How to Make a Cheese Cave Out of a Refrigerator

My Cheese Cave
By Bob Albers*
Cheese caves are wonderful things. Especially when you consider the wonderful things they contain and the wonderful things we get out of them. If you live in the mountains and are fortunate enough to have a real cave on your property, you are ahead of the rest of us.
I live in perfectly flat country. There are only two high lands here: the Mississippi River levies and Monkey Hill in Audubon Park. Both of these are man made and don't have any caves. Monkey hill was a WPA project, so the children of New Orleans would know what a hill looked like. Today, the engineering students at Tulane University measure it each year as part of their curriculum.
I, like many, have to find old refrigerators, dorm sized ones or wine chillers to modify with external controllers. It seems that the warmest temperature available in a refrigerator is about 40F. Wine chillers aren't much warmer. For cheese aging, we need to hold a temperature of around 50 to 55F.
Then, there is the question of humidity. Cheese caves need to be relatively humid. There are many devices on the market to regulate humidity. Some dry the air while others make the air more humid.
When your "cave" is a small refrigerator, the humidifying device needs to be small so as to allow enough room for the cheese. Also, there must be some kind of control to keep from over or under humidifying the cave. This leads to a controller which senses the humidity inside of the cave and turns the humidifier on & off in response to conditions inside the cave. While the sensor probe needs to be inside the cave, the controller doesn't have to be. Let me share with you how I addressed these issues.
First, is the matter of a budget. Perhaps you have a money tree in your back yard, but my thumb isn't that shade of green.
I noted a sale at Kmart on "dorm sized" refrigerators. I was able to purchase an Amana model number AMA27S1 refrigerator which is 2.7 cubic feet in volume and measures 26.1 inches tall. (Just right to go under the counter in my office as you can see by the photo here.)
The next thing required is to control the temperature of the fridge. Looking on Amazon, I found a WILLHI model WH1436A device pictured here for $28.50 (click here).
The humidity controller looks just like the temperature controller but it's model # is WH1436H and it is also obtainable from Amazon for $37.50 (click here).
That's all well and good, but now we need a source of humidity. Sticking with my favorite Brazilian river on line department store, I found a "Bottle Cap" Humidifier pictured below (click here).
It fits in the door rack of the mini fridge. It is powered by a USB circuit so I had to add a USB power cube obtained from, you guessed it, Amazon.com for $6.99 (click here).
Connecting it all together, here you see the two controllers mounted to the shelf above the fridge. The one on the left side is the temperature controller and the one on the right is for humidity.
The black thing plugged into the humidity controller is the USB power cube.
As I have been opening and closing the cave while writing this article, the temperature and humidity are a bit out of whack.
With the door open, you can see the temperature probe (left) and humidity sensor (right) hanging down from the top of the enclosure. When I shut the door, the door seal forms around the wires.
Ok, now let's see what the total cost of my fully automated cheese cave is:
Refrigerator $99.99
Temperature controller $28.50
Humidity controller $37.50
Humidifier $6.40
USB power cube $6.99
Total $179.38
If you happen to have any of these items already, you are ahead of the game. I hope someone finds this helpful. Now, let's make cheese!
