History of beer in Mexico dates from the Spanish conquest of the Aztec Empire. While Mesoamerican cultures knew of fermented alcoholic beverages, including a corn beer, long before the 16th century, European style beer brewed with barley was introduced with the Spanish invasion soon after Hernán Cortés's arrival. Production of this beer here was limited during the colonial period due to the lack of materials and severe restrictions and taxes placed on the product by Spanish authorities. After the Mexican War of Independence, these restrictions disappeared, and the industry was permitted to develop. Furthermore, the arrival of German immigrants and the short-lived empire of Austrian Maximilian I in the 19th century provided the impetus for the opening of many breweries in various parts of the country. By 1918, there were 36 brewing companies, but over the 20th century, the industry consolidated until today, only two corporations, Grupo Modelo (now owned by AB InBev) and Cervecería Cuauhtémoc Moctezuma formerly known as FEMSA Cerveza (now owned by Heineken) control 90% of the Mexican beer market. This industry is one of the most prevalent in the country, with over 63% of the population buying one brand or another. Beer is also a major export for the country, with most going to the United States, but is available in over 150 countries worldwide. History 16th century to 19th century Prior to the Spanish conquest of what is now Mexico, there had been fermented alcoholic beverages in Mexico. The best known of these is pulque, which is the fermented sap of the maguey or agave plant. More similar to beer is a lesser-known beverage, called tesgüino or izquiate, brewed by various cultures. This is made from fermented corn, and creates light, amber-colored liquid which is whisked before drinking. Tesgüino can still be found in Mexico today, mostly homemade, in the north and west of Mexico in states such as Chihuahua, Sonora and Colima. Among the Tarahumaras, the drink is used for rituals. A similar beverage, called pozol, is made in Oaxaca, Chiapas and Tabasco with corn and cocoa beans. Beer brewed with grain such as barley was produced in small quantities by Hernán Cortés’ soldiers, but it was limited due to the lack of supplies. The first official concession to brew European-style beer was granted to Alfonso de Herrero in 1543 or 1544. Its exact location is unknown, but it is thought to have been
