Hi, on Sunday afternoon I set a honey raspberry ale fermenting, and by nightfall it was blowing the water out of the airlock, and for the next 24 hours or so it was simply foaming through the airlock. There were even bubbles forcing there way around the gromit.
Just before I had sealed the fermenter I tasted the brew, and it was fruity and very sweet and tasted great. By Tuesday morning it was foaming less and I was able to keep water in the airlock, though it was 'filthy' with ale, froth, and whatever.
Today I've just racked it into a clean secondary fermenter, and I had a taste of it but it tastes very sour.
Now I immediately thought that it was infected but I've been told that it could be the citric acid in raspberries (I used 1.25kg).
Now if this is the case, it'll probably be too sour to drink, is there anything that I can do to neutralize the sourness?
