As Tawny ports age, they grow lighter in colour, as they throw their deposit in the cask rather than in the bottle. The process of racking contributes to the oxidation process whereby the wine's fruit qualities gradually diminish and its nutty characteristics are acquired.
Fonseca 20 Year Old Tawny is deep amber in color with russet highlights. Its superb bouquet is a complex marriage of ripe, plummy, mature fruit, warm spicy overtones of cinnamon and butterscotch and subtle oak nuances.
