We know that the thought at the forefront of your mind while downing a shot of whiskey is “How many calories are in this?” It’ll be a lot easier to figure out now when drinking brands like Johnnie Walker, Guinness, Smirnoff and Baileys, as parent company Diageo announced today it’ll include nutritional information on its products’ labels.

The U.S. Alcohol and Tobacco Tax and Trade Bureau gave companies the go-ahead to include information like calories, carbohydrates, fat and protein content on booze labels on 2013, but it’s a voluntary thing.

Diageo said in a statement Thursday that all its brands will display per serving nutritional information on drink labels, and has gained approval for the label on its U.S. products from the bureau.

“Consumers are increasingly discerning about what’s in their glass,” Diageo Chief Executive Officer Ivan Menezes said in the statement. “We are committed to ensuring our consumers have the best possible information from which to make informed choices.”

The company says it’s the first one to voluntarily disclose nutritional information on alcoholic drinks, and it could be a good way to stay in tune with the consumer trend of disclosing what exactly is in the products we’re eating and drinking.
