Luís Pato, the famous Bairrada winemaker, is always doing something new. One of his recent projects is a white wine made from a rare grape called Sercialinho. This varietal was created in the 1950s by crossing two iconic grapes: Sercial, used in Madeira wine, and Alvarinho, used in vinho verde (green wine). João Pato, Luís’ father, planted this new varietal about half a century ago on the sandy soils of his Quinta de Ribeirinho. Luís always loved the grape’s aromas, which resemble those of Alsatian Rieslings. For years, he has used Sercialinho to add acidity and aroma to his renowned Vinhas Velhas (old vines). In 2013 Luís made a single-varietal Sercialinho in his father’s honor. He started producing it regularly with great results since 2019. “I’m the world’s sole producer of Sercialinho,” Luís told us with pride.

But Sogrape, Portugal’s largest wine producer, also launched to great acclaim a Sercialinho wine produced in Bairrada (in Quinta de Pedralvites). It is part of their “Séries Ímpares” created to showcase unique varietals and terroirs. 

DNA analysis revealed that Sogrape’s Sercialinho is a cross of Vital and Uva Cão. Is this the same varietal that João Pato planted? Are the two Sercialinhos identical twins, fraternal twins, or homonymous strangers? It is a mystery. What we do know is that they’re both spectacular wines!
