Unlike most early beers, which used only barley, hops, yeast and water, Budweiser is brewed using rice and Beechwood chips in addition to the four major ingredients. The Beechwood chips, according to Budweiser, creates a smoother taste, while rice has since been known to the beer world to produce a "clean finish". Rice is an ingredient utilized by many brewers because it is a less expensive ingredient than malted barley, rye, or other grains. Anheuser-Busch was also one of the few breweries during Prohibition that had the resources and financial wherewithal to convert to "cereal beer" production - malt beverage made with non-fermentables such as rice and unmalted barley and rye, and able to stay under the 0.5% limit established by the Volstead Act. Following the repeal of Prohibition in 1933, the major breweries continued to use unmalted cereal grains to provide the full body and mouthfeel of a "real" beer while keeping the alcohol content low.
