Well, on the one hand, you can trust the Pro's - Parker, Tanzer, Meadows, Schildknecht - and their opinions.
[Although Schildknecht, to his credit, has been honest enough recently to admit that wine evolution in bottle is such an incredibly complex phenomenon that he doesn't anymore even trust his own judgment about predicting drinking windows.]
Personally, I place a great deal of faith in "time to oxidation" - I like to follow a bottle over the course of five days or more, waiting to see how long it takes for the wine to oxidize.
If it's completely dead on "Day Two", then it's not something I'm interested in pursuing.
BTW, flaws like TCA, "metallic" Brett, residual sugar masquerading as fruit [which is a good thing in some wines, but a bad thing in others, such as ostensibly dry whites], etc, are much easier to detect on Day Two [and thereafter] - when you first open a wine on Day One, it can strike you as being a little strange, but often you won't be able to figure out what's wrong with it until Day Two, when the flaws will suddenly be transparently obvious.
The other great thing about tasting before buying [in bulk] is that you get a better sense of the provenance of the wine - in general, you guys in the UK probably don't have as much of a problem with heat damage as we have in the USA, but if you taste in small quantities before buying in bulk [from the same source], then at least you will know that you aren't purchasing vinegar [which can be huge problem here in the USA].
Anyway, at some point you have to place some faith in yourself: If you enjoy the wine, if you've studied it amply [to make sure that it doesn't suddenly fall apart and become disgusting soon after opening], and if it's priced aggressively - i.e. if you've tasted other wines of its ilk, and if it stands out among its peers as being a special value - then don't lose any sleep over purchasing it.
