"Parejo is the term used by a vinatero to describe when a sotol is perfect. They read the ABV of the spirit by passing it from one cuerno to another. They adjust by adding spring water until the perlas form from the center.

Sotol Parejo was founded by Jorge Caldera, who has devoted 13+ years to studying the native spirits of Chihuahua. Throughout that time, he met producers and built friendships. For many years, viñatas were considered illegal by the government. Because of this, Jorge found that a shared struggle existed among the maestros. Unfortunately, their craft was considered taboo.

The goal of Parejo Sotol from the outset was to recapture the historical taste of sotol."
