The story
Welcome to the beating heart of Oaxaca City. As you walk down the cobblestones of Calle Porfirio Díaz, take a deep breath. You can smell it, can’t you?
That faint, sweet scent of woodsmoke and roasted agave drifting from the open doorways of the mezcalerías lining this street. You are standing in the world capital of mezcal, a place where history is bottled and served in small clay cups. But as you look into the windows of these shops, past the hand-painted signs and the glowing orange lights, you’ll notice something swimming at the bottom of many bottles.
A small, pale, segmented creature. The famous mezcal worm. For decades, travelers have told tall tales about this little larva.
Some say it’s a powerful aphrodisiac; others claim it holds hallucinogenic properties or that it’s an ancient Aztec tradition. But as we stroll past the historic stone walls of the nearby Templo de Santo Domingo, let me let you in on a little secret: the worm is perhaps the greatest marketing trick in Mexican history. Back in the 1940s, a man named Jacobo Lozano Páez was working at a distillery.
He discovered that a certain type of agave moth larva, known as the chinicuil, occasionally found its way into the roasting pits. He realized that the larva changed the flavor profile of the spirit, adding a distinct earthiness. But more importantly, he saw a branding opportunity.
In 1950, he began intentionally adding the worm to his bottles of Gusano Rojo, and the rest is history. It was a genius move to make his product stand out on dusty liquor shelves, transforming a common agricultural pest into a badge of authenticity and a dare for brave tourists. In reality, the finest mezcals you’ll find here on Porfirio Díaz rarely contain a worm.
If you step into a high-end tasting room like Mezcalería In Situ, you’ll find that the true masters focus on the agave’s terroir and the craft of the palenquero. However, the worm hasn't vanished. It has simply evolved.
Today, it’s most commonly enjoyed as sal de gusano—a savory, smoky salt made from toasted larvae, dried chiles, and sea salt, served alongside a slice of orange to open up your palate. So, as you continue your walk, look closely at the bottles in the window displays. Whether it’s a clever gimmick or a flavor enhancer, the worm helped put Oaxaca on the map.
Tonight, find a quiet stool in a candlelit corner, order a glass, and decide for yourself if the legend lives up to the liquid. Just remember: in Oaxaca, we don’t drink mezcal; we kiss it, one small sip at a time.
