Union is one of the most commonly found mezcals. They are at the forefront of sustainable agave farming, which is a growing concern for the industry. They also put a heavy emphasis on paying their mezcaleros and others who work on their production very well. Their story says that when starting the company, an old man told them that the future of mezcal would be based on a UNIÃ“N. That's how they named the company, and that's how they decided to make a mezcal that featured different producer families. Though Pedro Hernandez is their master mezcalero, each bottle is produced by a union of Oaxacan families. There may be slight variations of flavor from batch to batch. In February of 2017, Mezcal Union signed a distribution agreement with Diageo. The agreement keeps the ownership of Union in the hands of its founders, while opening the doors to a wider distribution network.
