The alcohol content by weight of regular Budweiser beer is 3.92 percent; the alcohol content by volume is 4.99 percent. The content of the beer is usually around 5.5 percent before it is weakened with the addition of water.
Budweiser, and its parent company, Anheuser-Busch, is a company that came under fire for the addition of water to its beer. Customers and agencies that are representative of customers accused the company of changing the formula to make the beer and adding water to make it less effective and less alcoholic. When National Public Radio investigated the content of the beer, they came up with the same results that are listed on the outside of the can.
To be considered beer in the United States, the beverage has to have an alcohol content that lies somewhere between 2 and 12 percent. Manufacturers of alcohol are expected to clearly print the type of beverage that the product is on the outside of the container. They are also expected to put an accurate percentage of the alcohol content on the container. Budweiser printed the amount of alcohol by volume on the outside of their containers and it matched up with the the amount of alcohol in the beverage when tested by an independent agency.
