So, knowing I'm getting at least 3 brews in for Xmas starting next week and knowing I just won't have the space yet for 120+ odd bottles I'm thinking of putting the stout brew into one of those plastic pressure barrels as looking at upgrading my equipment somewhat from bottles. But I've always read mixed reviews about them, mainly in leaking taps and leaking pressure etc. So, is this a major issue of concern or more to pay attention to the process?. I don't want full bottle carbonation, but do like a little fizz. So would I still need the little co2 cylinders to screw into the top or to top the pressure up as the brew gets drunk?. Also, how long does a brew in these pressure barrels typically last?, are we talking weeks than months?. And any other things with plastic pressure barrels I need to consider?, such as is it worth paying the extra for the king keg ones over the generic budget brands seeing as they assumingly do exactly the same job?, thanks.
