Most likely, yes. I use two Visanni 52 bottle wine fridges for fermentation chambers. I use an STC-1000 temp controller to keep the temp where I want it. On the Visanni, you can adjust the screw in the thermostat and get down close to freezing temperatures if desired. What model is your Wine cooler? Not many will fit buckets, especially the larger ones for making wine....mine barely fit. Sounds like you scored with this one.
