From CNNMoney (Beer prices are going up ...):
Brewers across the globe are hiking prices to compensate for lower sales volumes and higher commodity costs.
Several things are going on here. First, rotten GDP (i.e., income) growth has reduced the demand for beer which reduces the amount of beer sold. This creates a surplus which should push prices down. Higher production costs has reduced the supply of beer which creates a shortage leading to a price increase. Ignoring the demand decrease (i.e., ignoring the silly "compensate for lower sales volumes"), prices will be rising because of higher production costs.
