I have a Vissani 50 bottle wine cooler for sale that I’ve been using as a fermentation chamber. Fits a 6.5 gallon glass carboy with carboy cap and blowoff tube, corny keg, or a 1/4 bbl sanke (that’s the one in the picture). Works great with an inkbird temp controller and can go down to 39 degrees. If you still want to use it as a wine fridge, I have all of the shelves still.
Pick up in NYC, price is $200.
