Picture of a field of espadin agave (Agave angustifolia) taken at the mezcal factory Tres Colibries (Three Hummingbirds) in Villa Sola de Vega, Oaxaca State, Mexico, on July 26, 2022. - Craft distillers fear mezcal will become victim of its own success. The fast-growing popularity of Tequila's lesser-known cousin is raising concerns about its sustainability as strong demand means that more land, water and firewood are needed to grow the agave plants and distill the smoky spirit. Faced with the boom, craft producers are committed to saving wild species by planting them and showcasing the artisanal process behind the liquor. (Photo by Pedro PARDO / AFP)
