Port wine
Properties
Port wine is typically richer, sweeter, heavier, and higher in alcohol content than unfortified wines. This is caused by the addition of distilled grape spirits that fortify the wine, but also halt fermentation before all the sugar is converted to alcohol, and results in a wine that is usually 19% to 20% alcohol.
Styles
Port from Portugal comes in several styles, which can be divided into two broad categories: wines matured in sealed glass bottles, and wines that have matured in wooden barrels.
Tawny
When a port is described as tawny, without an indication of age, it is a basic blend of wood-aged port that has spent time in wooden barrels, typically at least three years.
