Hi! I am a newbie; I started with kombucha and am now experimenting with elderberry wine (from concentrate or dried berries; I hope to harvest my own berries next year) as well as mead and graf. Our boiler is in the basement, so the basement is the same temp as the rest of the house. Right now, with the heat off, house and basement are 76 degrees F. My graf took less than the expected time to finish bubbling. We are planning to put our old refrigerator in the basement, cranked up to 55 or 65 degrees. People are suggesting swamp cooler-type methods to cool down my fermentors, although I am too much of a newbie to know if the faster fermentation is making a difference in taste. What I do know is that my favorite bottled wine, Middle Sister Rebel Red, tastes like prune juice, I think due to the summer heat; it was in the eighties a few weeks ago. When I am ready to bottle my wine I hope to have the fridge down there. But I am also wondering if this system might work, or if I would need something fancier with nitrogen to prevent oxidation.
