I am moving on to my 2nd brew this coming weekend and plan on doing a Kolsch style brew. I already have an amber ale and think a nice Kolsch style would be a great compliment to the Amber. My question though is during the secondary fermentation the recipe calls for the brew to be kept at a 50 degree temp. I plan on using my Kegerator as the secondary fermentation however when checking the temps it sits between 46-48 degrees. Having the temp lower than called for will it affect the yeast and fermentation or will it be fine?
