A wine refrigerator is a specialized appliance designed to store wine at optimal temperatures. Unlike regular refrigerators, which can be too cold for wine, these units maintain a consistent temperature range, typically between 45°F and 65°F. This helps preserve the flavor and quality of the wine over time. Many wine refrigerators also feature adjustable shelves and humidity control, allowing for the proper storage of different types of wine, such as red wine and white wine. Some models come with glass doors for easy viewing, while others offer UV protection to shield the wine from harmful light exposure.
