The Truth: Wine experts and consumers can be fooled by altering their expectations.
You scan the aisles in the liquor store looking for a good wine. It's a little overwhelming -- all those weird bottle shapes with illustrations of castles and vineyards and kangaroos. And all those varieties? Riesling, Shiraz, Cabernet -- this is serious business. You look to your left and see bottles for around $12; to your right you see bottles for $60. You think back to all the times you've seen people tasting wine in movies, holding it up to the light and commenting on tannins and barrels and soil quality -- the most expensive wine has to be the better one, right?
Well, you are not so smart. But, don't fret -- neither are all those connoisseurs who swish fermented grape juice around and spit it back out.
Wine tasting is a big deal to a lot of people. It can even be a professional career. It goes back thousands of years, but the modern version with all the terminology like notes, tears, integration, and connectedness goes back a few hundred. Wine tasters will mention all sorts of things they can taste in a fine wine as if they were a human spectrograph with the ability to sense the molecular makeup of their beverage. Research shows, however, this perception can be hijacked, fooled, and might just be completely wrong.
In 2001, Frederic Brochet conducted two experiments at the University of Bordeaux.
In one experiment, he got 54 oenology (the study of wine tasting and wine making) undergraduates together and had them taste one glass of red wine and one glass of white wine. He had them describe each wine in as much detail as their expertise would allow. What he didn't tell them was both were the same wine. He just dyed the white one red. In the other experiment, he asked the experts to rate two different bottles of red wine. One was very expensive, the other was cheap. Again, he tricked them. This time he had put the cheap wine in both bottles. So what were the results?
The tasters in the first experiment, the one with the dyed wine, described the sorts of berries and grapes and tannins they could detect in the red wine just as if it really was red. Every single one, all 54, could not tell it was white. In the second experiment, the one with the switched labels, the subjects went on and on about the cheap wine in the expensive bottle. They called it complex and rounded. They called the same wine in the cheap bottle weak and flat.
Another experiment at Cal-Tech pitted five bottles of wine against each other. They ranged in price from $5 to $90. Similarly, the experimenters put cheap wine in the expensive bottles -- but this time they put the tasters in a brain scanner. While tasting the wine, the same parts of the brain would light up in the machine every time, but with the wine the tasters thought was expensive, one particular region of the brain became more active. Another study had tasters rate cheese eaten with two different wines. One they were told was from California, the other from North Dakota. The same wine was in both bottles. The tasters rated the cheese they ate with the California wine as being better quality, and they ate more of it.
So is the fancy world of wine tasting all pretentious bunk? Not exactly. The wine tasters in the experiments above were being influenced by the nasty beast of expectation. A wine expert's objectivity and powers of taste under normal circumstance might be amazing, but Brochet's manipulations of the environment misled his subjects enough to dampen their acumen. An expert's own expectation can act like Kryptonite on their superpowers. Expectation, as it turns out, is just as important as raw sensation. The build up to an experience can completely change how you interpret the information reaching your brain from your otherwise objective senses. In psychology, true objectivity is pretty much considered to be impossible. Memories, emotions, conditioning, and all sorts of other mental flotsam taint every new experience you gain. In addition to all this, your expectations powerfully influence the final vote in your head over what you believe to be reality. So, when tasting a wine, or watching a movie, or going on a date, or listening to a new stereo through $300 audio cables -- some of what you experience comes from within and some comes from without. Expensive wine is like anything else that is expensive, the expectation it will taste better actually makes it taste better.
In one Dutch study, participants were put in a room with posters proclaiming the awesomeness of high-definition, and were told they would be watching a new high-definition program. Afterward, the subjects said they found the sharper, more colorful television to be a superior experience to standard programming. What they didn't know was they were actually watching a standard-definition image. The expectation of seeing a better quality image led them to believe they had. Recent research shows about 18 percent of people who own high definition televisions are still watching standard-definition programming on the set, but they think they are getting a better picture.
In the early '80s, Pepsi ran a marketing campaign where they touted the success of their product over Coca-Cola in blind taste tests. They called this the Pepsi Challenge. Psychologists had already determined you choose your favorite products often not by their inherent value, but because the marketing campaigns and logos and such have cast a spell over you called brand awareness. You start to identify yourself with one marketing campaign over another. That's what happened in the all the taste tests up until the Pepsi Challenge. People liked Coca-Cola's advertising more than Pepsi's, so even though they tasted pretty much the same, when they saw that bright red can with a white ribbon people chose Coke. So for the Pepsi Challenge, they removed the logos. At first, the researchers thought they should put some sort of label on the glasses. So, they went with M and Q. People said they liked Pepsi, labeled M, better than Coke, labeled Q. Irritated by this, Coca-Cola did their own study and put Coke in both glasses. Again, M won the contest. It turned out it wasn't the soda; people just liked the letter M better than the letter Q.
You look for cues from our environment whenever you find things you like. These clues help you to get back to the good stuff by recognizing the cues that got you the reward last time. For the testers, the two products tasted pretty much the same. So, forced to make a choice, they moved to another set of cues to make their decision -- which letter was more pleasant. Apparently, M is better than Q, and in other research people tend to pick A instead of B and 1 instead of 2. Branding works the same way. Vodka, for instance, has no flavor. So advertisers can't sell you on how great it tastes. Instead, they hijack your natural affinity for visual shortcuts by pummeling your brain with advertising. When you are standing in front of all those vodka bottles in the liquor store, the brands hope their marketing campaign has built enough expectation in your consciousness to lead you to their product.
In blind taste tests, long-time smokers can't tell their brand from any of the competitors and wine connoisseurs have a hard time telling $200 bottles from $20 ones. When presented microwaved food from the frozen food section in the setting of a fine restaurant, most people never notice. Taste is subjective, which is another way of saying you are not so smart when it comes to choosing one product over another. All things equal, you refer back to the advertising or the packaging or conformity with your friends and family. Presentation is everything.
Restaurants depend on this. Actually, just about every retailer depends on this. Presentation, price, good marketing, great service -- it all leads to an expectation of quality. The actual experience at the end of all this is less important. As long as it isn't total crap, your experience will match up with your expectations. A series of bad reviews will make the movie worse, and a heap of positive buzz can sway you the other direction. You rarely watch films in a social vacuum with no input at all from critics and peers and advertisements. Your expectations are the horse, and your experience is the cart. You get this backwards all the time because you are not so smart.
