The lawsuit was filed Thursday in Wisconsin federal court but the feud between the country’s two largest brewers began when Anheuser-Busch aired commercials making the corn syrup claim during this year’s Super Bowl .
Corn syrup is a fermentation aid used by several brewers , including Anheuser-Busch and MillerCoors. But no corn syrup remains in the beers once fermentation is complete.
Chicago-based MillerCoors says Anheuser-Busch is preying on health conscious consumers who have negative connotations of corn syrup, sometimes confusing it with the high-fructose corn syrup in sodas. MillerCoors wants a judge to order Anheuser-Busch to stop the ads.
Anheuser-Busch says it stands by its campaign and won’t change it.
