I'm just in the process of making a heater/cooler for my wine fermentation. I'm using peltier chips, which for anyone who doesn't know get hot on one side and cold on the other when you pass a current through them.

It's basically going to be four peltier chips sandwiched between two (2.5mm thick) stainless steel plates. My design will have dimensions to hold 6 demijohns (600mm x 400mm) but this could be adapted to suit a fermentation bin. I'm using 4mm ply wood in between the two steel sheets with cut outs for the peltier chips to sit in, a 9mm thick sandwich in total. It will be mounted on a stand (easy to make from MDF) and controlled by a cheap (£2.50) 12v thermostatically controlled relay and powered by a (£5) 10amp 120w switching power supply. By reversing the polarity to the chips you can choose which side gets hot/cold hence using it as a heater or cooler. All you need then is to make a box to go around the fermentation vessel(s) and sits on top of the stand. Think of it like a posh heating mat.

I'll post something when it's built as it's a little hard to describe without any pictures and it's much simpler than it sounds.
Here's one in action.

I've been experimenting with making wine under pressure. At high pressure. (20-30psi) I can finish a wine in a week with no bad tastes resulting from stressing the yeast. Same with some beer yeasts. Like with beer, the pressure keeps it all clean. Also much rounder taste. I have a thread on here somewhere about it. (fermenting wine under pressure.) I got the idea from Dr. Hans on YouTube. He's done a lot of beers, also lagers at high temps. They finish fast, they finish clean.

Fermzilla /fermentasaurus is the bomb.

My Canadian Blonde temp.is up and down. I Got the temp to 21....crept up to 24 this evening, I suppose it'll lose a degree overnight, might try the wet towels.
