I like having an excuse to dig a big hole in my yard every couple of
years, so now that I have started making wine and running into
competition for space in our small house, I need a cellar to store
bottles and carboys and such.

In thinking how best to retain the georgia red clay walls, which don't
need much, I considered a honeycomb of 4"Diam x 12"L pvc pipes. Could I
store my bottled wine in the cells? Would humidity in these cells be
problematic? Does anyone know a source for terra cotta drainage pipe to
use instead?

Thanks for your opinions.
