We were so smitten with the initial batch aged in extra añejo tequila barrels that we brought in more barrels and brewed more beer specifically to fill them. The barrels smelled amazing, with aromas of vanilla crème brulée, dulce de leche and tequila. The result is both satisfyingly expected and surprising at the same time: Sweet caramel-like flavors, black pepper, vanilla and tequila notes meld seamlessly with the spice, roasted coffee and chocolate flavors of the base beer for a richly intense experience.
