Mezcal Day 2025: Tradition, Diversity, and Environmental Consciousness

LEE LA NOTA EN ESPAÑOL

To talk about mezcal is to talk about Mexico itself. It’s not a trend or something new—it’s knowledge that’s been passed down through generations, still alive and evolving. In every bottle lives the land, the history, and the people who made it. A spirit born from a system that learned to work with nature, not against it.

Mezcal is going through one of the most important moments in its history. This is pushing us to reconsider what we really mean by origin, why artisanal craftsmanship matters, and how deeply culture and sustainability are intertwined.

The Beginning

Long before the Spanish came, agave was part of everyday life. The Zapotec and Mixtec people roasted it in cone-shaped earthen ovens to get the juice for fermented drinks. These drinks were part of regular meals and also important ceremonies.

Then the Spanish arrived and brought distillation with them. Local workers adapted the stills using what they had available, and that’s how mezcal started. Over time, it spread across different regions of Mexico, with each community developing its own approach.

Designations of Origin

In 1994, Mexico created the Mezcal Designation of Origin to protect where mezcal can legally be made.

Oaxaca accounts for roughly 90% of all certified mezcal, though it’s also made in Guerrero, Durango, Zacatecas, and San Luis Potosí. Several municipalities in Michoacán, Puebla, Guanajuato, Tamaulipas, Morelos, Aguascalientes, and Estado de México are also authorized producers.

The soil, the climate, and the type of agave growing there all shape what makes one mezcal distinct from another. Each region brings its own character.

How It’s Made

The process brings together traditional technique and the natural environment.

Agave hearts are slow-roasted in conical earthen ovens layered with volcanic stones and wood for several days. They’re then crushed using wooden mallets or a tahona—a large stone wheel traditionally pulled by animals.

The juice and pulp ferment in wooden or stone vessels using natural yeasts. After fermentation, the liquid is distilled twice, either in clay pots or copper stills, depending on the production style.

Mexico’s Official Standard NOM-070 governs these processes and classifies mezcal based on production method and how long it ages before bottling.

By Production Method

This reflects how much handwork versus machinery is involved.

Ancestral Mezcal Pure hand labor, no modern equipment.

• Roasting: Conical earthen oven
• Crushing: Wooden mallets or animal-drawn tahona
• Fermentation: Wooden, stone, or leather vessels, including agave fibers
• Distillation: Clay pots over open flame

Artisanal Mezcal What most producers make today.

• Roasting: Earthen or brick oven
• Crushing: Tahona, mallets, or mechanical grinder
• Fermentation: Wood, stone, clay, or stainless steel
• Distillation: Copper stills over direct heat

Mezcal (Standard Category) Allows larger industrial-scale production with mechanical roasting, grinding, and fermentation in steel tanks. Generally produced in higher volumes with a focus on consistency.

By Aging

How long the mezcal rests after distillation determines its character.

Joven (Blanco) Bottled fresh or after brief resting in steel or glass. This is where you taste the agave and smoke most clearly.

Reposado Aged in wooden barrels for 2 to 12 months. It softens, developing subtle wood-influenced flavors.

Añejo Aged in barrels for over 12 months, gaining complexity and a distinctive golden hue.

Glass-Aged Rested in glass for at least a year, usually buried underground. Produces a rounder, smoother profile without wooden influences.

Special Categories

Abocado con… (Infused with…) Finished young mezcal has ingredients added and left to macerate before bottling.

• Process: Post-distillation infusion
• Timing: After final distillation
• Result: The ingredient infuses its flavor, aroma, and often color directly into the spirit
• Classic example: “Mezcal con Gusano”—the maguey worm added to the finished bottle. You’ll also find versions infused with damiana, tropical fruits, honey, or regional herbs.

Destilado con… (Distilled with…) A more complex, traditional method often reserved for special releases or ceremonial batches.

• Process: An additional distillation, typically the third
• Timing: Already-distilled mezcal returns to the still with ingredients inside
• Result: Alcohol vapors pass through the ingredients, capturing their subtle, volatile essences. The final spirit remains crystal clear but carries fully integrated, layered flavors.
• Classic example: “Mezcal de Pechuga”—seasonal fruits, spices, and almonds placed in the still with a raw chicken or turkey breast suspended above the liquid. The rising vapors gently cook the meat and infuse its essence, adding a distinctive savory note that balances the fruit.

Environmental Pressures

Deforestation and Fuel Consumption

The growth of mezcal production has created real environmental challenges. The characteristic smoky flavor comes from roasting agave in wood-fired earthen ovens.

Producing a single liter requires roughly 7 to 10 kilos of wood—typically oak, pine, or mesquite.

Rising demand has driven illegal logging and significant forest loss, particularly in Oaxaca. Forest depletion reduces water retention, causes soil erosion, and disrupts local ecosystems.

The Vinaza Crisis

Every liter of mezcal generates 10 to 12 liters of vinaza, the acidic liquid residue from distillation. When released untreated into rivers and soil, it contaminates water, suffocates aquatic life, and renders land infertile. While some distilleries have started implementing treatment and composting systems, there’s still no widespread regulatory framework.

Overexploitation of Wild Agaves

Demand for wild agaves has increased because of their complex flavor profiles, but supply can’t keep up. Standard Espadín takes 6 to 8 years to mature; Tepeztate can take up to 35 years. Uncontrolled harvesting prevents regeneration and threatens species like Tobalá and Cuishe. Additionally, cutting agaves before they flower harms their natural pollinators—particularly bats, which are vital to ecosystem health.

Women Reshaping the Industry

For generations, women performed essential work in mezcal production—managing distilleries, overseeing fermentation, maintaining sales networks—yet remained unrecognized as master mezcaleros. That’s changing.

A new generation is stepping into leadership roles, building their own brands and setting industry standards. Graciela Ángeles Carreño of Real Minero leads the way in preserving ancestral methods and sustainable agave practices. Berta Vásquez of Mezcal Vago is renowned for her mastery of clay pot distillation. Sosima Olivera of Mezcal Sola organizes producer collectives throughout Oaxaca.

Structural barriers remain—access to land, financing, market entry—but these women’s voices now shape how mezcal is made and preserved.

Present & Future

Mezcal has expanded from local production to international markets while retaining much of its artisanal soul. The challenge ahead is maintaining quality and tradition without compromising environmental health or fairness throughout the value chain. This expansion offers a real opportunity to strengthen producing communities and protect the natural resources that make mezcal possible.

Celebrating Mezcal Day isn’t just about raising a glass. It’s about honoring everything that goes into it.
