Many Worms Mescal uses this time honored principle to completely rid our Mescal of all toxins and impurities by first filling the bottle with worms before filling it with mescal. Nestled among the interstices of the worms, this mescal is purified to a high drinkability. The opaque cloudiness is a natural result of this process. BUNGCO scientists have determined that the addition of a variety of worms improves the beverage even more, and so (depending on availability) you may find up to 80 different worm, grub and caterpillar species in your bottle. Collect all 80!
