Polish brewers are suffering in more ways than one this year with predictions that beer sales could fall lower than last year's 66 litres per head according to local reports. It would be the first time since 1993 consumption has not registered growth. The report claims an increase in excise duty this year has halted expectations of continuing growth in beer sales over the next two to three years. Experts had previously predicted sales would see steady growth before stabilising at 75-80 litres per head.
