Not many people realize that tequila can only be made from one specific species of agave… The Blue Weber. In accordance with the “Declaración de Denominación de Origen Tequila” or "Appellation of Origin Declaration," which specifies the region and methods for tequila production, Tequila makers are required by law too use Blue Weber only in tequila production. A fully mature Blue Weber plant can take anywhere from 5 to 9 years to grow with plant sizes reaching 5 to 8 feet tall and leaves extending 4 feet wide. The state of Jalisco where Blue Weber is grown is one of the most important cultural landscapes in Mexico and it is where your favorite Una Vida tequila is made.
