Siete Misterios Mezcal - Siete Misterios produce a range of Mezcales, each one distilled from a single variety of agave. The agave are harvested at between 7-9 years of age, the outer leaves removed, and the hearts (pinas) roasted in a pit over a wood fire. The pinas sit on river stones and then are topped with Maguey leaves and earth to seal everything in. After approximately 72hrs the pinas are removed and ground using a horse-drawn mill and a series of hammer-like contraptions. Fermentation takes place next in wooden vats for between 2-3 days before being distilled in copper and clay stills.
