It now (choose one): a) keeps alive an ancient tradition in the face of multinational fizzy lager, or b) does more harm to the cause of craft beer than good.I haven't any opinion, though the always-convincing Martyn Cornell offers a strong case today. What I do know is that the arguments about cask ale seem to mark British drinking culture almost as much as cask ale does, and every time I see a flare up like this, it amuses and heartens me. I'm too distant to have a dog in the fight; I just like knowing people are still fighting about good beer. I'll worry when the debates stop.
