Dr. Stoner’s Tequila Hierba Madura is made by maturing their Tequila Hierba Loca in freshly dumped Virginia bourbon barrels for one year or more. 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 accent followed by the familiar agave finish, fruity, floral and slightly smoky. At 84 proof, this uniquely made 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.
