Consumer advocates say the government needs to add more details to labels being planned for alcoholic drinks.

The National Consumers League said the Treasury Department's proposal should include the amount of alcohol per serving, the definition of a standard drink and U.S. dietary guidelines on drinking.

A proposed label rule released by the department last July includes the amount of alcohol by volume, calories, carbohydrates, fat and protein contained in a standard serving size.

Alcohol trade groups are split over expanding the label information. The Distilled Spirits Council favors two of the additions while both beer and wine groups say the labels could mislead consumers.
