Miller Brewing Company officials say they have no plans to pull the Sparks alcoholic energy drink from store shelves or even to review the marketing strategy for the product, Beverage Daily reported July 1.

"The brand and its labeling have received approval from the federal government," said Miller spokesperson Julian Green. "While we continue to work with authorities on this issue, as well as our own responsible drinking initiatives, we are also protecting our right to innovation."

With Anheuser-Busch's recent decision to remove ingredients like caffeine and guarana from its Tilt and Bud Extra products, pressure has increased for Miller to drop or modify Sparks, the leading alcoholic energy drink on the market. Advocates contend that the drinks appeal to underage consumers and pose unacceptable health risks.

Green said that Miller would continue to work with retailers to limit confusion of Sparks with nonalcoholic energy drinks. "On the actual product packaging itself, we mention that it contains alcohol at least four times on the label," he said. 

Steve Gardner, litigation director for the Center for Science in the Public Interest, warned that Miller "is lurching on very thin legal ice if they continue to market these dangerous drinks."
