London Brewer Fuller's has raised more than £2,000 for the Royal British Legion with cask sales of its Brewer's Reserve No 2.
The oak-aged ale is usually only served in bottles but it was made available in cask at this year's Great British Beer Festival.
Such was its popularity at the event at London's Earl's Court in August that the brewer has handed over a cheque for £2,138 to the Royal British Legion.
Director Richard Fuller said: "When we heard that The Royal British Legion was the official charity of the Great British Beer Festival we were very keen to play our part in raising money for such a worthwhile cause.
"We provided one firkin per day of the festival, and whenever it was made available for sale, a queue very quickly formed in front of the bar. Customers were thrilled that all proceeds were going to the Legion, a charity close to many people's hearts."
Michelle Campbell, Corporate Partnerships Manager at The Royal British Legion, said; "Fuller's support of our fundraising at the Great British Beer Festival was a very welcome addition to our plans and I am delighted that the beer made such an impact.
"To raise over £2,000 from just six barrels of beer is fantastic and I'm just disappointed I didn't get to try any at the festival before it all sold out."
