Danish brewer Carlsberg said adverse currency movements and a lack of sales growth in its Russian markets had dented first half profit.

To June 30 operating profit fell 31% to DKK1.25bn from DKK1.8bn. Sales dropped 7% to DKK16.3bn.

Carlsberg blamed an “overall economic uncertainty” for the unexpected drop in beer consumption.

In the UK, the Carlsberg brand achieved a 5% gain, while Tetley’s “maintained volume” in the decreasing ale market. Operating profit was down due to increased costs for marketing, restructuring and pensions, the company said.
