Attorneys general in 27 states -- including Illinois -- are urging Anheuser-Busch (BUD) to issue warnings about mixing alcohol with caffeinated energy drinks.

"Spykes" is a two-ounce bottle of flavored malt beverage meant to be mixed with beer or other drinks, or consumed as a shot.

The St. Louis-based maker of Budweiser and Bud Light rolled the product out broadly last year.

In a letter to the company, state officials accused the beer company of marketing Spykes and other products to underage drinkers and failing to deter minors from using them.

Spykes comes in four flavors -- lime, mango, melon and hot chocolate. It measures 12 percent alcohol by volume, and also contains caffeine, ginseng and guarana.

The company rejects arguments that Spykes is marketed to teenagers.
