What mezcal is
Mezcal is a spirit distilled from cooked, fermented agave. The word is also used more broadly for the family of agave spirits, of which tequila is a specific, separately regulated member. The two are related but not identical, and their production, legal framework and character differ. Mezcal is protected by a denomination of origin that covers Oaxaca, where most production happens, and a number of other states, with a list that has been revised over time. Anyone seeking precise details should check the current official rules.
Mezcal is a cultural subject as much as a drink. It is closely tied to rural communities, regional identity and ceremony. This article is an explanation of the craft, not encouragement to drink, and alcohol is for adults.
Many agaves, not one
Where tequila is limited to one species, mezcal can be made from a wide range of agave species. One cultivated variety, often called espadin, is the most widely used, but producers also work with wild and semi-wild agaves, some of which take many years to mature, sometimes well over a decade. Different species produce different flavors, in the same way that grape varieties do. Because mature agaves are harvested once and the plant dies, sustainability and replanting are real concerns in the discussion around mezcal.
Step by step
Harvesting
The agave plant stores sugar in its heart, called the pina because it looks like a large pineapple. Workers called jimadores cut away the long leaves to extract it.
Roasting
Traditionally the hearts are cooked in an earthen pit. A fire of wood or charcoal heats stones lined at the bottom of the pit. The hearts are layered over the stones, covered with fiber mats or leaves and then earth, and left to cook for days. This slow roasting converts the plant’s complex starches into fermentable sugars and gives mezcal much of its smoky character. The technique has similarities with pit barbacoa, though it is applied to a plant rather than meat.
Milling
The roasted agave is soft, fibrous and sweet. It is crushed to release the juices. Traditional methods include a large stone wheel, called a tahona, turned by an animal or motor, or hand-mashing with mallets. Larger operations may use mechanical shredders.
Fermentation
The crushed agave, usually with its fibers, is placed in vats along with water and left to ferment. Vats may be wood, stone, clay, or in some cases animal hide or stainless steel. Many producers rely on wild yeasts and bacteria in the air and on the plant, so the process depends on weather and temperature, and takes anywhere from a few days to a couple of weeks.
Distillation
The fermented liquid is distilled, typically twice, in stills made of copper or clay. Traditional methods use small batches. The first distillation produces a low-alcohol liquid, and the second raises the alcohol level and refines the flavor. Skilled distillers separate the heads and tails of each run, keeping the middle “heart” for the final product. Some producers add ingredients such as meat or fruit to the second distillation, which is the origin of certain “pechuga” styles.
Categories and labels
Official categories reflect production methods. In general terms:
- Mezcal is the broadest category and can include more industrial methods.
- Artisanal mezcal (artesanal) uses traditional techniques such as pit roasting and fermentation in open vats.
- Ancestral mezcal uses the most traditional methods, with clay pot distillation, among other criteria.
Age statements such as joven (young), reposado and anejo resemble tequila terms and refer to time in wood. Many mezcals are bottled unaged. Check the label for the agave species, producer, region and batch, which can tell you more than the category does.
How it is traditionally served
Mezcal is usually sipped slowly, often from small cups of clay or glass, with slices of orange and a salt mixed with ground dried larvae and chile known as sal de gusano. These accompaniments vary, and some people prefer to drink it plain. It is also used in cocktails, though tradition emphasizes sipping. Alcohol should be treated with respect: drink in moderation if you drink at all, never before driving, and not at all if you are underage, pregnant or unwell.
Culture and place
Mezcal is a part of daily and festive life in many Oaxacan towns, where family workshops pass down knowledge across generations. It features in wedding celebrations, community festivals and gift-giving. Visitors to markets and producing regions often encounter it alongside the foods of Oaxacan cuisine, and it comes up wherever people discuss the Oaxacan moles and the wider regional table.
Reading a bottle
- Look for the producer and region, not only brand names.
- Check the agave species and the process notes if provided.
- Remember that “artisanal” is a regulated term, but marketing language beyond that is not always precise.
- Prices and quality vary widely, and a wild, slow-growing agave takes years to mature.
Mezcal differs from one village and one batch to the next. That diversity is the point, and learning to appreciate it takes time.
