As someone who enjoys wine, but is not an expert, and thinks there's a lot of B.S. involved, I remember one Saturday I was making crepes for breakfast, and I needed to sauté some mushrooms, so I opened up an $8 bottle of Ménage à Trois. Sunday evening we had 2 other couples over for dinner, and I didn't want to serve them the rest of the MaT, so we opened a nice bottle of "90+ point" California Pinot Noir. Then I figured we should do a blind taste test. I recused myself. 4 of the 5 other people preferred the $8 bottle that I'd opened a day and a half before.

The one guy in the group who is a real wine expert was having none of it. He knew which wine was "good" and which "wasn't", and why. Anecdotal, but I think it's a good illustration that there's a lot of B.S, but it's not all B.S.

FWIW, I had a master sommelier on my Sales for Nerds podcast (June Rodil, who is not a stuffy wine snob at all, and is so much fun to drink with). (https://www.salesfornerds.io/episode-5-june-rodil-on-wine-cu...)
