I went to UGC in SF as well (actually tasted with Vince for some of it), and I’ll add my thoughts.
As context, take what I say with a shaker full of salt. Bordeaux is not really my thing (I began my wine journey with Loire Cab Franc), and I went more out of curiosity and wanting to learn more about an important wine region rather than a zealous enthusiasm for the wines.
I basically agree with a lot of what Vince, Sam, Juergen, Panos and others have said about Leoville Barton being the standout wine in the room. Lots of complexity and depth on the palate, yet restrained with good structure. I really liked this.
Gruaud Larose was probably second for me among the St Julians, although I liked it less than the Barton – it lacked the pop and intensity of the Barton, but I liked is restraint and “classicism.” Langoa Barton was also enjoyable, but a simpler wine.
Leoville Poyferre was velvety and fruitier than the Bartons or the Gruaud, but I didn’t find it too offensive or over-the-top; (I actually think the vintage’s restrained nature helped this wine’s balance, based on the reputation of the estate). Similarly, the Beychevelle also felt surprisingly lush and rich for a '21, – I liked it ok, but it seemed a little simple and one note (like the Poyferre). I had Lagrange, but, for the life of me, I can’t remember anything about it (which is probably saying something).
Moving on to the right bank, I really liked Canon. It felt like a quieter version of the '20 I had last month: it retained the elegance and delicacy on the palate, and had a similarly spicy finish, but lacked the '20s intensity and length. Still really good. Canon-le-Gaffeliere and Grand Mayne were fine, but not particularly memorable.
Clinet really stood out to me among the Pomerols – delicate, relatively weightless on the palate, and while perhaps a bit sleek, it still felt classical. I liked this a lot. Le Gay and Pavie Macquin both seemed rather amped up and velvety in comparison – good wines, but not my cuppa.
Among the Graves (sorry, Pessac-Leognans), I liked the Carmes Haut Brion quite a bit. Graceful, charming, delicate, and elegant. This producer deserves its hype. I disagree with Vince on Haut Bailly – I thought this was very enjoyable and balanced, with hints of earthiness and pleasing green notes to balance the fruit. Yum.
Tbh, I don’t quite understand the enthusiasm for Rauzan Segla or DDC. I found them both to be rather lush, velvety, fruity wines with not a lot of interesting mineral or really any non-fruit flavors. They aren’t bad, but I would lump them together with Poyferre, Beychevelle, and Canon-le-Gaffeliere as kind of on the correct, acceptable, un-spoofed, but boring side of the modern, Bordeaux spectrum.
Unfortunately, I didn’t get to most of Margaux, Pauillac, or St. Estephe. I was chit-chatting too much. The Cantenac-Brown was fine and I remember liking Cantemerle.
I thought the '21s were, as a rule, fine, but probably nothing to get super-excited about. If they were 30% cheaper, I would consider getting Canon, Carmes, Haut Bailly, and Clinet. I might actually pick up some Leoville-Barton and Cantemerle. Though I’m probably most excited about '21 Baudry.
