The autoclaveable HEPA ones are extortionate here. They were pretty costly when I got a load from St ...

I Inject oxygen at 2L per minute inline, via a stainless stone, from the chiller to the FV (Although 38L of wort and 120L of foam is difficult to get into a 60L fermenter :) ) Too many of my beers developed a 'house flavour' with storage that I can only put down to infections picked up during aerati...
