From estate grown agave at 7,000 feet above sea level. Slow roasted in brick ovens for 72 hours, the Avión agave is distilled and filtered through Avión’s proprietary ultra-slow filtration method, where it is then aged for 43 months in oak barrels to create a smooth and balanced finish. The final step for Avión Reserva 44 is aging the liquid for an additional month in specially selected petite barrels, which are rotated daily. It is during this intensive process, the brand says, that Reserva 44 takes on its rich, complex character. The liquid is then hand-filled into a fire polished crystal bottle, hand numbered and individually signed by Founder, Ken Austin. Only 744 cases produced.
