In late October, a conference called Tasting Climate Change was held in Canada. The subject was the impact of climate change on wine growing. An important question asked was: is it justifiable to plant vines where they have to be irrigated? Undoubtedly an interesting question.
We asked ourselves approximately the same question when we wrote the book about biodynamic and organic wines a few years ago: is it justifiable to plant vines where they must be sprayed with environmentally hazardous products?
