For port wines, the word "tawny" indicates that the wine has been aged in wood for several years. Simple tawny ports must spend an average of seven years in pipes (large wooden vessels). Other categories of tawny include 10-, 20-, and 30-year-old tawny port. An aside, tawny port is one of the best buys among all fortified wine styles. Tawny can also refers to a wine's tan-like color.
