Hi all,
I'm just trying my latest out of the fermenter, it's hoppy english bitter. About 30IBU, made with golden promise, about 7% medium crystal S-04 and 20g of goldings at 20min, 10min and 20g of fuggles at flameout.
I'm getting this sour puckering mouthfeel off it. I was aiming for something really nice and smooth, and while its tasty, this puckering feeling is just hanging around for ages.
I didn't strain my wort before I chucked it in the fermenter, so it has all sorts of hops and crap in it. I've done this plenty of times and it has never turned out to be an issue like this.
Funnily enough, this has happened before, with a similar style of beer I made quite a while using extract, goldings, and S-04. In fact it's the only other time I've used that yeast.
Any idea what's going on? From some research I've done, it seems that my beer is either infected with an acetobacter, or I've extracted tannins from my grains.
Kind of a bummer really, I had high hopes for this beer. I'm thinking about steeping another 100g or so of crystal and chucking it in the fermenter (still bubbling away at about 3-4/min) to balance out the acidity.
Cheers,
James
