Or rack half to fresh keg to (I'm guessing) mix your sours rack rest off trub we gotta remember autolosis man I love spell check...And I'm planning to buy a couple of kegs this week for bulk aging sours. With those I'd transfer half the keg out each year and I definitely want to leave the crap in the bottom for the next batch. Hmmm, may have to take this more seriously.
One thing to be wary Is krausen or hop debris possibly faking onto floating dip tube. But I suppose easily cleaned and swapped with another keg lid.
The cheapest stainless fermentor I can see on Aussie Market is $150 A cornie keg is a third that coast of second hand...
Heck Sorry Craig for the thread derail wopps.
