WASHINGTON -- After more than 30 years  of consideration, federal regulators finally have proposed that the licensed -beverage industry be required to list nutrition and alcohol-content labels on their containers, The Washington Post reports.

Hounded by consumer groups, the U.S. Treasury Department’s Alcohol and Tobacco Tax and Trade Bureau will mandate alcohol containers disclose carbohydrates, calories, protein, fat and alcohol content. The $160 billion alcohol beverage industry is split over how and where to list alcohol content.

Currently, the agency is recommending that the alcohol-by-volume statement could be put anywhere on the container, which would conform with an international trade agreement on wine. Right now, there is no standardized form for listing calories, ingredients or alcohol on beer, wine or liquor bottles.

Beer producers, in a letter to lawmakers, said that listing the alcohol per serving would be “complex, redundant and could mislead consumers.” Wine makers also oppose the ruling, saying that the testing required to list alcohol content would be costly. The new labeling rules would not be required until three years after a final ruling is published.
