Porto DOC (Douro Valley)
The world’s reference fortified-wine region (Port). Terraced schist slopes of the Douro valley produce Vintage Port that ages 30-50+ years.
About Porto
The Douro Valley is one of the world’s oldest formally demarcated wine regions — the boundaries were set in 1756 under the Marquês de Pombal, predating most European appellation systems by 100+ years. The region produces both unfortified Douro DOC wine (covered separately as a category) and fortified Port wine. Port is fortified with neutral grape spirit during fermentation, which kills the yeast and leaves residual sugar — producing the sweet, high-alcohol (typically 19-22% ABV) wine the region is famous for. The Port style hierarchy includes Vintage Port (declared only in exceptional years, bottled young, aged in bottle 20-40+ years before reaching peak), Late Bottled Vintage (LBV, ready-to-drink), Ruby Reserve, Tawny (cask-aged, with 10/20/30/40-year age statements), Colheita (single-vintage Tawny), and Vintage Character. The terraced schist slopes — some constructed by Roman labor — are now a UNESCO World Heritage site. The five major Port houses (Taylor Fladgate, Graham’s, Croft, Warre’s, Dow’s) control most of the prestige Vintage Port category.

Editorial notes
Vintage Port requires 20-30+ years cellaring from declared vintages. Tawny Port doesn’t require further bottle aging — it’s drink-now style. The 1945, 1955, 1963, 1977, 1985, 1992, 1994, 2000, 2007, 2011, 2016, 2017 vintages are landmark.
