Six of America’s brewers, including three of the largest, will start posting nutritional information on all containers for sale by 2020. Pro Agriculture says three of the bigger brewers involved include Anheuser-Busch, Heineken USA, and Miller-Coors. The Beer Institute is the trade group that represents the nation’s largest brewers, and they’ll voluntarily begin applying labeling standards in an industry that has largely avoided increasing consumer demand for more nutrition information. The other three breweries include Constellation Brands Beer Division, the Craft Brew Alliance, and North American Breweries. Together with the other three, they produce around 80 percent of the beer consumed by Americans each year. The beer makers will identify ingredients on bottling, another part of the package, or on websites. Beer containers will also carry freshness dates. The labeling move is “an effort to get in line with where consumers are,” said Craft Brew CEO Andy Thomas.
