Anheuser-Busch suing MillerCoors over Bud Light, Michelob Ultra recipes

MILKWAUKEE, Wisconsin — Anheuser-Busch is suing MillerCoors over its confidential recipes for Bud Light and Michelob Ultra.

In a heavily redacted court filing Thursday, Anheuser-Busch claims MillerCoors illegally obtained the recipes through one of its employees, who used to work for Anheuser-Busch.

Anheuser-Busch says MillerCoors wanted the recipes because it was planning to retaliate for Anheuser-Bush’s Super Bowl ads, which chided MillerCoors for brewing beer using corn syrup.

Anheuser-Busch seeks damages from MillerCoors.

The filing was the latest in a legal fight that began in March. MillerCoors sued Anheuser-Busch over the corn syrup ad campaign, which it says is false and misleading.

Last month, a federal judge in Milwaukee ruled in MillerCoors’ favor and ordered Anheuser-Busch to stop using packaging that implies rival contain corn syrup. Anheuser-Busch is appealing that ruling.
