“When you like what you do, and you're young, nothing is impossible,” says Doña Juanita Hernandez, one of a handful of female master distillers in Oaxaca, the heart of Mexico’s small-scale mezcal industry. She sits, tiny and relaxed on a wooden bench as we sip mezcal in her distillery, El Rey Zapoteco, in the Oaxacan town of Santiago Matatlan. Doña Juanita herself was just a young girl when she started filling and labeling the bottles at her uncle’s distillery. He was the first person to bottle in the town, which has a long-held tradition of mezcal production. “[His brand was] Mezcal Matatlan,” she remembers. “He bought a bottling machine – a tiny one for four bottles at a time, and he had me fill the bottles and put on the labels.”

Years ago, we were traveling with a friend through Belgium during a particularly cold spring when, after a long day, we decided to warm up at a local bar. We were happy – and a bit surprised – to find that they had a decent selection of Oaxacan mezcales. Filled with yearning for our warm homeland, we ordered two shots of mezcal made with tepextate, the agave with the longest lifespan among the 20 wild varieties used for making mezcal in Oaxaca. That first sip unleashed the mineral and herbal flavors of this lonesome agave plant – which can require up to two decades of maturation before it can be turned into mezcal – and took us to its terroir: a rocky Oaxacan landscape where the central valleys meet the mountains and the wind blows dry and gentle.
