The agave for Don Julio’s Tequila is grown in the highland area of Atotonilco on the family estate. Tequila’s major aging process over time takes place in conjunction with the development of agave plants, given that they take seven years to reach maturity. Every agave plant is harvested by hand. The agave plant is cut from its roots and then the spearlike leaves are sheered off. The core that is left is called a piña, which is the raw material used for the making of tequila. The piñas are transported on a truck to Don Julio’s Distillery where they are cut into equal sized pieces so that they bake evenly. The piñas are loaded into brick ovens where they are slowly baked over the course of several days. Then the baked piñas are crushed and doused with water, which releases the sweet agave syrup called agave juice. Then yeast is added to the agave water and is left to ferment. After the fermentation process is complete it results in a sweet, slight alcoholic agave beer which is then put into stills where it is distilled to become tequila. At last it is put into stainless steel tanks before bottling, or ex-bourbon casks for aging.
