Yeah, I could rig up something...I just want something consistent, where I can set a thermostat and it stay there. The house is usually 70-72F, so fermentation could be upper 70's or more at times. I really want to make a nice, smooth, sweet stout that never overcarbscand doesn't taste sour, astringent, or metallic. I've tried to lower my primer more and more, left the fermentation longer to ensure complete attenuation, and cleaned, sanitized the crap out of everything from start to finish. So, now I'm down to yeast selection and fermentation temps. Sometimes I have trouble with mash temp and consistently maintaining it, but I've gotten better at it.
