The Chancellor was said to be the toast of brewers, pubs and drinkers after announcing a 1p cut in the price of a pint for the second year running.
The industry said the move will protect 7,000 jobs, mainly of younger people working in pubs and bars.
Brigid Simmonds, chief executive of the British Beer and Pub Association, said: "This is fantastic news, and George Osborne is again the toast of Britain's brewers, pubs and pubgoers.
"It also shows that the Government has understood our case, that taxes on British beer had become far too high, and action was long overdue.
"I hope this becomes a trend in future budgets for this British-made, lower-strength drink."
Mike Benner, chief executive of the Campaign for Real Ale (Camra), said: "Camra is delighted to see the Chancellor implementing an unprecedented second consecutive cut of 1p in beer duty. This is not only about keeping the price of a pint affordable in British pubs but helping an industry which has been in overall decline continue on its long road to recovery.
"Camra cares greatly about the future of the great British pub and it is clear from this Budget announcement that the Government do too.
"No doubt many of our 160,000 members will be raising a glass to the Chancellor this evening to toast another brilliant Budget for British beer drinkers."
