Editor of Budweiser Beer Water Mixing Event

A complaint filed by two American consumers in the federal court of Philadelphia, Pennsylvania, USA, Anheuser-Busch Company (hereinafter referred to as Budweiser), a subsidiary of Budweiser InBev, in St. Louis, Missouri, adulterated the finished beer. The plaintiff believes that Budweiser's behavior violates the provisions of state laws on consumer protection.

The plaintiff's lawyer said that these lawsuits were based on information provided by former employees of Budweiser Brewery. These employees broke the news that this practice is a "hidden rule" and the purpose is to save costs. The process of adding water is completed at the time of bottling. After adding water, the taste of Budweiser beer is diluted. They disclosed that Budweiser mixed water into the wine before bottling, which reduced the alcohol content by 3%-8%.

Budweiser issued a statement on March 27th, denying the allegations. Peter Kramer, the company's vice president in charge of brewing and supply business, issued a statement on the 27th, saying that the allegations against Budweiser were "completely false" and that these lawsuits were unfounded. "Our beer fully complies with all laws on alcohol labeling. We always insist on brewing beer with the highest standards. This is why our beer sells well in the United States and other countries. " Kramer said.

China consumers asked Budweiser to confirm whether its products sold in China market also had the phenomenon of water adulteration accused by American consumers, but the other party did not respond positively to this, only saying that "our quality commitment is applicable to the whole world".
