Don abrahams extra anejoThe Don Abrahams Extra Anejo is expertly crafted using traditional stone and brick ovens. The agave is 100% fermented in stainless steel tanks, before being carefully distilled twice in a stainless pot with a copper coil. After distillation, the tequila is aged in whisky and used barrels before being bottled at 40% ABV (80 proof). The entire process is organic, making it a truly high quality and authentic tequila.
