Cool, without a doubt, but I am not sure how effective it would be. It seams a bit cramped. The idea of a wineceller, at least to me, has always been a place where you could spend time, perhaps even with chairs and a table or something. This is more lile storage. Fancy storrage, for sure, but still storrage. It may be a good selution for the "city-boys" with limmited space. Kind of like those garages, that are hidden underground.
