Bottled Doom Bar, like most bottled beers, is filtered, pasteurised, artificially carbonated and absolutely nothing like the cask beer. I always have a few bottles of the more flavoursome continental lagers in the fridge, though I doubt that I drink more than half a dozen bottles a year. Very nice on a hot summer's afternoon. Apart from that, I avoid all bottled beer apart from bottle-conditioned ones, the ones with a bit of yeast in the bottom and which are unpasteurised and naturally carbonated. Until about 20 years ago, bottled Guinness was bottle-conditioned and was miles nicer than the draught. Lamentably, 'tis no more. My very favourite bottled beer is Duvel, though at eight percent plus you don't want to be necking too many. I pour most of the chilled bottle into the glass in one go then glug the yeasty bit at the bottom of the bottle. Gorgeous!
