Budweiser is an American-style pale lager produced by Anheuser-Busch, currently part of the transnational corporation AB InBev and produced in various breweries around the world. There is an unrelated lager also called Budweiser, originating centuries ago in České Budějovice, Czechia (historically known as Budweis); the existence of the two separate beers has given rise to a trademark dispute preventing Anheuser-Busch from using the “Budweiser” name in some regions, leading to the exclusive use of “Bud” in those markets.
Introduced in 1876 by Carl Conrad & Co. of St. Louis, Missouri, Budweiser has become one of the largest-selling beers in the United States. The lager is available in over 80 countries, though not under the Budweiser name where Anheuser-Busch does not own the trademark. Budweiser is a filtered beer, available on draft and in bottles and cans, made (unlike the Czech lager) with up to 30% rice in addition to the hops and barley malt used by all lagers.
