I made a Brewer's Best kit of oatmeal stout Jan 31 and pitched around 73F, assuming it would cool several degrees in the following 24 hours. It began to ferment within 6 hours and the next day, around pitch+18 hours, it was very active - 2-3 bubbles per second - due to unusually high temps in the house. At that point I moved it to a much cooler spot, tried wrapping the fermenter in wet towel to cool it to no avail. Finally the temperature dropped and fermentation slowed significantly at about pitch+25 hours. As of Feb 2 there has been basically no activity that I can see. Gravity is at 1.028, from an OG of 1.072 and it tastes sweet (esters?) and a bit like grain. Should I re-pitch to reduce the gravity and hopefully finish the fermentation, or is it done? If the former, how much yeast should I add?
Thanks in advance!
btw, it still tastes pretty good.
