For Gran Patron Piedra, it all starts with 100% Weber Blue agave grown in the Highlands of Jalisco, Mexico, of which only the best are selected for this, Gran Patron Platinum and Gran Patrón Burdeos. The agave is slowly steam-cooked before being crushed with a two-ton Tahona. The Tahona is a traditional method that utilizes a two-ton volcanic stone wheel to extract the sugary juice from the agave, which is then fermented, distilled, and aged in barrels. Piedra, which means “stone” in Spanish, is created entirely from the traditional Tahona process – a process that few tequilas are made with anymore.
