 8.54. The most expensive beer in all of Major League Baseball can be found right here in D.C. A beer can run you as much as $15 at Nationals Park. That's according to data from Statista. It's about $4 more than the highest-priced beer at Fenway Park, Wrigley Field, or Camden Yards. At Coors Field in Colorado, the home, of course, of Coors beer, that cold, frosty one will only run you $3.00.
