No, i don't think we have got that product, but i could probably find something similar. I prefer the limewashed walls though, all sorts of nasty things can happen if you seal the moisture in the wall instead of letting it through. When i get the roof sorted out, I'll whitewash the whole thing a couple of times again, that ought to minimize the remaining contaminants and sort of "reset" the cave.
Mike: Nope, Danish "Gammelost" (it litterally means "Old Cheese") is just Danbo style cheese that is aged for a very long time. It is an acquired taste though
