I think this piece is more of a reaction to the hackneyed articles we've all seen about how wine knowledge is all bs. It's a qualification of those conclusions that does a good job of explaining that the reality is a little more complicated.
I think it is a breath of fresh air to read something thoughtfully put together.
If you just care about the bottom line, yeah there isn't anything shocking. Wine is real.
If you want to learn about some of the details, then this has substance. I certainly wasn't familiar with the studies mentioned and their data. Did you know that 11/13 experts could identify the varietal and country of origin for a French Gamay?
IMHO, the content is vastly better than articles and threads with people squabbling about the latest thing Elon said on twitter.
Is this just a filter bubble thing? Is it "new" to many people even though it isn't to me?
Or do we just like to feel snobby about knowing the truth?
