Roca Patrón Silver is handcrafted from the finest 100% Weber Blue Agave at Hacienda Patrón distillery. After baking for 79 hours in small brick ovens, the agave is pressed by a two-ton volcanic stone tahona wheel, then fermented and distilled on its own fibers. Roca Patrón Silver is specifically finished at 90 proof to create a crisp, robust tequila with notes of sweet agave. Patrón Tequila has always been Additive-Free because of our unwavering commitment to craft, authenticity, and integrity.
