While Mesoamerican cultures knew of fermented alcoholic beverages, including a corn beer, long before the Spanish conquest, European style beer brewed with barley was introduced with the Spanish soon after Hernán Cortés’s arrival.

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 and FEMSA 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 in the world.
