Siete Misterios Espadin was the first mezcal expression that Siete Misterios released. While on a trip into the Sierra, they visited the small community of Sola de Vega. The mezcal they tasted there was all hand milled and clay pot distilled, which they noted as giving the mezcal sweeter and spicier features compared to mezcal made in other regions. After tasting this mezcal, they knew that it was the one they needed to release. At about 50% ABV, this mezcal is smooth, and it is always distilled to proof.
