The Chancellor's announcement adding 1p duty to the price of beer was criticised by real ale drinkers today.
The Campaign for Real Ale (Camra) said the increase amounted to a double blow, following price rises by several brewers and pub companies last month.
Mike Benner, chief executive of Camra, said, "This is a disappointing Budget for beer drinkers.
"This increase is a blow which will hit pubs, and consumers hard.
"A penny may not sound like much, but today's tax rise follows recent wholesale beer price rises by some brewers.
"Some pubs will now be charging as much as 10 pence a pint more than they were only a month ago.
"At a time when beer consumption is falling and pub-going is in decline this is a potentially devastating outcome for consumers and hard-working licensees."
Mr Benner added: "A tax rise is a flawed strategy which will cost jobs, increase smuggling and uncontrolled drinking and leave responsible beer drinkers out of pocket."
Gordon Brown's decision to raise beer duty was also attacked by Britain's brewers.
"It is very disappointing that Gordon Brown continues to choose a tax strategy that favours imported Australian chardonnay over home produced British beer", said Mark Hastings, director of communications at the British Beer & Pub Association.
