Raicilla is an agave distillate like mezcal - just made in a different state of Mexico (Jalisco, to be precise)
Bonete Raicilla Sierra is made with agave Maximiliana in a single distillation. The agaves are cooked above ground in an adobe oven with black oak firewood. They are then fermented with wild yeasts, and single distilled in a stainless steel alambic still.
