I would be cross too:
"It's absolutely outrageous that beer is getting even more expensive," Glutsch said, gulping down the last swig of his half-liter dark beer at lunch. "But there's nothing we can do about it — except drinking less and that's not going to happen."
The price of beer is going up in Germany due to the politics of global warming. Farmer's are giving up growing barley and are growing other crops used for biofuels. The effect has left a high demand for barley causing the price to double. Naturally everyone, including brewers must raise their prices to cover the costs.
This of course is what the global warming crowd would have us do: pay more for everything or forgo conveniences in the name of the environment and the children.
