Nine different vintages of Adam, three to go, Chocolate Rain waiting in the wings, but now got palate fatigue?!
Wait until some later date to drink them? If you can't do that, maybe wait like 15-20 minutes. Also, you could try brushing your teeth now and waiting to continue your tasting when the mint flavors dissipate from your mouth.
C'mon, man. You've been on BA since '08, and are into this hobby deep enough to be drinking 9 vintages of Adam + CR, and you don't know how to prevent/relieve palate fatigue???
