Sherry is a fortified wine made from white grapes that are grown near the town of Jerez, Spain. In Spanish, it is called vino de Jerez.
The word "sherry" is an anglicization of Jerez. In earlier times, Sherry was known as sack (from the Spanish saca, meaning "a removal from the solera"). "Sherry" is a protected designation of origin; therefore, all wine labeled as "Sherry" must legally come from the Sherry Triangle.
After fermentation is complete, Sherry is fortified with brandy. Because the fortification takes place after fermentation, most sherries are initially dry, with any sweetness being added later. In contrast, port wine (for example) is fortified halfway through its fermentation, which stops the process so that not all of the sugar is turned into alcohol
