 The most expensive beer in all of Major League Baseball can be found right here in D.C. A beer can cost as much as $15 at Nationals Park, according to data from Statista. That's about $4 more than the highest-priced beer in Fenway Park, Wrigley Field, or Camden Yards. At Core Field in Colorado, a beer is just $3. Some Nats fans say they drop more than $1,000 on beer alone over the season.
