I’m starting this a couple of days early as I know I won’t be drinking anything that will knock any of these off the list.
2012 it’s safe to say was a wonderful year of wine consumption for many of us. I know I've read many of your tasting notes and offline reports from the next day (AML comes to mind most here!) that were quite amazing and the offlines I've attending have been wonderful and memorable. My list could be dozens of wines long without much of a drop off in quality. I’ll keep it short though. One thing I will note though is that of the 12 wines listed fully 10 of them were enjoyed with other forumites.
2012 WOTY: 1983 Chateau D’Yquem
The clear winner for me. This was a wonderful, beautiful bottle of wine. It’s hard to ask more of Sauternes. Depth, spice, acidity, balance. I've had this wine on three separate occasions and twice it has been my WOTY. It isn't perfection but it’s pretty bloody close.
