Knowra Port wine Port wine Port wine is a sweet fortified wine made in Portugal’s Douro Valley. Grape spirit is traditionally added during fermentation, stopping it early and preserving natural grape sugars.
Fortification (wine) : The addition of distilled spirit to wine, raising its alcohol content and often changing its sweetness. Adding grape spirit during fermentation is what leaves port naturally sweet and stronger than ordinary wine.
Douro Valley : A wine-producing region in northern Portugal, centered on the Douro River and its tributaries. Port’s defined production region follows the steep vineyards of this valley.
Ruby port : A youthful, fruit-forward style of port aged to preserve its deep color and fresh character. It represents port’s less oxidative, fruit-led style.
Treaty of Methuen : A 1703 agreement between England and Portugal that lowered tariffs on Portuguese wines in England. The treaty strengthened the English market that helped port become an international trade wine.
Sherry : A fortified wine from Spain’s Jerez region, matured using distinctive aging systems and styles. Unlike port, sherry is usually fortified after fermentation and includes dry styles.
Aguardente : A Portuguese distilled spirit, commonly made from wine, used in traditional port production. This grape spirit stops fermentation while port still contains residual sugar.
Douro wine region : A Portuguese wine region whose wines include Port and unfortified Douro wines. The wider region provides port’s regulated geographic identity and production setting.
Tawny port : A style of port matured in wood until it develops a lighter color and oxidative, nutty flavors. Longer cask aging produces a contrasting, oxidative expression of port.
British wine trade : The historical commerce in wine between Britain and other regions, including Portugal. British merchants and consumers shaped port’s export history and commercial development.
Madeira wine : A fortified wine from the Portuguese island of Madeira, known for heat-influenced aging and high stability. Madeira’s characteristic heating and oxidation differ from port’s fermentation fortification and Douro aging.
