The tools for making your own wine cellar can be as close to the garage, storage or basement as an excellent base for making a wine fridge is a mini fridge. Mini refrigerators can be found cheaply as they are the fridge of choice in student dormitories everywhere. But they are also good small refrigerators, so this is the choice in student homes everywhere and a slight adjustment of the thermostat or conversion with an external timer produces a wine refrigerator that is only as good as a $ 200 to $ 400 " professional version ".

Adjusting the thermostat regulator
Pull the thermostat switch button on the mini fridge. The calibration screw is a small screw next to the button.
Rotate the calibration screw counterclockwise with a screwdriver. Your goal is to determine in what direction the compressor is off and on. After 24 hours, take the refrigerator internal temperature.
Make several small adjustments to the calibration screw until the internal temperature reaches 55 degrees Fahrenheit. This is the optimum temperature for storing wine.
Adjust the temperature with an external timer
Buy an external timer and a thermometer. The timers can be found in the hardware stores of the device. Refrigerator thermometers are available at grocery stores.
Install the timer. Connect the mini fridge power cord to the timer. Then plug the timer into an electrical outlet.
Adjust the current setting in the refrigerator to the lowest setting and place the thermometer in the mini refrigerator. Let the refrigerator run and take the temperature. When you reach 55 degrees Fahrenheit, the wine storage temperature is right.
Increase humidity for wine storage
Adjust the storage humidity. Refrigerators have a low humidity due to the design. Wine chillers are designed to retain humidity at 70%. Use a hygrometer to measure the moisture content. You can find a hygrometer in a dollar store.
Place an open liquid container in the mini fridge to increase humidity. Use a cheap wine as an alternative to water, as the viscosity of the wine is different from water.
Measure the temperature of the wine or water. This is more accurate than measuring the air temperature, since your goal is to keep the wine liquid at 55 degrees.
