Each wine fridge model will have its own set of features and benefits, but here are some things to look for when shopping:

• Single or multi-zone technology: Single-zone wine fridges keep all bottles in the fridge at the same temperature and humidity level. Dual-zone and multi-zone wine fridges have two or more compartments, allowing you to store wine at different temperatures within the same refrigerator.
• Charcoal filter: Many 24-inch wine coolers feature charcoal filters, which eliminate odors from the interior cabinet. Odors can permeate corks, affecting the flavor of your wine.
• Humidity controls: Most units automatically maintain a humidity level between 55% and 65%, but some 24-inch wine refrigerators allow you to adjust the humidity. This can be helpful if you live in a particularly dry or humid region.  
• Automatic defrost: Many wine fridges include an automatic defrost feature, much like standard kitchen refrigerators. When the cooling cycle is finished, the refrigerated parts of the cabinet are defrosted automatically.
• UV light protection: Many 24-inch wine coolers have glass fronts to showcase your wine. These units typically feature UV light protection, filtering out a certain percentage of harmful UV rays, which can cause “light strike,” altering the taste of your wine.
• Door lock: Some 24-inch wide wine fridges feature a simple-to-use door lock, keeping wine out of reach of children at home or would-be thieves in commercial spaces.
• Vibration-dampening features: Some wine fridges feature shock-absorbers and insulating foam to help reduce vibration, which can disturb the sediments in wine.
