Mezcal Unión Uno uses farm-grown Espadin agave and wild Cirial agave. This agave is cut and roasted for four days. The families that produce Union have three generations experience as their main craft and it shows. This is a low-cost, high-value Mezcal. There are not many finer Mezcals (if any) at this price point. Earlier batches of Union Uno contained a third agave: Barril.
