Thats an awesome job on the cold box, inspiring me to try and build one. Whats that black threaded pipe in the back? Propane heater?Probably worth revisiting once per year. This is season #4 on the wine box. It was 103 degrees in the garage and 65 degrees in the box. Still working like a champ. No changes since I first made it, besides adding a handle made from left over metal and a horseshoe.
Is there an available link to the WineMaker Mag article? Not at detailed, but it might be helpful.
