Derek wisely included the phrase, "from the showing of this bottle." Often times, people who have just tasted a bottle of Port will discuss/argue that their impression from the bottle they just tried is the way the wine typically shows.I would say that from the showing of this bottle the Dow 1977 is in the zone for drinking now and I find it difficult to see any reason why it would improve further.
I think that Derek chose his words wisely here, showing his previous experience with 1977 Dow. Typically, it is young and vibrant and will age very well for a few decades. But Derek was describing his experience with this particular bottle. Herein lies the benefit of multiple tastings of the same VP.
Although I am only assuming that Derek has had the '77 Dow on several occasions (I am sure he'll be by to let us know the reality of this assumption) the best thing we can all see from his example is that you can not make a judgement about a producer or vintage or even the combination thereof, solely based on one bottle ... even if it is tasted at the source.
Does that mean that TNs are meaningless? Heck no, but they are a snap shot view (longer if tasted and described over a longer period of time) and not necessarily representative of other bottles of the same Vintage/Producer. Another example was Alex B.'s recent commentary on my 1966 Fonseca from a flawed bottle (used by Vinfolio) compared to my other TNs on the same wine from pristine bottles.
