1980's and early-1990's Duckhorn. Why the price slide?

Three Palms was always great Merlot. Had an epic night once at a N Vegas Gentleman’s club that revolved around this wine.

That sounds suspiciously like a “What happens in Vegas stays in Vegas story.”

Well I just had what I would consider something with a little more age on it. This thread got me curious but not ready to jump from 2012s to the 70s, I got a 1991 Duckhorn cab. My first impressions were notes of tawny port in the nose and aftertaste. I’m a novice taster so I won’t go into more detail than that, but an interesting shift in at least this one. Certainly something I would drink again, but would actually prefer the 2012 in a couple,years.

Do tawny-port aspects indicate that an aged red wine is either declining, or damaged?
Notably, many early-1990’s California reds continue to show much more robustly than these notes.
