Mezcal Tosba

At a glance

Mezcal Tosba is a mezcal palenque (the small traditional distillery where mezcal is made) in San Cristóbal Lachirioag, a Zapotec village in the Sierra Norte of Oaxaca: the northern mountain range that ridges away from Oaxaca City toward Veracruz, ecologically and culturally distinct from the Central Valleys and Sierra Sur where most named Oaxacan mezcal originates. The brand was founded by two cousins, Elisandro González Molina and Edgar González Ramírez, after they returned to their village from years working in Silicon Valley in the late 1990s. They are the first commercial mezcaleros their village had ever produced.

The name Tosba is Zapotec for "just one", which the founders use as a one-word editorial position: one village, one family, one production method, no shortcuts. Production is artesanal, double-distilled in copper, governed by NOM-070-SCFI-2016A regulatory-standard NOM is a federal Mexican product norm. Unlike facility NOMs (4-digit identifiers of specific distilleries), a standard NOM defines the rules for an entire category of product: which raw materials are permitted, where the product may be made, how it must be processed, and how the bottle must be labeled. Standard NOMs are written as "NOM-XXX-SCFI-YYYY" where XXX is the standard number and YYYY is the year. NOM-070-SCFI-2016 (Mezcal). The official Mexican standard for mezcal production. Defines three production tiers (Mezcal Industrial, Mezcal Artesanal, Mezcal Ancestral) with specific equipment and method requirements for each, lists the permitted agave species and states, and governs labeling. Enforced by the Consejo Regulador del Mezcal (CRM).. The palenque runs its own agave nursery for reforestation and the house holds Bat Friendly certification (the third-party program that verifies a producer allows a percentage of its agave to flower so bat pollinators can feed and propagate seed across the landscape, instead of cutting every plant before it bolts).

A Zapotec return story

Elisandro and Edgar were among the generation of young Zapotec men from the Sierra Norte who left their villages for the United States during the migration waves of the 1980s and 1990s, ending up working service and tech-adjacent jobs in the San Francisco Bay Area. They came home around the turn of the 2000s with the same question many returning migrants face: what was worth building in the village they had left. The answer they arrived at was mezcal. Neither cousin came from a mezcalero family. The Sierra Norte, unlike Santiago Matatlán or San Luis Amatlán, does not have a centuries-deep palenque-on-every-block density. The cousins learned the craft by traveling to other mezcal-making villages, apprenticing where they were welcomed, and then building their own palenque in San Cristóbal Lachirioag from scratch.

Sierra Norte as a terroir distinct from the Valles and the Sur

Most of the named Oaxacan mezcal that ships internationally comes from one of two production landscapes: the Central Valleys (Santiago Matatlán, Tlacolula, San Dionisio Ocotepec) and the Sierra Sur (Miahuatlán, Sola de Vega, San Luis Amatlán). The Sierra Norte is the third Oaxacan mezcal landscape, and a less travelled one. Its mountains run higher and wetter than the Valles. The agaves on Tosba's slopes grow at elevations where colder nights stretch out the maturation curve and the species mix is shifted: the karwinskii complex of the Valles is sparser here; Tobalá (Agave potatorum) and Tepextate (Agave marmorata) wild populations sit in the rocky ledges; and Espadín (Agave angustifolia) cultivated in highland Zapotec smallholder plots is the everyday baseline.

The flavor consequence the Tosba bottles tend to read: a cleaner, drier, more mountain-mineral character than the broader, wetter, more campfire-smoke profile of Valles espadín; aromatics that lean toward dried herb, cold stone, and forest floor more than they lean toward caramelized agave fiber. Bottles are not blends across regions; they are single-village Sierra Norte expressions, full stop.

The production method

The palenque runs the standard artesanal Oaxacan workflow with one or two practical refinements the cousins built in as they learned the craft. Agave is cooked in an in-ground stone pit oven fired with driftwood and biomass rather than the freshly cut hardwood that most palenques in the Valles burn through; the fuel choice is a sustainability practice the brand publicly emphasizes. Cooked piñas are crushed by tahona (the limestone wheel pulled by a horse or donkey that has crushed agave on Oaxacan palenques for generations) or by hand, depending on the batch. Fermentation runs in wooden tinas (the open wooden vats used across the artesanal mezcal tradition) with wild airborne yeasts: no cultured strains, no commercial yeast. Distillation is double, in small copper alambiques, the configuration NOM-070-SCFI-2016A regulatory-standard NOM is a federal Mexican product norm. Unlike facility NOMs (4-digit identifiers of specific distilleries), a standard NOM defines the rules for an entire category of product: which raw materials are permitted, where the product may be made, how it must be processed, and how the bottle must be labeled. Standard NOMs are written as "NOM-XXX-SCFI-YYYY" where XXX is the standard number and YYYY is the year. NOM-070-SCFI-2016 (Mezcal). The official Mexican standard for mezcal production.

The in-house nursery and Bat Friendly certification

Two of Tosba's editorially distinctive practices intersect at the same problem: the long-term ecological cost of artisanal mezcal's commercial growth.

The nursery. The palenque runs an on-site agave nursery where the founders raise seedlings for replanting on their own slopes and on the slopes of neighboring families who supply piñas. The point is straightforward: a maestro mezcalero who only harvests is mining the landscape; a maestro who also propagates is rebuilding it. Few small palenques run their own seed and seedling program at this discipline.

Bat Friendly Tequila and Mezcal. The certification, run by a coalition of agave ecologists (Rodrigo Medellín's group at UNAM is the most visible scientific anchor), recognizes producers who let a measurable percentage of their agave plants flower fully rather than cutting them when the quiote (the giant flowering stalk that signals end-of-life sugar concentration) first emerges. Letting an agave flower destroys the piña for spirit production (the sugar runs upward into the stalk and out to the flowers), so it is a real economic cost. The reward is that bats (the genus Leptonycteris, principally the lesser long-nosed bat L. yerbabuenae) can feed on the flowers, transfer pollen across kilometers of landscape, and produce genetically variable seed instead of the clonally identical hijuelos that dominate cultivated agave. Tosba is on the certified-producer list.

The expressions

The Tosba lineup centers on single-agave bottles rather than blends; the labels rotate with what the slopes produce in any given season.

• Tosba Espadín (Agave angustifolia): the everyday baseline, made from cultivated Espadín on the cousins' own and neighboring slopes. The Sierra Norte highland-cool maturation curve and the wild-yeast wooden-tina ferment produce a cleaner, drier, more mineral espadín than the typical Valles bottle.
• Tosba Tobalá (Agave potatorum): the small wild rosette agave that grows from seed on rocky ledges and takes 10 to 12 years to mature. The Sierra Norte populations are not the most commercially exploited Tobalá range (Sola de Vega and San Luis Amatlán are), which makes Tosba's bottle a useful tasting reference for what the species reads like at higher elevation.
• Tosba Tepextate (Agave marmorata): a long-clock wild agave that takes 25 to 35 years to build harvestable sugar. The Tosba release is among the small group of single-village highland Tepextates on the US market.
• Tosba Cuixe (Agave karwinskii): a trunked karwinskii expression from the Sierra Norte's sparser karwinskii populations; the bottle reads more austere and herbal than its Valles counterparts.
• Tosba Pechuga: a seasonal release in which a basket of fruits and a raw breast (the traditional Oaxacan technique that suspends an aromatic load in the still during the second distillation; the meat absorbs fats and the fruits and spices contribute aroma) is hung over the second-pass charge. Pechuga production is occasional and small-batch, and the recipes shift season to season.

Where Tosba sits in the mezcal landscape

Tosba is not the multi-maestro portfolio model of Mezcal Vago, the single-house Sierra Sur dedication of Lalocura, or the scaled-modern sustainability messaging of Wahaka. It is the founder-operator, single-village, Sierra Norte highland-terroir house, run by two cousins who chose to come home and built a palenque from scratch in a village that had not had one before. The brand's editorial value sits in two places at once: as a way to taste Sierra Norte mezcal alongside Valles and Sierra Sur bottles in a serious flight, and as a working example of what an artisanal mezcal palenque looks like when ecological discipline (the nursery, the driftwood fuel, the Bat Friendly certification) is built into the model from the founding day rather than retrofitted later for marketing.
