I just bought a Brew Belt because I'm starting to get into winemaking and with my first bath nearing fermentation, I wanted to make sure I didn't have any issues with fermentation. Right now, my primary is a constant 64 degrees (it's been cold in Ohio) but before I pitch the yeast I want to make sure the temp stays in the 70s. Since I work during the days, has anyone had experience with leaving the brew belt on all day unattended? If this seems to be and issue, I can turn it on all night while I am home and then before I leave for work just insulate with a blanket. Thoughts?
