Corona is a brand of beer produced by Grupo Modelo in Mexico and exported to markets around the world. Constellation Brands is the exclusive licensee and sole importer of Corona in the fifty states of the United States, Washington, D.C., and Guam. Belgian company AB InBev owns the beer in all other worldwide markets and it solely brews the beer for all markets including the US. Corona is now brewed in China for the Australasia market. It is the top-selling brand of imported beer in the United States. It is often served with a wedge of lime or lemon in the neck of the bottle to add tartness and flavor. The recipe for the mash bill includes corn as well as the barley malt and hops traditionally used for making beer.
