Monte Alban is one of the most widespread Mezcals in the U.S. It is carried by many distributors and liquor stores, and (for better or worse) it is what many people associate with the word “Mezcal.” Monte Alban has been making Mezcal and selling it in the U.S. for a long time. They are well established in the market, and many have had the experience of “tasting the Mezcal worm” with their signature Reposado.
