I have to agree, strongly, with Tom Wark’s take on biodynamic winegrowing from his blog, although I won’t go quite as far as he did in calling it “a hoax.” A hoax is a fraud or, at best, a practical joke–in either instance, it’s something committed by someone on a consciously false basis. I don’t think the practitioners of biodynamism are consciously doing anything phony. I’m convinced they’re convinced of the truthiness of their commitment. In other words, they’re sincere.
