The cork crumbled on extraction to about the half way point. I pushed the rest into the bottle and filtered through a fine-mesh strainer into the decanter at about 8:00 am. Poured until about 3 ounces remained in the bottle. It was a good, clean pour -- though the remaining 3 ounces were completely saturated with sediment. There was a lot of sediment in this bottle. More than I have seen in some older vintages. I poured a small amount into a glass to taste fresh from the bottle. Aromas were somewhat muted but more like a tawny than a vintage. No real fruit in this one. Color was completely orange fading to about 1/4 inch of clear rim. This appeared to be a very mature bottle. Initial taste was dominated by eucalyptus. Though the mouthfeel was a little thin, everything here was very well integrated. No heat and smooth tannins. Finish was short, but still enjoyable.
11th hour: No significant change since the intial taste in the morning. Still a little thin, short finish, strong eucalyptus. Maybe even more characteristic of a tawny than it was in the morning.
I enjoyed this, but wonder what a "younger" bottle of this might be like. My wife said that she did not enjoy it at all. She prefers the Graham's 1970, Fonseca 1963 and Dow's 1970. But, who wouldn't.
Overall score: 90 points.
Update: 2nd Day: Drinking the last of this right now, and the tannins are much more pronounced. The integration that was really saving this bottle has almost completely fallen apart. Still drinkable, but not nearly as enjoyable as the day before.
Update: 3rd Day: There was one small pour left in the decanter, so I decided to finish it off. In just a day, this seemed to pull itself back together. However, if I was tasting it blind, I would have guessed that it was a 30+ year old Colheita ... certainly not a 1977 Vintage Port.
Overall, this was a fascinating experience for me. I watched this Port evolve considerably over a 3 day period. Though it was far from what I expected, it was a thoroughly enjoyable experience. It would have made a fine Colheita
