It’s the nectar of the gods.
Please note that the cited author is not a viticultural expert. She is a professor of “sustainability,” whatever that is. She is also from Sweden, not exactly a major producer of wine. The article does not cite any statistics showing the replacement of Pinot Noir vines with other varietals. It contains only speculation that varietals that prefer cooler climes (Chardonnay anyone?) may be replaced with other varietals. Basically, the article is just more climate change BS. It is certainly possible that Pinot Noir is being displaced outside of Burgundy, because by and large Pinot Noir based wines produced elsewhere are pale imitations of those produced on the Golden Slope.
