The Belgian brewer Interbrew announced today that it would be increasing prices of its German beer portfolio, as the effects of new German bottling laws and increased transport and raw material prices kick in.

The company said that hot weather had led to smaller wheat, barley and malt harvests, causing prices of the brewer's raw material to rise.

The company plans to raise wholesale prices of its Beck's, Haake Beck, Diebels and Dimix brands. There was no indication as to the extent of the price rises.

In January Interbrew raised the price of its beers in its domestic Belgian market by 2.5%, due to climbing malt prices.
