I was doing a job in a commercial wine cellar. Climate controlled building with storage units for rent so folks can keep their fancy bottles of wine stored properly.
I imagine at $16,000 this cellar is probably geared for that market, rather than Ma and Pa Johnson to keep their vegetables in. And environmentally friendly for the uber-liberal-rich.
One of the reason the uber liberal rich have wine cellars is to show them off... it's more a status thing than just a place to keep wine. This thing is waaaay too utilitarian to pass the phony snob test...
