LONDON—Nutritional labeling on alcoholic drinks could become the norm after four of the world’s biggest brewers backed plans to add calorie counts to their products in Europe—and the U.S. potentially is their next stop.

The Brewers of Europe, a trade body representing beer makers across the continent, said members soon would begin listing nutritional information on their brands. Anheuser-Busch InBev SA, SABMiller PLC, Heineken NV and Carlsberg A/S were among those to endorse the proposal, and some would start as early as Thursday.

Alcohol producers are coming under pressure to follow the food industry by providing more detail on nutrition, especially in developed markets where consumers increasingly make health-based decisions. In 2014, 71% of Americans said “healthfulness” was a consideration when buying foods and beverages, up from 58% in 2010, says the International Food Information Council Foundation.

Diageo PLC, the world’s biggest alcoholic beverages company, last week said it would begin offering per-serving calorie counts on products including Smirnoff vodka and Guinness. Labels could hit stores in the U.S. within two months, it said.

Some beer companies already list nutritional information on their websites—SABMiller has done so since 2008—but the new plans commit the companies to providing uniform breakdowns for all products sold in the European Union, including calorie, fat, carbohydrate and salt content per 100 milliliters of liquid.
