Budweiser, popularly referred to as Bud or sometimes Bud Heavy to distinguish it from Bud Light, is the primary brand of beer made by Anheuser-Busch. Budweiser is a pale lager made with a proportion of rice as a substitute adjunct for barley malt, for which it has received some criticism, though the company takes the position that the rice gives the beer a lighter taste. Bud is produced in various breweries located around the United States and the rest of the world. It is a filtered beer available in draught and packaged forms.

The Budweiser bottle is a familiar icon to most Americans. The bottle has remained relatively unchanged since its introduction in 1876.
