Hi, l'm brewing my first batch (5 gallons of IPA). I'm fermenting in my cold garage and I'm controlling temp by immersing my carboy to half way in a warm water bath heated by an aquarium heater on a timer switch. I've got a stick on thermometer on the carboy and temp fluctuates between 66 and 70F. My questions are this: Has any one else used a similar method of temp control and if so has there been any adverse impact on beer due to the bottom half of the carboy being warmer than the top? Also, is the fluctuation between 66 and 70F likely to impart any unplanned results on the beer? Thanks.
