González Byass is one of Spain's best known Sherry bodegas. It is most widely known for its flagship brand Tío Pepe, although it produces a full range of Fino, Manzanilla, Oloroso, Amontillado and Pedro Ximénez sherries.
The company is made up of several individual bodegas with various solera barrel systems, including La Concha (The Shell) with an unsupported circular roof engineered by the Eiffel studio (who designed the Eiffel Tower) in the 1860s. The Tío Pepe bodega was finished in 1963 and holds 28,000 sherry butts on three floors, while the huge Las Copas facility, built in 1972, holds 80,000 butts.
González Byass was founded in 1835 by Manuel María González Angel and Robert Blake Byass. The González family were responsible for installing Spain's first electricity and running water at the plant, and were involved in various other innovations in Spain. González Byass also owns the Viñas del Vero company which produces 40 percent of wine in the Somontano DO, Vilarnau Cava in Penedés, Bodegas Beronia in Rioja and Rueda, Finca Moncloa in Cadiz and Finca Constancia in Toledo.
González Byass was rated number six in the '100 Best Wineries of 2014' list compiled by the World Association of Wine Writers and Journalists.
