Building a closet wine cellar can be a very simple project or quite an investment of time and money. I chose the "simple project" route and turned my office walk-in closet into a make shift wine cellar. I do want to further my project and put in a cooling system, insulation, wood flooring (instead if carpet), and some nice wine shelving or racks.
Some things one might consider when building a closet wine cellar are:
1. Keeping the temperature and humidity at the right levels
2. If you install a cooling system, you need a nice tight cellar door
3. Make sure the closet is properly insulated
4. Location of the closet should be in a cool spot of the house
As you can see here I have just started this project and have lots of wooden wine box lids that I plan to put on the walls for a more cellar like look! I place a bunch of old wine bottles on the upper shelf for decor. I plan on putting in wooden or tile flooring and insulating the walls too. The cooling system I will invest in as soon as everything else is finished.
