Actually, there have been pretty big changes in how young Barolo and Bordeaux are in the last decade plus. They generally seem much less closed, less fiercely tannic, much more enjoyable. And that isn’t just the “modernist” producers in those regions, either.
I think a lot of us are watching with curiosity to see how much better, worse, differently, sooner, later etc. they develop over time.
Just a couple threads that come to mind, but there is much more of this discussion around the board.
