The usual laws of economics don't seem to apply to beer. More producers should lead to more competition for the same amount of drinkers and lower prices for consumers.
But lately, prices keep on rising, and as long as people keep on buying that trend will continue.
Nationwide though, beer is losing market share to spirits and wine, this could be a result of higher and higher beer prices.
There do seem to be a lot of sale prices around here being offered, but maybe that's just the usual summertime activity, I only noticed it because the Rolling Rock was $8.99 for 18, and I used to drink it years ago.
