Brandy

Brandy, simply put, is a distilled wine. It is categorised under Distilled Alcoholic Beverages along with Whiskey, Rum, Gin, Vodka and Tequila, but it's in a way a cross connection between Fermented liquor and distilled liquor. A Brandy typically containts 35% to 60% Alcohol by Volume ( 70-120 US proof ) and is usually consumed as an after dinner digestif.

Although Brandy is generally classified as a liquor produced by distilling wine, in a broader sense, this encompasses liquors obtained from the distillation of either pomace ( the soild remains of grapes after mashing and extraction of juice for wine making ) or fruit mash or wine.

It may be noted that Brandy like Gin is also one of the original Water of Life or eau de vie, carried over from the medieval tradition of an aquaous solution of ethanol used as a medicine.

The history of Brandy is closely tied to the development of commercial distillation in and around the 15th Century. In early 15th Century French Brandy made way for a new cross-Atlantic trade or Triangle Trade and replaced Portuguese Fortified Wine or Port from the central role it played in trade, mostly due to the higher alcohol content of the Brandy and ease of transport. However by the late 17th Century, Rum replaced Brandy as the exchange alcohol of choice in the Triangle Trade. More info on Wikipedia for the interested Brandy aficionados. Note that an Apricot Brandy can refer to the liquor (or Eau de Vie, Water of Life) distilled from fermented apricot juice or a liqueur made from apricot flesh and kernels.
