This beer has now been ten years in the bottle, and it definitely seems like that was too long. This is like the skeletal remains of a great beer - it's there in outline but all of the character has smoothed out to the point where it's just a vaguely empty chalkiness and a pure alcohol flavor. Real uncanny valley stuff.
An illusion of rich chocolate on the nose. Incredibly complex but smooth flavor. It was almost a little understated - maybe this was five years' aging talking - but still, this was undeniably delicious.
