Tío means uncle in Spanish, with the brand being named after the beloved uncle Pepe of founder Manuel María González Ángel. Manuel was only 23 years old when he began his business in 1835, in Jerez, Spain. Today, Tío Pepe is a globally recognised Sherry brand and is still produced by the fifth-generation descendants of Manuel. The Byass, in the company name González Byass, is the result of the partnership with their English sales agent and wine merchant Robert Blake Byass which began in 1844.
