He lives about 20 or so miles from me and our wine rooms seem to stay about the same temperature, so I think if you go a few posts past that one you will see that his ambient temps were in the low 60's, so that's a heating pad, as his temp during ferment was in the low 70's.
Yep. That's a heating pad. In the future, I think I'd use it in the height of winter went the room gets down to 58*.
Planning to start two to four wines this winter (depending on whether my buddies are interested in going in on a kit or two). So, it may see some use.
