PHILADELPHIA — Beer lovers across the U.S. have accused Anheuser-Busch of watering down its Budweiser, Michelob and other brands, in class-action suits seeking millions in damages.

The suits, filed in Pennsylvania, California and other states, claim consumers have been cheated out of the alcohol content stated on labels. Budweiser and Michelob each boast of being 5 percent alcohol, while some “light” versions are said to be just over 4 percent.

The lawsuits are based on information from former employees at the company’s 13 U.S. breweries, who said the 10 beers named in the lawsuit are watered down as a matter of corporate practice to save money, according to lead lawyer Josh Boxer of San Rafael, Calif.

The excess water is added just before bottling and cuts the stated alcohol content by 3 percent to 8 percent, he said.

Anheuser-Busch InBev called the claims “groundless” and said its beers fully comply with labeling laws.
