Greene King has announced that Harvey's Best Bitter will go on sale again in the Lewes Arms in Sussex this week.
The beer was removed from sale in December last year by the Suffolk brewer and pub operator which owns the pub.
Lewes residents had led a four-month campaign to boycott the pub until Harveys was reinstated.
New local pubs managing director Jonathan Lawson decided the beer was to return following an internal review.
"We are passionate supporters of cask beer, are proud of our own brews and have recognised the intensity of feeling around Harveys at the Lewes Arms," said Lawson.
"Now that Harveys is going back into the pub, my team and I are hoping that we can make a fresh start with our customers and are looking forward to helping the Lewes Arms once again play a full role in the local community."
Greene King chief executive Rooney Anand added: "The Lewes Arms is a very special local pub with a unique place in the life of the town.
"We underestimated the depth of feeling and level of reaction about our initial decision and I believe that the conclusion the team put forward to return Harveys to the bar is the right one. I'm pleased that Jonathan and the team have taken on board our customers' feedback and hope people will be pleased with the news."
