Stonch has a blog post on how to make sure cask ale is served in optimal condition. Read the comments thread as well.
For us Norwegians this discussion is almost like observing a parallel universe. But things are changing, slowly, here, too. Nøgne ø and Haandbryggeriet are offering cask ale to pubs now, let’s hope their customers know how to treat it properly.
Even having keg versions of some of the Nøgne ø beers is quite a change, both their Porter and the Imperial Brown Ale are great on tap.
