While wine coolers can easily keep the golden temperature and humidity required for aging wine, this is not what wine coolers are designed for. Frequent vibrations (such as the opening and closing of the door) can be a very bad thing for the process. Wine appreciates darkness, and nobody wants to buy a beautiful wine cooler to keep out of sight. These appliances are generally meant to house wines that aren’t lined up to be aged. For aging wine into the long-term (most agree on 5 years or more), build a wine cellar. Unless, of course, shuttering your windows and vacating the property for half a decade is an option. That’d technically work too. Don’t forget to keep that energy bill on autopay!
