Sour beer.

Lep · Feb 27, 2010

I have opened two bottles of a coopers LME dark ale kit and they are sour. Is this a flavour that is likely to lessen over time? or get worse? The flavour is......unpleasant and is especially apparent in the aftertaste.

I never really noticed anything growing during fermentation, no film etc.

How long have they been in the bottle? It sounds like an infection to me (you really need to be zealous with your bottling sanitation).

Either way, give it time, and see if it improves.

Good luck!

Generally, no. If it's infected, it's infected. Did you get a gusher when you opened it?

Lep · Feb 27, 2010

No gusher. it pours nicely.

and I did clean with hot water and sanitise with sodium metabisulfite, but I guess something went wrong...

edit: they've been bottled for two weeks.

Sodium metabisulfite is not an ideal sanitizer, I would recommend Iodophor or StarSan.

Lep · Feb 27, 2010

I'm going to have to look into it...yeah.

Hah. I may have soured my batch afterwards, and I also dropped a carboy with about a gallon of said batch in it. Calamity brew day.
