Your beer cans and bottles are in for some big changes. The Beer Institute, an organization that represents the companies that make 81 percent of the beer in the U.S., said we’ll soon see calorie counts on some beer labels.

The institute expects its companies, which include the makers of Budweiser, Miller, and Coors beers, will change some labels immediately and all labels by 2020.

Most people on Twitter didn’t think the calorie labels would change their drinking habits, but the Center for Science in the Public Interest, offered a preview by posting the calorie counts for dozens of popular drinks, from light beers to restaurant cocktails. It shows that pre-dinner cocktail can cost you anywhere from a mere 50 calories to 780 calories.

Though beer enthusiasts might turn a blind eye to the labels, they are a way to keep consumers educated about what they’re chugging down.
