Barrels Used for Tequila Aging

This is an amazing aspect to the Tequila world because using barrels that impart familiar flavors from other expressions can provide a more approachable bridge to a new Tequila drinker. For example, a Jack Daniels fan might be intrigued to try a Tequila in the Partida line since they use only Jack Daniels barrels in their aging process. Or a red wine drinker might be drawn to a Compoveda Extra Añejo after discovering that this Tequila spends 5+ years resting in California red wine barrels. What is your favorite barrel aged beverage you’d love to see in the Tequila world?
