Wine Cooler Features
Is there a lock for the cabinet?
It is important to know that not all wine coolers come with a locking device. Make sure to look for this if your collection needs protected.
What kind of door does it have? UV protected? Double Paned?
I have yet to come across a cooler that does not have some sort of UV protection (usually tinted glass) to protect against harmful light and rays. Light and heat can alter the composition of your wine and ruin its taste.
Most wine coolers also have tempered glass which is less susceptible to breaking since it is stronger that the standard type of glass.
Some models feature double paned or Thermopane glass. This type of glass is the most energy efficient. This type of door has 2 panes of glass that are sealed with air or gas between them. The result is a stronger door and less potential for condensation or frost in the inside pane.
The type of door can also contribute to the coolers aesthetics. Some doors have smoked glass, some are mirrored, etc.
Is the door reversible?
Don’t think that wine coolers like most refrigerators all come with reversible doors. They don’t. If you know exactly where you want your cooler and you need it to open a certain way, make sure you check this.
Or you may want to move your cooler periodically and want this feature. Just know that is is not standard. In fact, more often the door is not reversible.
What kind of shelves does the cooler have?
Chrome, stainless steel, wood, wood with stainless steel trim, stainless steel with wood trim – these are 
common materials for wine cooler shelves. This is pretty much aesthetic and personal taste, but there are some other things to consider with the shelving.
Are the shelves removable? Adjustable? This might be important to accommodate larger wine bottles.
Most coolers are designed to fit standard Bordeaux size bottles. Shelves may need to be adjusted or removed to fit larger bottles. If the bottle size of your collection is varied, you will want to consider this.
How do the shelves pull out? Do they have easy pull out wheels? These are some practical things you might want to consider.
Do you want a cooler that has a carbon filter?
Carbon filters do not come standard in all wine coolers and are only found is select coolers. What a carbon filter does is protect your collection from harmful odors that could potentially ruin your wine. Odors that get into wine coolers can penetrate the cork and affect the taste and the smell of the wine.
If you plan on placing your cooler is a highly odorous environment, you may want to
consider getting a cooler with a filter.

What is the Warranty?
Most coolers come with a standard 1 Year Limited Warranty. Some coolers that have compressors may have a 5 Year Warranty on parts for the compressor. Make sure the warranty offered fits your needs.
