Patron kicked off the premium tequila movement, so it’s no surprise that the brand is now offering one of the most expensive and aged extra añejos on the market. Unlike most tequilas, Gran Patron Piedra (“piedra” is Spanish for “stone”) is produced using a very traditional process of using a stone wheel (called a “tahona”) to slowly crush the agave. The resulting juice is then fermented and distilled along with crushed agave fiber. It’s then aged for a minimum of three years in new American and French oak barrels.
