Thanks, but I don't really like rotten grape juice aka wine. I doubt anyone really does. I think its all snob appeal. Speaking of studies, do you know blind taste tests have shown people can't tell one wine from another?

DOES ALL WINE TASTE THE SAME?
POSTED BY JONAH LEHRER

On the excellent blog Marginal Revolution, the economist Tyler Cowen highlights the analysis of the Princeton professor Richard Quandt3, who found that almost of all the wines were “statistically undistinguishable” from each other. This suggests that, if the blind tasting were held again, a Jersey wine might very well win.

What can we learn from these tests? First, that tasting wine is really hard, even for experts. Because the sensory differences between different bottles of rotten grape juice are so slight—and the differences get even more muddled after a few sips—there is often wide disagreement about which wines are best. For instance, both the winning red and white wines in the Princeton tasting were ranked by at least one of the judges as the worst.

The perceptual ambiguity of wine helps explain why contextual influences—say, the look of a label, or the price tag on the bottle—can profoundly influence expert judgment. This was nicely demonstrated in a mischievous 2001 experiment led by Frédéric Brochet at the University of Bordeaux. In one test, Brochet included fifty-four4 wine experts and asked them to give their impressions of what looked like two glasses of red and white wine. The wines were actually the same white wine, one of which had been tinted red with food coloring. But that didn’t stop the experts from describing the “red” wine in language typically used to describe red wines. One expert said that it was “jammy,”5 while another enjoyed its “crushed red fruit.”

Another test that Brochet conducted was even more damning. He took a middling Bordeaux and served it in two different bottles. One bottle bore the label of a fancy grand cru, the other of an ordinary vin de table. Although they were being served the exact same wine, the experts gave the bottles nearly opposite descriptions. The grand cru was summarized as being “agreeable,” “woody,” “complex,” “balanced,” and “rounded,” while the most popular adjectives for the vin de table included “weak,” “short,” “light,” “flat,” and “faulty.”

Last year, the psychologist Richard Wiseman bought a wide variety of bottles at the local supermarket, from a five-dollar Bordeaux to a fifty-dollar champagne, and asked people to say which wine was more expensive. (All of the taste tests were conducted double-blind, with neither the experimenter nor subject aware of the actual price.) According to Wiseman’s data, the five hundred and seventy-eight participants could only pick the more expensive wine fifty-three per cent of the time, which is basically random chance. They actually performed below chance when it came to picking red wines. Bordeaux fared the worst, with a significant majority—sixty-one per cent—picking the cheap plonk as the more expensive selection.

A similar conclusion was reached by a 2008 survey of amateur wine drinkers, which found a slight negative correlation between price and happiness, “suggesting that individuals on average enjoy more expensive wines slightly less.”

These results raise an obvious question: if most people can’t tell the difference between Château Mouton Rothschild ( retail: seven hundred and twenty-five dollars) and Heritage BDX (seventy dollars6), then why do we splurge on premiers crus?

A study in the United Kingdom has found wine judges are no better than the general drinker at picking the most expensive wine in a blind taste test.

Oxford University psychologists found wine experts can judge faults in quality, and maybe the year the wine was made, but not always select the top-priced bottle.

Professor Charles Spence got Britain's top wine writers and judges to taste champagnes.

"It turned out they had no idea what the grape composition was, which sounds shocking.

"They couldn't pick the price, their preferences were just flat. So 400 pounds, $600-$700, tasted no better than a 15-pound ($30) champagne."
