The national lobbying group representing corn growers wasn't too sweet on Bud Light's Super Bowl ad Sunday touting how the beer is brewed without corn syrup.

".@BudLight America’s corn farmers are disappointed in you. Our office is right down the road! We would love to discuss with you the many benefits of corn! Thanks @MillerLight and @CoorsLite for supporting our industry," the National Corn Growers Association tweeted on Sunday.

The Bud Light spot centers around the mistaken delivery of a cask of corn syrup to the fantasy medieval Bud Light kingdom, a play on Budweiser's historical "King of Beers" tagline. The ad then follows efforts to return the ingredient to its rightful recipient — namely Bud Light competitors: Miller Lite and Coors Light.

The National Corn Growers Association later followed up with a another tweet, apologizing for using the wrong Twitter tag for Miller Lite. The original tweet also used the wrong tag for Coors Light.

The spot was not Bud Light's most discussed appearance during the game. The brand also featured in a crossover promotion with HBO's "Game of Thones," in which the Bud Light knight was killed by a dragon.

The New England Patriots defeated the Los Angeles Rams 13-3 on Sunday to win the franchise's sixth title under head coach Bill Belichick and star quarterback Tom Brady.
