The Campaign for Real Ale has written to the Chancellor urging him to get rid of duty on beers that have an abv of 2.8% or below.
The consumer group also said Alistair Darling should end the special treatment of spirits to fund a reduction in beer duty.
Last year’s pre-Budget report saw excise duty on beer, wine and cider increase by 8% whilst spirits saw a rise of 4%.
Chief executive Mike Benner said: “UK beer duty has been increased by 52% since the current Government came to power in 1997 whilst spirit duty has increased by only 19%.
“The 4% duty concession given to the spirits lobby following last year’s pre-Budget report should be withdrawn to fund a fair deal for beer.
“In the longer term, the difference in the duty rate for spirits and lower alcohol categories should be restored to the levels that Labour inherited when they came to power in 1997.”
