Zuazo Gastón are two surnames closely linked to the viticulture of Oyón, one of the key locations to understand the prestige enjoyed by the wines of Rioja Alavesa worldwide. Although their winemaking origins date back to 1850, it was not until the mid-20th century that Mariano Zuazo, together with Victoriano Gastón and several local winegrowers, founded a cooperative that would eventually become the seed for the creation of Bodegas y Viñedos Zuazo Gastón in 2001. Today, the winery has 52 hectares of its own vineyards (plus another 48 hectares leased), a production capacity of nearly one and a half million liters, and a barrel park with 2,000 units.
