I have just done another SG reading of my latest beer this morning, the gravity has dropped again from 1009/10 to 1008, the yeast head has subsided to a thin covering now but I still can't bottle until I know it has finished.
Trouble is, I drank the run-off of beer just now (I no longer return it to the fermenter to reduce the risk of infection) and it's started to taste off!
I am hoping (really hoping) that what I am tasting is acetaldehyde, a sort of green apple flavour, which is a by-product of fermentation that if I'm right, left for a while, the yeast will clean it up, if I'm wrong I've got 40 pints of vinegar, Ah!
What I don't get is how, every other day I have tasted it, the flavour has been great, just this last taste today that it is noticeable; perhaps now most if not all the sugar has been fermented it no longer masks the taste?
Is it vinegar or beer now?
