Dos Equis is a historic and iconic Mexican beer brand founded in 1897 by German immigrant Wilhelm Hasse, who first brewed a beer called Siglo XX to mark the upcoming 20th century. The beer was later renamed Dos Equis, meaning "Two X's," inspired by the Roman numeral XX on the original label. It is produced by the Cuauhtémoc Moctezuma Brewery, a major Mexican brewery established in 1890 and now a subsidiary of Heineken International[1][2][4][5].

It benefits from the extensive distribution and production network of Cuauhtémoc Moctezuma Brewery, which operates multiple plants across Mexico with an annual production exceeding 30 million hectoliters[3][5].
