Sherry is a fortified wine made from white grapes that are grown near the town of Jerez (Jerez de la Frontera), 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"). In Europe, "Sherry" is a protected designation of origin; in Spanish law, all wine labeled as "sherry" must legally^[1] come from the Sherry Triangle, which is an area in the province of Cádiz between Jerez de la Frontera, Sanlúcar de Barrameda, and El Puerto de Santa María. In 1933 the Jerez Denominación de Origen was the first Spanish denominación to be officially recognized in this way, officially named D.O. Jerez-Xeres-Sherry and sharing the same governing council as D.O. Manzanilla Sanlúcar de Barrameda.
