I’ve recently brewed a pale summer ale with MO pale malt and cascade hops that I’ve made before which was very tasty. Hence why I made it again.
However on this occasion something’s gone wrong with it. I noticed that after pitching (SA04) that the fermentation took a couple of days to get going, and that the whole process was a very slow ferment. O.g. 1050 and it finished at 1012 about three weeks later, should have been 7-10 days going on previous expererience. When I took the lid off the FV to take the final reading and keg it, I noticed a very peculiar clinical kind of smell to it. Also, instead of having a firm cake of yeast and protein in the bottom, it was all suspended in clumps throughout the brew. Some of it was sitting in a thick layer on the top, and some was where it should be, in the bottom although that too was clumpy.
It tastes of the smell and I think that I really ought to chuck it. It’s obviously some kind of infection, but I’m quite fastidious about cleanliness and I’ve never had one go off in the ten years I’ve been brewing, so I’ve no idea what it is. Any ideas?
