I was lucky enough to get mine for free. I saved up some bank rewards points, redeemed them for Amazon gift cards...and bam I was on my way to my first wine fridge. Originally, I thought I would really like one of those dual, temperature controlled fridges, but a) I didn't have room for that in my minimal counter space and minimal cabinet space....kitchen.... and b) you want to SERVE white wines at a lower temperature, but they can actually be stored at roughly the same temperature. 55 degrees is a perfect happy medium in the world of wine fridge temperatures.
My wine fridge....
Now of course, someday, I would love to turn a closet into my own personal wine cellar. or maybe get a trap door in the floor like the below photo...but for now, my 18 bottle cooler will have to do. A girl can dream..... http://www.houzz.com/ has a TON of really cool ideas....
When you SERVE your wine....many think room temperature works for reds, but its actually way too warm. Below is a helpful chart for how to serve your wines.
