunity. “My father is a cereal killer,” jokes Jorge, alluding to how the cereal fields were soon replaced with vineyards.

At Ervamoira, José António introduced innovative viticultural practices. He assigned each grape varietal to a separate plot. Instead of using traditional terraces, he planted vines on platforms that facilitate mechanization. High-density planting forced roots to delve deep for nutrients, enhancing quality through higher polyphenol content and increasing drought resistance.

But a shadow loomed over paradise. In the early 1990s, plans resurfaced to construct a hydroelectric dam that would flood the estate. Horrified, José António fought tirelessly against this project. The discovery of a Roman tomb and ancient coins on the property provided fleeting hope, but archaeologists deemed the finds insufficient to halt the dam project.

Desperate, José António entered his wines into international competitions, receiving numerous awards. But not even these accolades could stop the project.  “What now?” he wondered. “Only a miracle can save the farm,” his cousin, João Nicolau de Almeida, remarked.

Then, a miracle happened. Archaeologists discovered prehistoric cave engravings near Ervamoira.  An expert who secretly evaluated the site revealed that the engravings are about 30,000 years old. It was widely assumed that outdoor prehistoric art couldn’t survive millennia of exposure to the elements. Ervamoira proved otherwise.

The discovery attracted the attention of the Portuguese media but failed to sway the government. Deliverance came from an unexpected source. A Portuguese émigré, who had been Jacqueline Kennedy’s butler, read about the engravings in a local newspaper. He shared the news with an acquaintance at The New York Times, and the newspaper published an article titled “Vast Stone Age Art Gallery Is Found but Dam May Flood It.” The story sparked an international outcry that led to the abandonment of the dam project.

Today, Ervamoira thrives. Its grapes contribute to the iconic Duas Quintas wines, made from a blend of grapes from two farms—Ervamoira and Bons Ares. The schist soils of Ervamoira, at 150 meters altitude, lend structure, while Bons Ares, perched at 550 meters with limestone soils, adds refreshing acidity.

Ervamoira’s magic is unmistakable. Nestled in the remote Douro Superior beyond the Cachão da Valeira—a region inaccessible until Queen Maria I spearheaded efforts to make the Douro River navigable—it is a gem of the Douro Valley, a dream that a miracle made come true.

The Douro Heirloom Tomato Festival

~ saltofportugal ~ Leave a comment

The tomato is a South American fruit that traveled to Europe on sailboats in the 16th century and, over time, conquered the cuisines of the Old World. Like travelers who adapt to foreign lands, tomatoes developed distinct characteristics in different regions. In the Douro Valley, the warm days, cool nights, well-drained soils, and abundant micronutrients produce tomatoes with exceptional flavor, texture, and succulence. 

Every year, on the third Friday of August, the Douro Valley comes alive with a festival dedicated to the heirloom tomato. Winemakers submit tomatoes grown in their vegetable gardens to this friendly competition, an opportunity to enjoy some light-hearted fun before the serious work of the harvest begins. Renowned chefs like Miguel Castro e Silva prepare the food and vintners pour their wines, creating a festive atmosphere.

The tomatoes are served at peak ripeness, blessed with a pinch of Castro Marim sea salt, and anointed with sacred olive oils from the Douro Valley. A panel of judges, composed of chefs and food experts, conducts a rigorous blind tasting to elect the finest tomatoes.

This year, a small producer, Casa da Quinta dos Ferreiros took first place. Wine & Soul, acclaimed for their iconic Pintas and Guru wines, received second place. Third place was awarded to the Mateus Palace.

The festival was conceived by Abílio Tavares da Silva, the charismatic Foz Torto winemaker, Celeste Pereira, a gifted communications strategist, and Edgardo Pacheco, a renowned food journalist.

Each year, a different winery hosts the festival. Previous editions were held at Quinta de la Rosa, Quinta do Vallado, Quinta de Ventozelo, Niepoort’s Quinta de Nápoles, and Sogrape’s Quinta do Seixo. This year’s event took place at the Mateus Palace, a graceful Baroque manor surrounded by serene gardens.

The festival is open to the public. If you dream of mingling with famous chefs and winemakers at a picturesque Douro Valley estate, mark your calendar for the third Friday of August. You can email greengrape@greengrape.pt to join the mailing list. One word of advice: once you receive your invitation in late July, answer immediately—the event sells out in less than an hour!

António Magalhães, keeper of Douro secrets

~ saltofportugal ~ 6 Comments

You might not be familiar with António Magalhães, the chief viticulturist of the famed Taylor-Fladgate port house, but if you enjoy exceptional port wines, you’ve likely experienced the fruits of his labor. António has worked for more than three decades in the rolling terraces of the Douro Valley. Throughout this time, nature has gradually revealed to him some of its winemaking secrets. Patience has been essential in this apprenticeship. It can take many years to grasp the impact of viticulture choices on wine production.

António is known for his thoughtful character and gentle disposition. But beneath this demeanor lies a powerful intellect–he has the rigor of a scientist, the curiosity of a historian, and the eloquence of a poet. He believes in combining scientific methods with traditional wisdom and has a deep reverence for the mysteries of winemaking. 

In collaboration with a statistician, António sought to unravel some of these mysteries, analyzing climate data since 1941 to identify weather patterns associated with vintage years, the finest for port wine production. They discovered that these years share three characteristics. First, the average temperature in July is less than 24.5 degrees Celsius. Second, two-thirds of the rain falls during the dormancy period (from November to February) and one-third during the growth period (from March to June). Third, there is less than 20 millimeters of rain in September. A small amount of rain at harvest time helps refine the grapes, says António, but too much rain in September fills the grapes with water and promotes fungal diseases. To António’s delight, they found that exceptional vintage years often deviate from the norm in unique ways, a testament to the magic of port wine.

Another facet of this magic is the art of blending. The Douro’s diverse microclimates provide winemakers with a rich palette to adapt to the annual variations in weather. They skillfully blend diverse varietals from vineyards with different locations, altitudes, and sun exposure. António has a profound understanding of the art of blending grounded on his comprehensive knowledge of the Douro subregions—the rain-soaked Baixo Corgo, the moderately wet Cima Corgo, and the arid Douro Superior. 

He has studied how grape varietals were adapted to counter the crisis created by phylloxera, an American insect that decimated European vines in the second half of the 19th century. The blight reached the Douro region in 1862-63 and became a severe problem in 1872. Farmers noticed that Mourisco, a varietal with lackluster enological properties, was the most resistant to phylloxera. For this reason, Mourisco was crossed with Touriga Nacional, considered the finest pre-phylloxera varietal, to create Touriga Francesa. The name, which means French Touriga, was likely chosen to honor the French school of viticulture and its contribution to creating phylloxera-resistant varietals. 

António also analyzed the various types of American vine roots brought from places like Texas to the Douro Valley to graft European vines and increase their resilience to phylloxera.

Since 1992, António has worked closely with David Guimaraens, the chief enologist at Taylor-Fladgate. Every year, António and David write several letters to the farmers who produce grapes for Taylor-Fladgate, offering insights into the vines’ current conditions and the most effective viticulture practices to respond to them. This educational effort is vital to the quality of the Taylor-Fladgate ports.

Concerned with the impact of heavy rainfall on soil erosion, António and David developed a new model for the terraces where the vines are planted. They had an epiphany while visiting the Benziger family, a biodynamic wine producer in California. It started to rain torrentially, and as they ran for shelter, they noticed that the rain was running with them. They realized that this kind of drainage, created by a three percent gradient, is what the Douro Valley needs.

António and David asked earthmoving companies to find a bulldozer narrow enough to fit in the terraces and capable of creating a three percent inclination. One of the companies found a second-hand machine used in rice plantations in the south of Portugal. The company’s manager called to say that the machine had an unusual device. “Bring it along,” said António. It turned out that the device was a laser that greatly simplified the task of creating a three percent slope. They later learned that the Benziger farmland had been graded by Chinese workers, who were likely to be familiar with the three percent inclination used in rice cultivation.

The Taylor-Fladgate farms stand out for their beauty because António is a sculptor of landscapes. He knows that cultivating a vineyard, planting a tree, or building a stone wall alters the scenery, and like an artist, he selects colors that harmonize, proportions that feel human, rhythms that please the eye.

António is passionate about researching the history of the Douro region. He often visits Torre do Tombo, a vast national archive with documents spanning nine centuries of Portuguese history. The writings of Álvaro Moreira da Fonseca (the creator of the vine quality scoring system still in use), the Baron of Fladgate, John Croft, José Costa Lima, A. Guerra Tenreiro, and many other Douro luminaries are his constant companions.

His extensive knowledge of history gives him a unique appreciation for the sacrifices made by generations of workers who have toiled in the Douro region. This understanding is evident in how António interacts with the people he manages. His sincere appreciation for their efforts earns him the loyalty and trust of his collaborators.

Today, António Magalhães retires as Taylor-Fladgate’s chief viticulturist. This milestone marks the beginning of a new chapter. We hope that António can now find the time to write a treatise on viticulture so that, as the climate continues to change, his erudition can illuminate the future of the Douro Valley.

A perfect picnic

~ saltofportugal ~ 1 Comment

Victorian novels describe picnics where friends have a grand time, enjoying delicious food in idyllic settings. But real-life picnics seldom measure up to these literary accounts. Sometimes, the sun is too harsh, and the shade is scarce. Other times, it is cold, the wind blows disagreeably, or the rain intrudes. Wine and beer are lukewarm by the time they are served. Sitting is uncomfortable, and troupes of insects join the party.

When our friend Abílio Tavares da Silva invited us for a picnic, we braced ourselves for the usual woes. But, as soon as we arrived at his Douro Valley estate, it was clear that this would be no ordinary affair.

It was a midsummer day with clear skies and a gentle breeze. Spacious wooden tables with comfortable benches awaited the lucky guests under the shade of two majestic linden trees. The view, with the Douro River stretching out in all its splendor, was worthy of being painted by Turner.

The picnic basket, prepared by the talented Rosário Buia at Toca da Raposa, was brimming with delicacies. There were farinheira tarts, shrimp rissoles, oranges seasoned with olive oil and minced garlic, chickpea salad, carrot and zucchini rice, olives, freshly baked bread, and a tortilla prepared with eggs so delicious that they were surely laid by the happiest of chicken.

The food was served in colorful pottery designed by the 19th-century master ceramist Rafael Bordallo Pinheiro. Abílio’s alluring Foz Torto white wine, made from precious old vines in Porrais, was poured into crystal glasses at the ideal temperature. 

The conversation flowed as freely as the food and the wine. The meal ended late in the afternoon with slices of Toca da Raposa’s famous drunken cake (bolo borrachão) accompanied by glasses of chilled 20-year-old Fonseca tawny port. Not even Jane Austen could imagine such a perfect picnic.

Quinta do Vale Meão

One of the Douro Valley’s ultimate experiences is visiting Quinta do Vale Meão. While the estate is not generally open to the public, it does receive a few small groups each year. You can email in advance to inquire whether they can host you.

Vale Meão was the last estate planted by the legendary Dona Antónia Ferreira. It was a colossal endeavor: 300 hectares of wild bush were converted into vineyards and olive groves. Dona Antónia invested in the remote Vale Meão against the advice of her general manager because of its unique characteristics. It is located on a geological fault with three different types of soil: schist, granite, and sedimentary clay deposited by the river. The weather is dry, as clouds rarely cross the Marvão mountain, reducing the prevalence of vine diseases like oidium.

The best way to reach Vale Meão is by taking the train from Pinhão to Pocinho. There are usually few passengers, so you can choose a seat by the riverside and enjoy a glorious hour beholding the Douro river in all its splendor. The train rushes through bridges and tunnels carved into granite hills, but the river is seldom out of sight.

You go by Cachão da Valeira, a treacherous spot before dams regulated the water flow. Here, Dona Antónia and the Baron of Forrester, another eminent figure of the Douro Valley, fell into the river in a boating accident. Dona Antónia survived, but the Baron drowned. The locals say in jest that her voluminous skirt saved her, while the Baron sank because his pockets were filled with gold coins.

Maria Ferreira, a former teacher who oversees enotourism at Vale Meão, picked us up at the Pocinho train station in a vintage Land Rover. Though not related to Dona Antónia, Maria speaks about the estate with such passion it feels as though she is part of the family. An eagle followed the Land Rover as we drove through Cortes de Veiga, a village created to house the many laborers who worked at Vale Meão between 1885 and 1887.

The name Meão, which means “middle,” refers to the river encircling the property, making it feel like an island. The vineyards are planted on a magnificent plateau by the river.

Maria took us on an exhilarating safari through the vineyards. We then visited Barca Velha, a cellar built in 1892 named after an old rowboat used to cross the river. Here, Fernando Nicolau d’Almeida crafted the first Barca Velha in 1952, combining grapes from Vale Meão with those grown at higher altitudes in Meda to craft a table wine that became iconic.

Our tour concluded at the main house, constructed by Dona Antónia in 1894. We were warmly received by three of her descendants: Francisco Olazabal, known as Vito, his son Francisco, known as Xito, and his daughter Luísa. They welcomed us with a refreshing white Monte Meão, made from a blend of two grape varietals grown at opposite ends of the estate—Arinto in the sedimentary soils of the north and Rabigato in the schist soils of the south. This wine beautifully showcases the diversity of the terroirs at Vale Meão.

As we talked to Vito, Xito, and Luísa, it became clear that wine is a language to them. Soils and grape varietals are like words that can express human craftsmanship and the whims of the seasons to make wine as fine as poetry. Their passion for wine is only matched by the generosity with which they share the fruits of this extraordinary place with those who visit.

We tasted the Monte Meão Vinha da Cantina, a surprising wine made from baga, a red grape from Bairrada. While in Bairrada, baga produces tannic, robust reds; here, it yields a light (11.5% alcohol), vibrant wine.

Next, we enjoyed a remarkable Monte Meão Touriga Nacional from the granite soils of Vinha dos Novos. It has a crimson color, a delicate floral aroma, and a supine elegance on the palate. It was followed by a beautiful Monte Meão from Casa das Máquinas, home to the estate’s oldest vineyards that combines Touriga Francesa and Tinta Barroca.

The tasting of table wines concluded with two stunning Vale Meão vintages. The 2014 vintage is a complex, alluring wine, and the 2002 vintage is exquisite in its subtlety and refinement. 

Then, port wines entered the scene. First, a 10-year-old tawny, which is all that a great tawny can be, offering notes of nuts, coffee, chocolate, and orange rind to enchant the palate. Then, a stunning 1999 colheita, that is richly satisfying.

In 1999, Vito took a significant risk by leaving his safe position as a director at Sogrape, the large wine company that acquired most of Dona Antónia’s properties, to start a new family project under the Vale Meão name. The many accolades earned since then, including inclusion in the Wine Spectator’s list of the world’s top 5 wines, show clearly that the risk paid off. From her celestial vantage point, Dona Antónia must be beaming with pride.
