I want to take advantage of this nice cold weather and set up a cheap way to lager in my garage. Here is my idea please tell me it will work or am I crazy.
Make a box with 2" foam large enough for my 6.5 gal carboy with a hole on top for my air lock. Use one of the fermentation heaters wrapped around my carboy with a digital controller and put vodka in the air lock.
What do you think?
