The British Beer and Pub Association (BBPA) has urged tax relief for brewers to enable the sector to help lead Britain to an export-led recovery from recession.
New Government figures show an "impressive leap" in Britain's beer exports and BBPA chief executive Brigid Simmonds has said now is not the time to load extra tax burdens on British brewers.
Beer exports were up 24% in 2010, increasing in value to £544m, according to HM Revenue & Customs export data. The rise equates to 230 million extra pints of exported beer.
The BBPA is warning that Government is planning "huge" beer tax rises in the 23 March Budget.
"These huge increases in beer exports are something to proud of," said Simmonds. "There is nothing to match the unique taste and variety of British beer, and overseas beer drinkers clearly have a growing taste for it.
"With UK exports so vital to our economic recovery, the huge growth in the number of breweries in Britain means we are sowing the seeds now for the British export champions of the future.
"However, punitive new taxes from the Government, which plans a 7% tax in beer duty this March, will hold us back. We need a climate that encourages the innovation and investment that will ensure future export growth.
"Huge rises in beer taxes will have the opposite effect."
