Do folks think it's bad to have temps swing say from 50-70 here and there over weeks during fermentation in carboys? I am working with mead and cider only... I just don't have a super stable fermenting room...
That's what I use. Do you wrap them around the sides or just sit them on top. I use one regular rectangular mat around my carboys and that works just fine with a towel to block the light in my unheated basement in the winter. Also, the pads are temperature controlled. I could throw a blanket on top if needed but the basement stays mid 50s or higher and I don't remember needing one previously.ok thanks.. yeah i try to have them all on heat pads which seem to be the right temp - seedlings germination mats- a very stable 65-70 for the materials it seems..a little less if the room gets colder..
Good call - thanks much...!Many times on carboys I'd just tape a thick piece of insulating foam over a temperature probe to keep the probe firmly against the carboy. The wider the area covered by the foam, the better for getting a truer reading of the temp inside. A thermowell or if you wish to spend the bigger bucks on a Tilt or Rapt Pill hydrometer will also give you accurate internal temps.
Once you know what the internal is doing then you can better guess if the large swings in ambient temperature are an issue for your ferment.
