After 3 weeks at 19C/66F my E.S.B. (LME + steeping grains) went from 1.050 to only 1.020 gravity, with a target of 1.012.
The samples was taken from a tap near the bottom of the bucket; it tasted lovely then but was still on the sweet side. I upped the temperature to 21C and left it another week, but the gravity has only gone down to 1.018, so I decided to pop the lid open and make sure it was okay, and found this;
After half an hour I went back to take a second picture, and it looked like this:
Is this saccharomyces having a laugh or I is my beer infected with Brett?
I've looked at hundreds of pictures of infected batches and normal batches and I can't draw the line finely enough to know what this is. I hope you all can help me.
I have upped the temperature once more, as I have no carboy to rack into from under it (and I'm not fond of the idea of carrying one on the bus from my LHBS at the nearest city!) and if it is just my pitched yeast playing tricks then I better get it going again. But if advised otherwise here, I might go out and get some glass, rack into it with some heavy dry hopping and maybe a bit of bourbon to crack down on the nasties.
Alternatively, I could bottle immediately into some 2L cola bottles (not risking glass bottle bombs).
