Difficult to score, though. I'm fairly sure it had been tainted by reacting with the metal cap during its almost 50 years in the bottle, but it retained an undeniable beauty.
Hmmm - opens weird, with strong a meaty/metallic note. This starts to fade almost immediately, and eventually disappears altogether, but the process takes about an hour. As it falls away, it's progressively replaced by a bright, crisp old-fashioned sherry aroma, with polished wood. The complexity grows, with fruity/spicy/nutty impressions fighting their way into the foreground. Quite a dramtic development, all told!
The off note is transmitted from the nose, but it has less impact here. Starts slightly bitter, pleasantly sharp, with a hint of smoke. Dark fruits and nut oil. Good weight, mouth-coating. Struck match towards the end.
Short, clean, slightly drying, sweet and sour.
