Tequila must be commercialized with an alcohol content of between 35 and 55% ABV, with 38 and 40 being the most common values. Its designation of origin, established in 1974, legally protects the name "Tequila" and restricts it to beverages produced from Tequilana Weber Agave, Blue Variety, within a specific geographic area of Mexico. At Casa Sauza, we have been producing tequila since 1873 in Tequila, Jalisco — the heart of that protected zone.
