SilverCoin, Santa Fe Tequila Company’s Incredibly Smooth, Silver Tequila. SilverCoin is 100% Blue Weber Agave and, unlike all other tequilas on the market, it is distilled to proof. SilverCoin stops the distillation at 80 proof, leaving more Pure Agave Sugar in the final product. This, combined with twenty-eight days of aging in oak barrels, gives SilverCoin a smooth richness while still allowing the Bright True Agave flavors of a Classic Silver Tequila to shine through.
