Industrias La Constancia, El Salvador's largest brewer and bottler of purified water, dominates the Salvadoran export market of beers and bottled water. The company became part of the second largest brewer in the world, SABMiller, in 2005. Its flagship brand is Pilsener, a pilsner style lager beer, the national beer of El Salvador. In 2011, La Constancia centralized its operations and opened its new headquarters in San Salvador, where it moved in 1928 from the Santa Ana Department. The company produces the Agua Cristal brand of bottled water, the best selling in El Salvador and in the Central American region. The Coca-Cola company uses the La Constancia installations to manufacture its beverage brands sold in El Salvador and the rest of Central America.
