Salmiana: the large maguey behind pulque and plateau mezcal

Salmiana (Agave salmiana) is used for pulque, mezcal and agave syrup. Aguamiel is the sweet liquid collected from a living maguey; the piña is its heart, which is harvested and cooked for mezcal. Large cultivated forms grow in central Mexican pulque fields, while spiny wild forms supply mezcal makers in San Luis Potosí.

Two harvests lead to two drinks

Both drinks begin with a mature agave. For pulque, a collector prepares the living plant’s center and gathers aguamiel. For mezcal, the piña is harvested, cooked, fermented and distilled.

Recognize the broad leaves and deep rosette

Salmiana’s fleshy leaves rise from a short or concealed stem. Younger central leaves stand upright; older leaves curve outward. Look along the concave blade for prominent marginal teeth and a substantial dark terminal spine. Green shades vary, sometimes with a gray-green bloom.

Large salmiana forms can grow taller than a person and several meters across. Their broad leaves commonly reach 1–2 m long and 20–35 cm wide. A fully grown quiote, the flowering stalk, can rise 6–8 m above the ground. Plant dimensions.

Two giant pulque plants with different leaves

A. mapisaga also grows into an enormous pulque plant. Its long, relatively narrow leaves and smaller teeth distinguish it from salmiana’s broad blades and stronger teeth. Cultivation changes the picture too: Hidalgo growers selected larger plants with reduced thorniness, abundant aguamiel and easier handling. Flora key, Hidalgo study (2021).

Pulquero describes a use; local names describe particular plants

“Maguey pulquero” can mean salmiana, mapisaga or another agave supplying pulque. Local growers distinguish plants more closely, and a name’s meaning can change between places.

Michoacán growers (2020), Hidalgo names, Table 2 (2019–2020 fieldwork), Derrumbes. The agave names guide covers other species and regional names.

Kew accepts A. salmiana Otto ex Salm-Dyck, first published in 1859, with subsp. salmiana, subsp. crassispina and var. ferox. Older studies use “var. salmiana” for the cultivated form; Kew now treats the flora’s subsp. tehuacanensis under var. ferox. Kew taxonomy, ferox synonyms.

Pulque fields and plateau mezcal country

Salmiana is native to Mexico. Pulque-growing communities in Hidalgo, Morelos and Michoacán cultivate it; wild mezcal plants occur in San Luis Potosí, including the studied populations of Aquiles Serdán, El Cuervo and Ipiña. Kew distribution, San Luis Potosí study (2016).

In Tehuacán–Cuicatlán, the large cultivated form grows around settlements and field boundaries, and in several vegetation types at 1,500–2,600 m. Beyond Mexico, Kew records introduced salmiana in the Canary Islands, the Cape Provinces of South Africa, Portugal and Spain.

Mature agaves for both drinks

Pulque and mezcal both use mature salmiana. Over years, the plant builds carbohydrate reserves in its piña, which it draws on to grow the quiote and flower. A mezcal maker harvests the mature piña; a tlachiquero removes the central growing point before the flower stalk develops and prepares the plant for aguamiel collection. Maturity and harvest timing.

The wait varies with the plant and growing conditions. Hidalgo growers reported 9–10 years for Xaminí and 12–13 for Mutá; Machetazo gives 10–12 years for its wild salmiana from Charcas, San Luis Potosí. Local age examples.

Collecting aguamiel and fermenting pulque

The tlachiquero, or aguamiel collector, removes the central growing point and prepares a cavity called a cajete. Scraping sustains the flow of aguamiel. Traditionally, a long gourd called an acocote draws out the liquid.

When we visited our friend Juan in Estado de México in October 2022, he collected aguamiel with a tube and a reused plastic bottle. The liquid had gathered in a cavity in the maguey’s center.

In Huitzilac, Morelos, Salvador Cueto, “Don Chava”, left prepared plants for five weeks before beginning twice-daily scraping and collection. One salmiana he managed had an estimated yield of about 335 liters of aguamiel over its full collection period. Huitzilac collection study.

Fresh aguamiel is sweet. Fermenting it with an active starter produces pulque: yeasts and bacteria turn its sugars into a milky, gently sour alcoholic drink with a viscous texture. In Tarímbaro, producers used sediment from the previous day’s pulque as a starter. Santiago Undameo producers briefly boiled the aguamiel, cooled it, then added their starter. Pulque fermentation, Michoacán practices.

Agave syrup from salmiana

Salmiana is also used to make agave syrup, alongside blue agave (A. tequilana). Fresh salmiana aguamiel can be heated to evaporate water and make a thick, sweet syrup. Our agave syrup guide explains this method, syrups made from harvested piñas, and their uses in drinks and cooking. Sources.

Cooking the piña for mezcal

Above ground steam cooking is traditional in San Luis Potosí and often gives its salmiana mezcals a less smoky profile. Machetazo and Derrumbes are two examples of the state’s salmiana mezcal. San Luis Potosí production · Regional history.

Machetazo’s wild salmiana from Charcas

Machetazo steam-cooks its Charcas salmiana in an above ground masonry oven, crushes it with a tahona, ferments naturally in masonry vessels and distills twice in copper. Its US expression is 45% ABV in a 700 ml bottle. The maker describes floral and citrus aromas, a silky texture and fresh jalapeño on the finish. Machetazo’s US sheet.

Manuel Pérez’s Derrumbes San Luis Potosí

For Derrumbes San Luis Potosí, Manuel Pérez uses wild A. salmiana subsp. crassispina from the Altiplano. The maker describes dry agave leaves and quiotes as fuel, and calls the mezcal floral and herbaceous with a touch of sweetness. Derrumbes’ account.

Salmiana’s small share of certified mezcal

Verde (A. salmiana) accounted for about 1.3% of the mezcal production reported by COMERCAM for 2025, compared with about 85% for espadín. COMERCAM’s 2026 report, page 7, Table 2.

Production shares use the report’s volume basis of 45% ABV, with blends listed separately. These figures do not estimate uncertified output.

Pulque work, cooking leaves and Hñähñu fiber

Pulque haciendas supplied Mexico City during the colonial period; railways expanded the trade in the nineteenth century. Ignacio Torres Adalid, known as “El Rey del Pulque”, led efforts to preserve the drink for transport as beer became a growing competitor. Escalante and colleagues (2016).

Salmiana also grows in living fences and supplies fiber and cooking leaves. Hidalgo growers described Corriente in fences and fiber work, and Mutá leaves used in barbacoa. In Ixmiquilpan, Hidalgo, Alicia Reyes Samilpa’s 2016 research records Hñähñu use of both salmiana and mapisaga leaf fibers for woven articles such as ayates. Hidalgo uses, Table 2, Reyes Samilpa’s fiber research.

Renewing a magueyal

Michoacán growers selected vigorous offsets, the young plants beside a parent, and transplanted them into their agave fields, or magueyales. Pulque plants rarely flowered because preparing the center for aguamiel collection prevents the flower stalk from developing. Michoacán study.

Wild plants bring a different management concern. A 2016 study of three San Luis Potosí populations of A. salmiana subsp. crassispina found substantial genetic variation within them and identified poorly managed extraction as a pressure. Allowing some mature plants to flower and set seed helps sustain that diversity. Wild salmiana study.

Questions about salmiana

Does “maguey pulquero” always mean Agave salmiana?

No. “Maguey pulquero” describes an agave used for pulque; salmiana, mapisaga and other species can supply it. In Hidalgo, Penca larga at El Cubo is mapisaga; Corriente penca larga at Rancho La Coyotera is salmiana.

Is salmiana mezcal always smoky?

No. Steam cooking is traditional in San Luis Potosí’s salmiana mezcal industry and often produces less smoky spirits. Machetazo’s Charcas expression is one example. CIATEJ regional history, pp. 180–181.
