Dr. Stoner’s Tequila Hierba Madura is made by maturing our Tequila Hierba Loca in freshly dumped Virginia bourbon barrels. The agave is caramelized in a stone oven, then infused with Dr. Stoner’s special stash of herbs. The initial taste and aroma is a silky smooth bourbon flavor. This is followed by the familiar agave flavor, fruity, floral and slightly smoky. At 84 proof, this one of a kind premium tequila is perfect for sipping poured neat, chilled, or served straight up. It’s remarkably smooth and unique from any other barrel aged tequila.
