While researching the refrigerator root cellar I came across an interesting concept known as a spiral root cellar. This design is for folks with very little space who want to have easy access to their chilled products. Most versions seem to be installed in the kitchen floor with a trap door for access. This solution seems to be only available in Europe, and it's not cheap. About 12 thousand dollars, which in the long run would be cheaper than an expensive wine cooler thanks to the fact that it uses the earth for cooling. Of course I'm wondering if some modification can be made to be able to build one yourself, but I think we will be sticking with the refrigerator root cellar design for now.
