As it matures in cask, Tawny Port gradually loses the deep red \'ruby\' colour of youth and takes on the seductive amber hue known as \'tawny\'. At the same time the wine becomes progressively smoother and mellower, its aromas gaining in richness and complexity.The fruit has mellowed further in the 20 Year Old. Tasting NotesFonseca 20 Year Old Tawny is deep amber in colour 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.
