Budweiser is an American-style pale lager, part of AB InBev. Introduced in 1876 by Carl Conrad & Co. of St. Louis, Missouri, Budweiser has become a large selling beer company in the United States.
Budweiser may also refer to an unrelated pale lager beer, originating in České Budějovice, Czech Republic (in German, Budweis) produced by the Budějovický Budvar brewery. The parallel existence of two separate brands with the same name has given rise to a series of trademark disputes between them. Usually, either Anheuser-Busch or Budějovický Budvar are granted the exclusive use of the Budweiser name in a given market. Anheuser-Busch commonly uses the Bud brand for its beer when Budweiser is not available. The AB lager is available in over 80 countries, though not under the Budweiser name where Anheuser-Busch does not own the trademark. AB 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 common to lagers.
