Craft brewers are accusing multinational beer giant Anheuser-Busch InBev of trying to crush them by buying up distributors then cutting off their access to store shelves, and the U.S. Justice Department is looking into those claims, Reuters reports, citing "three people familiar with the matter." In many states, breweries can't sell to the public without going through distributors. AB InBev has purchased five distributors in three states over the past few months, and the fast-growing craft brewing industry says that once the world's largest beer company is in charge, the smaller breweries start losing access to stores and their sales stagnate.
