This question has probably been addressed before and apologies if this is a repeat, but I couldn't find it through the search. Anyway, I have two caps for my pressure barrel. One has a valve for the CO2 bulbs and the other looks like a little plastic plug. By doing some reading around, am I right in saying that they both have a pressure release system. Presumably they allow sufficient pressure to carbonate beer, but not too much for the barrel to explode? With that in mind, can one do the primary fermentation in the pressure barrel and then leave it to condition in the barrel without having to transfer the beer anywhere? If the pressure got too much it'd just release some gas. Also, if they both have a pressure release system, what is the point in the non-gas cylinder valve type of cap?
