Mezcal worm

A mezcal worm is an insect larva commonly found in certain varieties of mezcal produced in Oaxaca, Mexico. There are two main types of larvae typically associated with mezcal: the gusano rojo and the chinicuil, which is the caterpillar of the Comadia redtenbacheri moth. The gusano rojo, or red worm, is particularly favored for its distinctive flavor. It's important to note that while mezcal might contain a worm, authentic tequila never does.

The practice of adding larvae to mezcal is a relatively recent innovation, employed by some brands to enhance the drink's flavor profile. These larvae are usually preserved in pure alcohol before being added to the bottle. Brands such as Nacional Vinicola (NAVISA), known for producing Gusano Rojo and Dos Gusanos, were among the pioneers of this practice, and even well-known brands like Patrón have adopted it.

Another type of "worm" found in mezcal is the larva of the weevil known as picudo del agave. These weevils can infest agave plants, causing substantial damage and sometimes leading to the loss of up to 40% of maguey harvests. Efforts are underway to develop agave varieties that are resistant to these infestations. Interestingly, the picudo larvae are considered a seasonal delicacy in southeastern Mexico and can be roasted and consumed.
