It is important to make sure that the glass door beverage refrigerator you purchase is properly insulated. While it may seem like a small detail, it is essential to keep your drinks from getting too cold. Keep in mind that the temperature of the drinks inside the refrigerator is directly proportional to the temperature outside. If you keep the drinks warm, they will stay warmer. If you keep them cool, they will stay cooler. Make sure you get a unit that has plenty of insulation if you want to enjoy the best quality beverages for longer periods of time. Source: topfridge.net
