Unless the 16 has changed since I had it earlier this year, I wouldn’t even bother opening one, too tight and tannic. It’s a long term wine for sure. 12 should surely be drinking well now, it’s always been a warm, forward vintage. I drank through a bunch of 13s and 14s when they were young, but I haven’t had one in several years to know how they’re drinking. Might be good, might be not showing much. I think 11 was always drinkable.
