cask conditioned demijohn

Post by jaroporter » Tue Mar 01, 2016 6:04 pm

i have had part of a batch of bitter in a demijohn for, damn, now i think about it going on six months. forgot protafloc, damned thing never cleared, keg was a let down, racked the excess into a DJ - under airlock - until i could bring myself to do something about it (it's got a lot clearer, but still has a slight haze!). finally just decided to just chuck it but decided to pour a pint as you do.. and total revelation!

it was clear it had undergone some secondary fermentation/conditioning in the DJ as i'd seen positive pressure in the airlock and evidence of slight yeasty deposits around the neck, but it's held that condition amazingly. i'd have thought the airlock would have led to it eventually going flat, but even with no positive pressure in the airlock for months, it's as lively as a freshly drawn cask - that perfect gravity poured pint! properly smooth and light (i often find bottled beers, even unprimed, develop harsh large bubbles, presumably as they're drunk unvented)

it's still a pretty sub-standard beer, but the serving condition makes it fantastic to drink. i'm gonna have to experiment with this more as while i love the handpump/keg setup i have recently been longing for that gravity poured effect (kent and unrepentant! ;) ). five litres is also a reasonable amount to crack with a couple of friends.

seems like the airlock has been venting it, but retaining just the right condition. it was filled right up to just under the bung so very little headspace also. i wonder if the use of a quality silicone bung has helped. some things to think about for this southerner at least.. :beer:

Did I get this right, you were thinking about chucking a beer just because it's not bright and has a haze?

ha not quite i probably wasn't so clear. the main issue is that it never really tasted right - not definite off that would have led to immediate disposal, but just like it hadn't fermented well/cleanly. but i had thought that it would have cleared by now even if it just took some time.

anyways, day two in and the flavour/feel has rounded/evolved and lost the initial liveliness but still good condition. essentially it drinks like a day two cask ale..

the beer itself is still a bit crap, but i've got a tasty pale ale ready to sacrifice to round two..
