The world’s largest brewer has been accused of watering down beers, including Budweiser and Michelob, in lawsuits that seek millions of dollars in damages.

The suits, which have been filed against Anheuser-Busch InBev in Pennsylvania, California and other states, claim consumers have been cheated out of the alcohol content stated on labels.

The lawsuits are based on information from former employees at the company’s US breweries, according to lawyer Josh Boxer.

Anheuser-Busch InBev called the claims “groundless” and said its beers complied with labelling laws.
