The History and Origins of Mezcal

Mezcal's story stretches back centuries before the spirit had a name, rooted in the intersection of indigenous agricultural knowledge, volcanic landscape, and a plant that takes decades to mature. This page traces that history from pre-Columbian fermentation practices through the colonial-era invention of distillation, the regulatory formalization of the 20th century, and the denomination framework that governs production today. Understanding where mezcal came from clarifies why it looks, tastes, and behaves the way it does — and why debates over its future remain so charged.

Definition and Scope

Mezcal is a distilled spirit produced from the cooked hearts — the piñas — of agave plants, and its legal definition is anchored to a specific geographic Denomination of Origin covering 9 Mexican states as of the 2016 expansion of the official mezcal territory (Consejo Regulador del Mezcal). The word itself is derived from the Nahuatl mexcalli, meaning cooked agave — a fact that quietly confirms the deep pre-distillation history of the ingredient, since indigenous communities were cooking and consuming agave long before anyone thought to run it through a still.

The scope of mezcal history is genuinely vast. It involves at least 3 distinct eras: a pre-Columbian period characterized by fermented agave beverages; a colonial period in which Spanish distillation technology fused with indigenous ingredient knowledge; and a modern regulatory period beginning formally with Mexico's first mezcal standard, NOM-070, published in 1994. Each era left structural marks on what mezcal is today — which is a more complicated origin story than the spirit's artisan reputation sometimes implies.

Core Mechanics or Structure

The foundational act in mezcal's history is the roasting of agave hearts in earthen pits, a technique that hydrolizes the plant's starches into fermentable sugars and simultaneously imparts the characteristic smokiness that distinguishes mezcal from tequila at a sensory level. This method almost certainly predates distillation by at least 2,000 years, based on archaeological evidence of roasting pits and agave fiber remnants found at sites in Oaxaca and Puebla.

The Zapotec and Mixtec peoples of what is now Oaxaca consumed pulque — a fermented agave sap beverage — and also roasted agave piñas as food. The leap from roasted-agave food to fermented-agave drink to distilled spirit required the introduction of copper or clay pot stills, which arrived with Spanish colonizers in the 16th century. Some researchers, including those cited in work published by the Universidad Nacional Autónoma de México (UNAM), argue that Filipino distillation techniques introduced via the Manila Galleon trade routes in the late 1500s also contributed to early mezcal production methods, particularly the clay pot still design still used in certain ancestral productions today.

The result of that convergence: a distilled spirit that carries the genetic memory of an ancient agricultural relationship with agave, expressed through a production process that has changed remarkably little in some communities over 400 years. The mezcal production process is still largely manual, pit-fired, and fermented in open-air wooden or stone vessels in artisanal contexts.

Causal Relationships or Drivers

Three factors drove mezcal's historical development in ways that continue to shape the industry.

Agave biology. Agave plants require between 7 and 35 years to mature depending on species and altitude, which meant mezcal production was never suited to rapid industrialization. Communities that grew agave were necessarily tied to long-term land relationships — a structural feature that preserved regional variety. The documented use of over 30 agave species in mezcal production (agave varieties used in mezcal) is a direct consequence of this regional, unhurried agriculture.

Colonial taxation and prohibition. The Spanish Crown periodically banned or taxed mezcal production in the 17th and 18th centuries to protect the market for Spanish wines and brandy. These restrictions pushed production into remote villages in Oaxaca, Guerrero, and Durango — which paradoxically preserved traditional methods by keeping production small, hidden, and community-controlled.

Oaxacan geography. Oaxaca's mountainous terrain and relative political isolation meant that even after independence in 1821, industrial-scale production never took root there the way it did in Jalisco, where the blue agave monoculture supporting tequila production became the commercial norm. The mezcal-producing regions of Mexico reflect exactly this dispersed, terrain-driven geography.

Classification Boundaries

Mezcal became a legally defined category in Mexico through NOM-070-SCFI-1994, the Norma Oficial Mexicana that established the first formal production standards. This was a significant institutional moment: tequila had already received regulatory protection in 1974 under its own Denomination of Origin, and mezcal's later formalization partially reflected the need to distinguish the broader category from its more commercially prominent cousin.

The Consejo Regulador del Mezcal (CRM) was established in 1997 as the certifying body. By 2016, the official Denomination of Origin for mezcal had expanded to include 9 states: Oaxaca, Guerrero, Durango, San Luis Potosí, Zacatecas, Tamaulipas, Guanajuato, Michoacán, and Puebla. Importantly, this boundary is regulatory, not ecological — agave grows and has been distilled well beyond those borders, but only production within designated territories using certified methods qualifies as mezcal under Mexican law.

The mezcal categories and classifications framework introduced the three-tier production hierarchy — Ancestral, Artisanal, and Industrial — reflecting a deliberate attempt to encode historical production methods into commercial labeling.

Tradeoffs and Tensions

The regulatory formalization of mezcal has generated a persistent tension between protection and commercialization. The same certification infrastructure that guards against fraudulent labeling also imposes costs that small, indigenous producers often cannot absorb. A Oaxacan family operating a traditional palenque — the term for a mezcal distillery — may produce spirit in exactly the way their community has for generations while technically operating outside CRM certification, which requires fees, paperwork, and ongoing compliance.

There is also the ecological dimension. The rise of mezcal in the United States — US mezcal imports grew from roughly 150,000 liters in 2005 to over 6 million liters by 2019 (Consejo Regulador del Mezcal annual data) — generated demand pressure that accelerated wild agave harvesting in ways that threaten long-term population viability. The wild vs. cultivated agave debate is not academic; it is a direct consequence of commercial growth colliding with a plant that cannot be speed-farmed.

The mezcal maestro palenquero tradition — the deep craft knowledge embedded in individual producers — also faces transmission risk as commercial incentives pull younger generations toward brand employment rather than independent production.

Common Misconceptions

Mezcal is just smoky tequila. This conflates two distinct denominaciones de origen. Tequila is produced exclusively from blue agave (Agave tequilana Weber) in a defined region of Jalisco and 4 other states. Mezcal can be produced from over 30 species, in 9 states, using a range of production methods. Smoke is one possible characteristic — not a defining requirement, and not present in all mezcals.

All mezcal is ancient and artisanal. The three-tier classification exists precisely because industrial mezcal production is real and legal. Diffuser-extracted, column-distilled mezcal exists within the denomination, though it must be labeled accordingly.

Mezcal always has a worm. The worm — technically a larva from the Hipopta agavis moth — is a marketing invention that became associated with certain mezcal brands beginning in the 1940s and 1950s. It has no traditional or indigenous basis in mezcal production. The mezcal and sal de gusano tradition involves the larva in condiment form, which is a legitimate regional practice, but is distinct from bottle-worm marketing.

Mezcal is a new category. The spirit has been produced continuously in Oaxaca since at least the 16th century. What is new is the international market for it — a distinction worth holding onto when evaluating claims about authenticity.
