Purchased when released (~2004, $21). Cellared at constant 57' F (offsite).
Muted, almost absent of any nose, and acidic tasting immediately after being uncorked. Suspected that wine was defective or dead, but decided to decant. Improved over 3+ hours of time in the decanter and in the glass through airing. Looks like it was "sleeping" or going through an awkward period. Black and blue berries emerged over time, with soft and judicious oak as its frame. However, the wine remained disjointed and angular. Will leave half of a bottle in the decanter for a re-tasting in 24 hours. Will update tasting note.
[Update]: A day later...the wine remained out of balance and acidic. I'm attributing this to bottle-to-bottle variance. Will try another bottle in the near future and compare tasting notes.
