The vast majority of Mexico's 500,000 coffee producers are smallholder farmers and have one hectare or less of land under coffee. Union San Pedro represents around 180 coffee producing families.

This coffee is a mix of two varieties that are typical to the Sierra Sur: Mundo Novo and Pluma Hidalgo. Pluma Hidalgo is a variant of the Typica variety and was developed in the Sierra Sur, in the town of Pluma Hidalgo just a few miles from San Pedro.
