As important as tasting blind can be, I think that tasting over the course of several days [to follow the oxidation curve] might be even more important.
These 30-second snapshots of a wine, taken within the context of a 100+ bottle mega-tasting, are essentially useless.
Not only is the critic’s palate completely shot at the end of the first half hour or so, but his temporal experience with the wine is so brief that his predictions for the evolution of the wine tend to be kinda silly after about six months [and from the very outset as regards performance on Day Two].
I read somewhere that Stuart Piggott once declared that he would no longer publish a review of a wine until he had had the opportunity to drink an entire bottle of it [and study its evolution] - and while I don’t know whether he stuck to that pledge, in general, it’s the sort of study of the wine that you need to make for your review to have any long-term merit.
PS: Parker - to his credit - does invest this kind of effort into reviewing the 1st & 2nd Growths in Bordeaux. The problem is that he never put the same sweat equity into his Australian and Spanish reports.
PPS: Speaking of Spain - another significant problem is the cherry-picking of the bottle samples that are [or were] presented to Parker, and then, after the big scores are published, the placement of subsequent orders for the wine which are filled at the winery with inferior juice bottled under the same label.
If the juice the critic reviews is not the same as the juice the importer ships under that label, then obviously the review is simply worthless.
PPPS: I was reading recently where Parker had told Rovani that “to keep your chops up” you had to taste every day of the year - that if you even took off Christmas Day or New Year’s then you would start to lose your edge.
But I honestly don’t know how you can keep up that kind of tasting schedule and not lose your palate rather quickly.
[And probably put yourself at significantly increased risk of developing cancers of the mouth and the throat.]
