Sales of draught beer and cider have fallen by 11.5% in the first four months of this year in pubs, according to figures from the Irish Brewers Association.
The statistics come as a number of leading brands have announced price increases in recent days.
The biggest fall in draught sales has happened in Dublin were turnover is down almost 15%.
Some major drink producers have confirmed they are increasing prices 4c per pint, citing higher costs as the reason behind the move.
Heineken, Guinness, Smithwicks, Carlsberg, Harp, Budweiser and Bulmers will all increase. It is expected the pubs will add a further 4c and two cent will go in VAT, meaning that a 10c increase is expected on their pints.
Today Beamish & Crawford, which produces Miller, Fosters, Beamish and Kronenbourg, said it was freezing prices in light of falling sales.
The company's chief executive Alf Smiddy said the price of a pint was becoming too expensive for consumers.
The Licensed Vintners Association welcomed the move and said its members were in a very difficult period.
