Carlsberg UK is claiming that its launch of a special edition Christmas cask beer signals its long-term commitment to the cask version of Tetley's.
Tetley's Northern Cracker is now available to the on-trade nationally.
CAMRA and beer lovers across the country have long expressed concerns that the closure of the Leeds site, expected in 2011, will mean brewing of Tetley's cask ale would wither and possible cease altogether.
But a statement from Carlsberg UK said: "This is the first piece of news in a major campaign for the Tetley's brand to be unveiled over the coming months, as Carlsberg UK continues to support and invest in this vital part of its industry-leading beer portfolio."
Paul Davies, Carlsberg UK head of brands, added of the new 4.3 per cent ABV beer: "Tetley's is a jewel in the Carlsberg crown, and we are very excited by the launch of this seasonal ale."
Samples of Northern Cracker will be available at the latest of Carlsberg's Christmas trade shows, to be held at the Leeds Armouries on October 22.
