Before bottling, Siembra Azul's Reposado and Añejo rest in virgin American White Oak "medium toast" barrels from the Ozarks in Missouri. These barrels were selected bcause of the impact the virgin oak from this region has on the flavor profile of Siembra Azul. The Reposado is aged for 3 months and the Añejo rests in these barrels for 12-36 months. The Añejo is bottled when the Master Distiller feels it is at its prime.
