Tawny Port is aged in casks rather than large tanks or bottles like their Ruby counterparts. This gives them a lighter (in both body and colour) and silkier style. There are two major types of Tawny: a blend of several recent vintages with no specific statement of age – known as basic Tawny Port – and older-aged Tawnies, marked as 10, 20, 30 or 40 years old. They can be served chilled and are of great complexity; spices and dried fruit flavours abound. Colheitas are tawnies from a single year and are worth seeking out.
