Jerez de la Frontera is part of the famed Sherry Triangle in southern Spain. This region, along with Sanlúcar de Barrameda and El Puerto de Santa María, forms the heart of an area where wine have been cultivated for ages, producing some of the world's most known wines.
The Moors introduced distillation in the south of Spain, leading to the development of brandy and fortified wine. It was in a town known as Sherish, that became the origin of both the term "sherry" and the city's name, Jerez. Jerez became popular with wine merchants from across Europe because of the rising demands for sherry, especially from Britain. It lead to a movement of merchants like Domecq, Osborne, Gordon, and Terry to Jerez. These merchants not only traded but also cultivated wines. Some of these names are in the 20th century know well known wine brands.
Sherry is considered a fortified wine due to the addition of distilled alcohol during the winemaking process, resulting in an alcohol by volume (ABV) range of 15%-22%. Jerez is the largest city in the province of Cádiz.
