The beers marketed under the brand name Grimbergen are now brewed by two different companies. Alken-Maes located in Alken in Belgium brewed the beer before 2008. Alken-Maes was taken over by Heineken International in 2008. As part of the takeover the brand name Grimbergen was transferred to Carlsberg Group, but Heineken was given a long-term license to use the brand name in Belgium. As a result Alken-Maes brews the beer for the Belgian market, while Carlsberg is responsible for the marketing outside Belgium of the beers that it brews under the Grimbergen name at its Kronenbourg Brewery located in France. In the Netherlands, Grolsch Brewery is responsible for the marketing of Grimbergen that is brewed by Alken-Maes.
My take is that Grimbergen should be listed as Carlsberg (worldwide), since Heineken only have the rights for Belgium now.
