Having a nightmare!
AG No.3 was a slightly optimistic Barclay Perkins 1848 Imperial Brown Stout, way back in September.
All went OK, although efficiency wasn't great and I ended up with 18L at an OG of 1.093.
Fermentation want well, and it was legged into a corny in mid November.
I have periodically been having a taster (be rude not to) and was really pleased - it was all I had hoped it would be. It even compared with the Courage RIS that are on at Tesco's - chuffed!
Last week wondered if it might be a little 'bland', but put it down to the cold temps - certainly no off flavours.
Tried some again last night - really, mouth puckeringly, sour. Long horrible aftertaste. Thought I would have a taste at lunch today, when I hadn't had a few beers - same. Worse if anything.
Its obviously an infection. When I bought the corny (over t'interweb) it hadn't been cleaned by from the last brew, and smelt awful, so I gave it a thorough clean. However, if the infection had been in the corny to begin with logic suggests it would have presented earlier, not two months down the line. I presume it is infection I have introduced when popping the tap on to have a taste - I always thought that, as it is under positive pressure, cleanliness isn't such an issue, but I am clearly wrong, and now worrying about my other 'grand beer' ageing in another (new, shop bought chinese) corny.
I know what I have to do - bin the beer, cry a little bit, really clean the corny and change practice. Just so gutted at loosing a great beer.
Mainly I'm just having a moan, although all suggestions are appreciated.
