MillerCoors took another swipe at Bud Light in a blog post that pointed to the rival beermakers' falling sales since it aired its Super Bowl ad that called out Miller and Coors' use of corn syrup in their lite beers.
Anheuser-Busch InBev bought 5½ minutes of air time for the 2019 Super Bowl, but it was a single 60-second commercial for Bud Light that made the biggest waves. The ad shamed Molson Coors Brewing's Miller Lite and Coors Light beers for using corn syrup, leading to backlash from farmers and MillerCoors, Molson's U.S. division.
After the ad aired, MillerCoors responded on Twitter and took out a full-page ad in The New York Times to hit back at Bud Light and defend its use of corn syrup.
Miller Lite and Coors Light use corn syrup to feed yeast in the brewing process. Once the yeast eats the corn syrup, it turns into alcohol and carbon dioxide. Anheuser-Busch uses rice to feed the yeast when it brews Bud Light.
The commercial also jeopardized an alliance meant to help the biggest U.S. beer producers. The Wall Street Journal reported that MillerCoors pulled out of a meeting scheduled this month with AB InBev, Heineken and Constellation Brands. The four beer companies had been discussing teaming up for a national ad campaign to revive U.S. beer sales for more than a year before the Super Bowl commercial aired.
