Time is a great equalizer of port wines. Tawnies are red ports aged for many years in large barrels made from oak and chestnut wood. These wines mellow with age, trading the red colors and brash tannins of their youth for discreet amber hues and complex flavors.
White ports can be frivolous when young. But, as they age, they gain depth and character. After about three decades, whites and reds retain different flavors and aromas but they agree to wear the same colors.
Old tawnies are rare pleasures. But old white ports, like the magnificent 1963 Dalva, are rarer still. This wine has everything a great red tawny offers: harmony, complexity, and depth. But it has a lightness that is magical.
There are very few bottles left of 1963 Dalva white port. If you manage to find one, do not save it for a special occasion. Create instead a special occasion to enjoy it!
