Pulque de Tlaxcala, a protected geographical indication since 2026: what the name now requires

On February 24, 2026, Mexico's official gazette, the Diario Oficial de la Federación (DOF), published a declaration by the Mexican Institute of Industrial Property (IMPI) that protects "Pulque de Tlaxcala" as a geographical indication. IMPI's director general, Santiago Nieto Castillo, signed it in Mexico City on February 10, 2026. The declaration ties the name to a zone of 25 municipalities in the state of Tlaxcala, and it took effect on the first business day after publication, which by our count was February 25.

Pulque is the fermented drink of the maguey. The declaration defines it as an alcoholic beverage of pre-Hispanic origin, made by fermenting aguamiel, the sap collected from the maguey pulquero, Agave salmiana. It credits Tlaxcala's pulque with a slightly thicker consistency, which it puts down mainly to dextrans that Leuconostoc bacteria make while the sap ferments.

Where the name applies

The protected zone is a list of municipalities, all in Tlaxcala state: Apizaco, Atlangatepec, Atltzayanca, Calpulalpan, Chiautempan, Contla de Juan Cuamatzi, Españita, Huamantla, Hueyotlipan, Ixtacuixtla de Mariano Matamoros, Muñoz de Domingo Arenas, Nanacamilpa de Mariano Arista, Panotla, San José Teacalco, Sanctórum de Lázaro Cárdenas, Teolocholco, Terrenate, Tetla de la Solidaridad, Tlaxcala, Tlaxco, Tocatlán, Tzompantepec, Xaloztoc, Xaltocan and Yauhquemehcan. The agriculture ministry, SADER, notes that the list includes the state capital, Tlaxcala.

The declaration also says where the drink is sold. Its main local markets, it says, are Nanacamilpa, Atltzayanca and Calpulalpan. Within Mexico it names Puebla, Mexico City, Querétaro, Guanajuato, San Luis Potosí, Jalisco, Michoacán, Veracruz and the State of Mexico, among others, and abroad a list of countries that starts with the United States, Spain and Japan. It links the drink's recent growth to the boom in food tourism, which in its account took pulque from local pulquerías and public markets to audiences around the world reached through digital platforms, and won it young new drinkers.

How the declaration describes the making

The text sets out the traditional method step by step. First the plant is capado: its central bud, the meyolote, is cut out so that the maguey stops flowering and stores sugar, leaving a hollow where the sap will gather. After a rest of months comes the raspado, the scraping of the hollow's walls with a thin steel tool; the declaration says the pressure the worker applies determines both how much aguamiel follows and its quality. A few days later the sap starts to flow. The tlachiquero draws it out by suction with an acocote, originally a long gourd, and carries it in containers called castañas, which the text says are still loaded on donkeys, to the tinacal, the room where it ferments.

Fermentation is started with semilla, a portion of pulque already fermented, and kept going by adding fresh aguamiel as each batch "cuts" (our translation of "cortar"). The declaration describes the aroma it expects: freshly baked bread and yeast, with notes of the maguey the sap came from.

What it takes to use the name

The declaration calls the name national property. It may be used only with an authorization from IMPI, which the institute issues once a body responsible for certifying compliance with the product's rules of use has been accredited, and once the user meets the requirements of the Federal Law for the Protection of Industrial Property. Anyone authorized must use the name exactly as the declaration writes it and mark the product with the words "Indicación Geográfica Protegida" or the initials "I.G.P."

The product itself must follow rules of use filed on October 15, 2025, which set its characteristics and specifications, together with the official standards that apply to it. A change to those rules counts against third parties only once it is registered with IMPI.

SADER summed it up in its article of March 4, 2026: "No todo lo blanco es pulque", or "not everything white is pulque" (our translation). Its article explains that the name now depends on two things: production inside a defined part of the state, and certain traditional practices.

Geographical indication or denomination of origin?

Mexico protects regional products under two similar labels, and IMPI's own explainer, posted in 2018 under the law then in force (the pulque declaration rests on a law published in 2020), sets out the difference. A denomination of origin covers a product whose quality or characteristics are due exclusively or essentially to its geographic setting, natural and human factors included. A geographical indication covers a product with a quality, reputation or other characteristic that is mainly attributable to where it comes from. The tie to the place is stronger for a denomination of origin, IMPI says, while a geographical indication needs to meet only one criterion linked to its origin.

Tequila is the best-known example of the stronger label. Its regulatory council says the general declaration protecting the denomination of origin was published in the DOF on December 9, 1974, and calls it the first of the 18 that Mexico has today. Our guide to tequila and mezcal labels explains how those spirits are certified.

Where things stand

The DOF's record of the declaration, read on November 11, 2026, says it remains in force for as long as the conditions that led to it continue, and that only another IMPI declaration can end it. Its terms can be changed at any time, by IMPI itself or at the request of an interested party, following the procedure in the industrial property law. IMPI is also to seek international recognition of the name under the trade treaties and agreements Mexico has in force.

Neither the declaration nor SADER's article names the certifying body that has to be accredited before IMPI can authorize users of the name.
