A half-pint compared to megabrewers like the world's #1 beer maker Anheuser-Bush InBev, The Boston Beer Company holds a distinction all its own -- it is the US's largest craft brewer. The company produces more than 50 seasonal and year-round varieties of craft beers at breweries in Boston and four other states. Annually, it sells around 4.2 million barrels of lagers and ales (including its flagship Samuel Adams Boston Lager and other Sam Adams brand beers), and Twisted Tea malt beverages. it also brews beer for third parties. Founded in 1984 by its chairman James Koch, The Boston Beer Company has grown along with America's increasing thirst for better beer.
