my second beer is in the fermentor right now...a belgain white ale. i'm using the wyeast 3944. according to the yeast package it stated to ferment at 70-75* f. my problem is that i live in an old apartment and during the winter it is hard to keep my ambient temperature above 65* without running up my gas bill(last month cost me $481!!!) so right now the temperature in my closet is 66* f.....is this going to be a problem? if it is, is there anything that i can do to correct this? do i have to give it more time to ferment since the yeast will be working slower? thanks for any help.
