Saw a 20L one at previous job but it was brand new so left it alone.
I have 3 x 5L demi johns but its a pain in the proverbial to get the liquid out. I borrowed it from the lab but never did get around to returning it. If they could see my shed now they would know where the lab glassware supply ended up instead of blaming the uni people next door!........
Anyway, this beast is for Kev to do trials of GF beers when he gets back into the brewing, i am just testing it to see whether it can be used and its working a treat. So before he asks for it i am hammering out batches of cider. On my 3rd batch with the same yeast which was 2nd generation when i started.. One more batch fills up the keg so will prob stop then and check out how the yeast is holding up before doing anything else with it.
