Depending upon the size of the wine cooler, it may have one or two temperature zones. Two temperature zones make it convenient to store more than one type of wine. Experts say that white wines should be stored at 48 to 55 degrees Fahrenheit, depending upon the type. Red wines, on the other hand, should be stored at between 60 and 68 degrees, again, depending upon the type. Usually, the number of available temperature zones will depend upon the size of the wine refrigerator. Smaller, countertop units usually have only one zone, larger units will have two or more.
There are two types of cooling technology found in wine refrigerators: Compressor-based and thermoelectric. Wine coolers with compressors work like traditional refrigerators, using coolant and fans to cool the air inside the wine cooler. Hot air is vented out the front, away from the cooler. Thermoelectric wine coolers do not cool air, rather, they rely on heat transfer to remove the heat from inside the compartment, and the heat is usually vented out the back. That means that thermoelectric coolers require a fairly generous amount of space around them to allow the air to circulate. While wine coolers with thermoelectric cooling systems can be used as built-ins if the installation is planned carefully and plenty of room is left for circulation, most experts advise against it and say if you're going to have a built-in unit, go with a compressor-type wine refrigerator.
Keep your beverages at the perfect temperature with a wine refrigerator. Find wine coolers with single- or dual-zone designs and a variety of features to keep your whites and reds at the ideal serving temperatures.
