I have 18 gallons of Chilean Merlot bulk aging in a 54 liter Italian demijohn and 3 gallon better bottle. I would like to do a cold stabilization on that batch and now would be the perfect time in the garage here in Chicago. My garage is semi insulated and i do have a furnace with a low temp thermostat that goes down to 35 degrees. I would like to try to keep temp around 30 or a bit below.

Im concerned about doing it out there in the demijohn due to it being thinner than a carboy. Any thoughts on that? (I do not have any spare 6 gallon carboys to use right now)

Has anyone else done a cold stabilization in a demijohn? Thanks!

Cold stabilization can be done at higher temp say 50 degrees, just takes longer.

Id like to do it quicker at lower temp if possible... from what ive read, it should only take a week or 2 at 30 degrees.

You should be fine. Demijohns are a lot tougher that you would think.
