1994's closed? Alex, you are scaring me as this sounds way too much like a guy named Andy V. who has been saying this for a year or two now.
It is certainly possible. I know you've read the brilliant responses to the "Port shut down" in the A QUESTION FOR THE PORT TRADE area of the newsletter a few months ago when the shippers added their opinions about this issue.
Then again, what is a rather small possibility is: the "WNFH Syndrom" (aka the: Wine Night From Hell). It has only happened to me a handful of times in my 30 years of drinking wine ... but each is memorable. This happens, not with a rare example of MANY cork infested bottles, which is maddening in itself ... but when an entire group of wines and only in 1 case, Port wine ... just absolutely fail to deliver what is expected of them from previous experience ... and appear not to drink nearly as well. It is a strange phenomenon that can not be explained. Sometimes, and I am not joking here, it can be a disturbance in a weather pattern and especially high or low barometric pressure or extremes in temps ... however, a couple of these WNFH had nothing to do with either.
For example, a Dominus vertical tasting ... where not one of our 8 tasters in my STG (Seattle Tasting Group) which includes the likes of Eric LeVine (CellarTracker) and other well know local winos ... where not a single bottle was within 3-5 points of its typical range. I brought the 1991 Dominus that night. It is one of the all-time greats in terms of ANY CA wine ever made. I have substituted this as a "blind ringer" in some very high end Bordeaux tastings with friends and winemakers who were 100% fooled and could not tell it was a domestic wine ... even once they were shown the unsheathed bottle. On the WNFH it was not corked and not seemingly defective but only had 70% of its normal greatness appear. I was blown away, but then again the 1994 and 1997 and 2001 ... none of these delivered either. These are all extraordinary wines. Lesser great vintages like 1992 and 1995 also did not provide nearly what we had all grown accustomed to.
I have had this happen four or five other times. With Port, maybe once or twice. Thinking of a recent example (although there was a heat wave here) we had a bunch of fantastic Ports in our lineup recently when Oscar was in town, going back to a sound 1937 Colheita. But in general, with Ports (VP & Colheita) we've all mostly had before that night ... nothing was showing as it typically had in the past. It happens and there's no explanation. Yes there was a heat wave, but we had rented an air-conditioned room to drink in. Nobody traveled any further than 45 minutes and half of us were within 10 miles of the venue. These type of anomalies just have no rhyme or reason. Reading your comment, I just wondered if you had fallen prisoner to one of these types of WNFH?
I am certainly avoiding insisting that 1994's could not possibly be shutting down ... I just can't bear to listen to Andy's ... "I told you so."
