Jose Cuervo Black Medallion Oak Barrel Signature Blend Añejo Tequila The agave foundation is buried under aromas of oak extract, vanilla and dark caramel. The palate entry is concentrated and sweet, with no natural agave herbaceousness; the midpalate mirrors the manufactured sweetness of the entry. Finishes warm, woody and smoky-sweet. A very dark anejo from Cuervo, referred to in the bumf as their Signature Blend. Innovative serving suggestions included were on the rocks and with cola.
