Mezcal is produced across at least ten Mexican states, though one dominates: Oaxaca accounts for roughly 85.5% of all mezcal made in the country. The remaining production spreads across Guerrero, San Luis Potosí, Durango, Puebla, Michoacán, and several other states that hold legal authorization to use the name “mezcal” on their labels.
The Denomination of Origin
Mexico protects mezcal with a Denomination of Origin, similar to how France protects Champagne. Only spirits produced in officially authorized regions can legally be called mezcal. As of 2025, ten states hold this designation: Oaxaca, Guerrero, Durango, San Luis Potosí, Zacatecas, Michoacán, Puebla, Tamaulipas, Guanajuato, and the State of Mexico (the most recent addition). Within several of these states, only specific municipalities qualify rather than the entire territory. For Oaxaca, Zacatecas, Durango, Guerrero, and San Luis Potosí, the entire state is authorized. Sinaloa, Aguascalientes, and Morelos also have some municipalities included in the designation.
This ongoing expansion has generated controversy. Producers in the original heartland states worry that broadening the geographic boundaries dilutes the spirit’s identity and quality standards. Some traditional distillers in states without authorization, or those who reject the certification process, sell their products as “destilados de agave” (agave distillates) instead. These uncertified spirits from places like Jalisco and remote mountain communities in Oaxaca are gaining a following among enthusiasts who value tradition over bureaucratic labels.
Oaxaca: The Heart of Mezcal
Oaxaca isn’t just the biggest producer by volume. It’s the cultural epicenter of mezcal, with production traditions stretching back centuries. The state’s production clusters in several distinct zones, each with its own character. The Valles Centrales region, including Santiago Matatlán (often called the “world capital of mezcal”), Tlacolula, Ocotlán, Ejutla, and Zimatlán, forms the most concentrated production corridor. The Sierra Sur, encompassing Solá de Vega, Miahuatlán, and Yautepec, is another major zone where many small family operations work with wild agave varieties in rugged mountain terrain.
What makes Oaxaca so productive is a combination of biodiversity and geography. The state is home to more agave species than almost anywhere else in Mexico, including the widely cultivated Espadín (Agave angustifolia) and prized wild varieties. The terrain shifts dramatically across short distances. Walk through Oaxaca’s agave fields and the soil changes color from rust-red to ashy gray, each type leaving a distinct mark on the spirit. Potassium-rich soils enhance caramelization during roasting, while calcium-heavy earth amplifies floral aromas during fermentation. Even the pH of the ground can push a mezcal toward bright citrus or deep, savory flavors.
Guerrero and Its Wild Agave
Guerrero contributes about 2.1% of national mezcal production, a small share that belies its outsized reputation for quality. The state’s signature is Agave cupreata, a wild plant known locally as “papalote” or “ancho” that grows beneath deciduous forests and oak trees in the Sierra Madre. This agave takes 7 to 10 years to reach maturity, and it requires roughly 14 to 17 kilograms of roasted plant to yield a single liter of mezcal.
The resulting spirit is distinctive. Guerrero mezcals made from cupreata tend toward tropical fruit aromas, sweet cooked agave, papaya, and a gentler smokiness than many Oaxacan expressions. The soft, rain-fed water of Guerrero’s tropical valleys contributes to rounder, fruit-forward profiles. Production in towns like Mazatlán, Guerrero typically follows traditional methods: agave hearts roasted in underground pits lined with lava rock for four days, crushed by mechanical mill, fermented with wild yeasts in open-air wooden vats, then slowly double-distilled in copper pots.
San Luis Potosí, Durango, and the North
San Luis Potosí produces about 2.5% of Mexico’s mezcal and occupies a completely different landscape from the southern states. Here, natural springs filter through limestone bedrock, and mezcals from this region often carry a briny, almost oceanic finish that sets them apart. The primary agave species is Agave salmiana, a large, cold-hardy plant adapted to the arid highland plateau of north-central Mexico.
Durango, contributing about 1.4% of national production, sits in the rugged northwest and works primarily with species suited to its drier, more extreme climate. Tamaulipas and Zacatecas round out the northern producing states, each with small but culturally significant traditions. These northern mezcals tend to be less well known internationally but are increasingly reaching export markets as demand grows.
Puebla, Michoacán, and Smaller Producers
Puebla accounts for 3.3% of national mezcal production, making it the second-largest producer by volume after Oaxaca. Michoacán contributes about 1.2%, and Guanajuato, the State of Mexico, and municipalities in other authorized states add smaller amounts. Each region works with different agave species and production styles shaped by local tradition and environment.
Michoacán is notable for its use of both cultivated and wild agave in volcanic highland terrain. The State of Mexico, the newest entrant to the denomination, is still establishing its identity in the mezcal market. Across all these smaller producing regions, output is typically artisanal, with family-run operations using methods passed down through generations.
How Geography Shapes Flavor
The wide geographic spread of mezcal production is exactly what makes the category so diverse. Altitude, soil composition, water source, and local agave species all interact to create what producers call terroir. A mezcal from the limestone-filtered springs of San Luis Potosí tastes fundamentally different from one made with tropical rainwater in Guerrero’s lowland valleys or mineral-rich volcanic soil in highland Oaxaca.
High-altitude sites, where temperatures swing dramatically between day and night, tend to produce agaves with more complex sugar profiles. Wild agave species that grow in these conditions, like Tepeztate, develop flavors that simply cannot be replicated elsewhere. Agave ecologist Dr. Ana Valenzuela has warned that losing wild agave populations means losing centuries of flavor history, since some profiles could vanish entirely if the plants disappear from their native habitats.
Where Most Mezcal Ends Up
About 70% of all mezcal produced in Mexico is exported, with the United States receiving 74% of those exports. Domestic Mexican consumption accounts for roughly 30% of total production volume. Oaxaca’s dominance in production means that the vast majority of mezcal available on shelves in the U.S. and Europe originates from that single state. Bottles from Guerrero, San Luis Potosí, or Durango are rarer and often positioned as specialty products, prized for their regional character and the wild agave varieties unique to their landscapes.
