While they might look similar, there’s a clear difference between a mini fridge and a wine cooler. A mini fridge is set at a cooler temperature to keep bottles and cans cold and frosty. These are also useful for foods that need to be refrigerated.  A wine cooler, on the other hand, is slightly warmer than a mini fridge. This is to allow the perfect temperature for serving red, white, and sparkling wines. These coolers aren’t suitable for storing foods that need to be chilled.
