Originally called 'Siglo XX' - 'siglo' is Spanish for century and the two 'X' Roman numerals represent the beer being named to commemorate the new, as then 20th, century. The modern Dos Equis name means 'two Xs'. First brewed in 1897 by a German brewer who established the Moctezuma brewery in Veracruz, Mexico in 1884.
In 2016, Dos Equis replaced Goldsmith with the French actor Augustin Legrand, as a younger, but supposedly equally interesting version of "the man." It didn't take. AdAge reported Wednesday that sales of Dos Equis have slumped and the brand is retiring the character—and Legrand with it.
