Castlemaine XXXX has become the first casualty of independent brewer Daniel Thwaites' new Kaltenberg contract and will be axed by the Blackburn brewer when the brand switches from Carlsberg-Tetley to the Interbrew stable in a few months' time. But speculation that Carling and Carlsberg could also disappear from the Thwaites portfolio was dismissed by sales director Brian Jenkins, who confirmed both brands will stay. He added, however: "Both these lagers will remain on our list but because the Kaltenberg brand is now under our control we naturally want to see it succeed in the marketplace. "The deal to brew Kaltenberg at our Blackburn brewery is a major one and just over three weeks into the contract it's fair to say we have been inundated with requests to take on the brand." Jenkins said that Thwaites set out some years ago to strengthen its position in the beer market. "We wanted to be in a position where we either brewed, packaged or controlled a brand in each sector of the market. "Our recent deal to become sole UK suppliers of premium German lager Warsteiner and the contract to brew 3.8% abv Kaltenberg has helped us to achieve that. "We want to protect brewing in Blackburn by growing our lager business and we could not afford to ignore something which had such a large percentage of the market," Jenkins said.
