First of all, why do you need a wine cooler at all? It is a device only needed by those who love their wines and actually cherish a glass of chilled goodness while turning over the pages of a crime thriller. Well, the crime thriller is optional, but as you can read at the Cooling Wine website you absolutely need to get yourself a wine cooler if you love your wines.
The next question is what is a freestanding wine cooler? The answer could not be simpler. It is a cooler that stands in a corner of your house on its own with its belly full of expensive wines that you have been collecting. The other variant is built-in wine coolers that are installed inside the kitchen counter if you do not have enough legroom in your house.
The direct benefit of freestanding wine coolers is the amount of bottles you can store. Technically you can easily buy a cooler that holds 60+ wine bottles but the capacity of built-in coolers is obviously limited by the size of the kitchen counter.
The second benefit is of course flexibility. You can keep the freestanding cooler anywhere in the house. On the other hand, if you are in the mood for a glass of wine before you sleep, you have to get the wine from the kitchen and put it back once you are done which can easily ruin the mood.
So if you are a true wine connoisseur and love your chilled wine, it is always better to go for a freestanding wine cooler.
