That's probably true, to some extent at least - the people who go for more upmarket stuff (excluding those who are just buying something expensive to look flash) are quite likely to be looking for some more complex flavours that tend to develop more with age (of the wine, that is!). Unfortunately a lot of the premium wine gets sold when it's nowhere ready to drink, on the assumption that you'll buy it and stick it away in a cellar somewhere to mature - if you drimk it too soon it may not impress, and very likely won't seem worth the difference in price. I just spent a couple of hours tasting wines (mainly from 2009) that were put up by a well-known merchant, and somewhat depressingly I found when I looked at the price list that there did seem to be a fairly strong correlation between how much I liked the wine and the price, even if there were a few which lay well above the curve, and some which were rather below. Unfortunately the one I really liked was way beyond what I wanted to pay, at =A3800 per dozen! I suspect when you get to that level you pay quite a lot more for a small improvement, because of the scarcity value - rather like the improvement between a car costing =A3100k and one costing =A3200k...
