González Byass is a family-owned company dedicated to the aging and ageing of sherry wines and brandies. Together with the famous Tío Pepe sherry, the company's flagship and world leader in sherry sales, the brandies Soberano, leader in Spain, and Lepanto complete the triumvirate of strategic brands of the group, both in the domestic market and in the 115 countries to which it exports. For more than 170 years, González Byass has been committed to research and high quality in its wide range of products. In the 1980s, González Byass undertook a commitment to the development of still wines, reflected in its physical presence in key appellations in Spain, such as Bodegas Beronia, Vilarnau, Finca Constancia and Finca Moncloa. It also acquired Chinchón anise, the only one that is 100% distilled.

In 2003, González Byass took another step forward in the world of beverage distribution with the creation of the company Summa. Following its policy of expansion in the wine sector, in 2008 González Byass acquired all the shares of the emblematic company Viñas del Vero, belonging to the Aragonese Designation of Origin. With this purchase, González Byass consolidated its position as one of the leading groups in the Spanish wine industry, with 1,844 hectares of its own vineyards and a total production of 49 million bottles, including wines and brandies.
