Crisp, clean, and versatile, Xoma is neither a mezcal nor a tequila but their tastier, older cousin, a pulcatta. Xoma is hand-crafted and sustainably produced, with each bottle purchased providing a reliable income to over 200 farmers, helping maintain their 2,000 year old heritage of pulque production. Xoma is a new, sustainable agave spirit with a 3P mission. ... A superior tasting smooth agave spirit. Neither mezcal nor tequila, Xoma is made from 100% pure agave aguamiel that naturally ferments to become pulque – a probiotic drink – before distillation. No cooking, smoking, or smashing involved.
