Plastic DJs keep getting hard

Postby MrBoy » Fri Jan 20, 2017 14:13

I racked 15L of cider to 3 5L plastic water bottles a week or so back; it had been in the FV about 3 weeks and the gravity had stabilised.

It was bottled cold (5C) and very clear, no sediment in the 'DJs'. I put the bottle caps back on as I have no suitable bungs and left two in the garage. I brought one into the warmth of the house to check fermentation had completed, and have been checking frequently.

I've noticed it has been repeatedly getting hard every few days, so I twist the cap just enough to let the pressure out each time. This is making me worried it may still be fermenting but there remains absolutely zero sediment which I'd view as indicative of ongoing fermentation.

Is it possible this is just the dissolved CO2 slowly coming out of the cider, left over from fermentation? Or do I need to be worried?

Possibly Co2 but you're right to be concerned. if you're not carbonating then adding K-sorbate should stop it. Otherwise, hydrometer is the way to know I guess. what's your OG/fg and yeast?

Keeping it at 5c should remove any chance of fermentation BTW.

Yeah keeping it cool would stall fermentation but that only delays things... When I bottle it could lead to over priming.

I'll compare gravity between the one in the house and the one in the cold garage. Though it hasn't hardened up the last couple of days so maybe it's a false alarm

i suspect its the Co2 coming out of suspension as the brews warmed up.

if no sediment is present then you can attempt to degas it with a few seal shake and undo repetitions safely.

It is quite possible that a malolactic fermentation is taking place, which sometimes happens some time after bottling perfectly clear and yeast stable wine or cider.

It seems to have settled down after a couple or three pressure releases which suggests it was just a temperature issue. I'll keep an eye on it...

Sorry but I can't see the title of this thread without thinking of lecherous radio presenters who've had cosmetic surgery. :P
