Sombra Mezcal – Fire, Rock and Earth – That\’s all it takes. Espadin Agave are hand harvested on the steep slopes of the Oaxacan Sierra. The hearts are slowly roasted in a rock pit over a mesquite fire and then ground, brewed, and expertly distilled. The result, Sombra, is one of the most tasteful and finest spirits produced on and of our earth.
