i have been brewing for about a year with no problems, i made the mistake of trying to brew an ale in to cold of conditions. It started out fine but quit perking with way to high of a gravity. I have since heated the wort by placing the pale in a tub of warm water that i keep adding warm water to. It is now perking but way to slow. Since it set iddle for days would areating be a good idea. its reache 80% attention gravity has gone from 6.1 to 2.0 i usually finish at .96 with this recipe?
