The average cost for a small draft beer at NFL games this season is $7.53, according to data collected by Team Marketing Report from each team. That's up from $7.05 in 2013.

The increase comes despite the introduction of a $4.50 beer in St. Louis, where the Rams now have the cheapest beer in the NFL. On the other hand, the fans of the Oakland Raiders and San Francisco 49ers must pay more than $10 for the cheapest beer at those games.

Of course, the $4.50 beer at Rams games and the $5 beers in other NFL stadiums are small sizes. If we consider the size of the beer, the most expensive beer is in Philadelphia, where the smallest beer costs 71 cents per ounce. The Cincinnati Bengals offer the cheapest beer per ounce, with a 14-ounce beer costing just $5 (36 cents per ounce).
