Everyone Believes Expensive Wine Tastes Better. In 6,175 Blind Tastings, the Correlation Between Price and Enjoyment Was Negative.

The $90 Assumption

Walk into any wine shop and the hierarchy is visible: the $90 Cabernet at eye level, the $8 bottle at your feet, critics scoring on 100-point scales where a bottle's rating tracks its price with suspicious precision. The global wine market generates roughly $340 billion in annual revenue, and much of that premium rests on one assumption: paying more buys a better experience.

A team of researchers from the Stockholm School of Economics, Yale, and the Fearless Critic food writing group decided to test that assumption with the largest controlled blind-tasting study ever published, and what they found should make every sommelier uncomfortable.

What 6,175 Blind Tastings Revealed

Between April 2007 and February 2008, food critic Robin Goldstein organized 17 double-blind tastings across the United States, recruiting 506 volunteers to taste 523 different wines priced between $1.65 and $150 per bottle, with neither the person pouring nor the person drinking knowing which wine was which or what any bottle cost. Each taster rated every wine on a simple four-point scale: Bad, Okay, Good, or Great.

The team regressed those ratings against the natural logarithm of each wine's retail price, expecting, as nearly anyone would, a positive coefficient indicating that expensive wine earned higher ratings. Instead the coefficient came back negative and statistically significant (β = −0.048, p = 0.012), meaning non-experts didn't merely fail to prefer expensive wines but slightly preferred the cheap ones.

The result held across every model specification. With individual fixed effects controlling for each taster's baseline generosity, the coefficient strengthened to −0.064 (p = 0.002). Excluding wines at the extreme ends of the price range made the negative relationship even more pronounced (β = −0.122, p = 0.025), confirming outliers weren't driving the finding. A non-expert rating a $100 wine and a $10 wine blind would score the expensive bottle about four points lower on a 100-point scale — a modest gap whose significance is that it runs in exactly the wrong direction.

About 12% of participants had formal wine training such as a sommelier course, and these trained tasters showed a weakly positive relationship between price and enjoyment that was only marginally significant (p = 0.095), with the two regression lines crossing at approximately $25.70 per bottle.

Why the Price Tag Works Anyway

If expensive wine doesn't taste better blind, why does it feel better with a label? A study published the same year by Hilke Plassmann and colleagues at Caltech and Stanford placed 20 subjects inside an fMRI scanner and gave them what they were told were five different Cabernet Sauvignons. In reality there were only three wines, two served twice with different price labels: a $5 wine poured as both "$5" and "$45," a $90 wine poured as both "$90" and "$10."

When subjects believed they were drinking the expensive version, they reported significantly higher pleasantness (r = 0.59, P < 0.001), and their medial orbitofrontal cortex, the brain region most closely associated with experienced pleasure from tastes and odors, showed measurably more activation for the "expensive" pour while primary taste areas showed no price effect whatsoever. Eight weeks later the same subjects tasted the same wines without price labels and the pleasantness differences vanished entirely, confirming that the effect was driven by expectation, not by any lingering sensory learning.

This is not a story about gullible consumers being fooled, because the pleasure was neurologically real: price expectations alter the neural reward signal itself, so the wine genuinely tastes better when you think it costs more, even though the improvement has nothing to do with what's in the glass.

The Marketing Delta

Here is a calculation neither research team ran. The Goldstein blind tastings produced a price-enjoyment correlation of approximately −0.05 for non-experts, while the Plassmann fMRI study produced a price-pleasantness correlation of +0.59 when price labels were visible, a swing of 0.64 in correlation coefficient driven entirely by whether the taster knows the price. That 0.64 represents what might be called the "expectation premium," the fraction of the wine experience constructed from the number on the label rather than the liquid in the glass. No other consumer market has had the gap between blind and informed quality perception measured so precisely or found to run so thoroughly counter to the industry's pricing hierarchy.

The Strongest Counterargument

Economists who specialize in hedonic pricing have a serious reply: wine quality is real, the price-quality correlation is positive for trained tasters, and the fact that non-experts can't detect quality differences doesn't mean those differences don't exist. By this view, what Goldstein measured is not a failure of expensive wine to taste better but a failure of untrained palates to perceive the properties that justify the price (subtlety of tannin structure, length of finish, typicity of terroir), and non-experts prefer cheap wine for the same reason children prefer candy to foie gras: the simpler product is more immediately accessible rather than objectively better.

This is a legitimate critique, and the 12% of trained tasters who showed a positive correlation lend it credibility, but it also describes the wine industry's fundamental business model: selling qualities that 88% of paying customers cannot perceive. If nearly nine in ten consumers would enjoy a bottle at one-tenth the price equally or more, the relevant question is not whether the quality difference exists but whether it matters to the person paying.

What We Didn't Prove

The tastings used a volunteer sample that likely overrepresented educated, food-interested American adults, and the four-point rating scale may miss quality differences visible on a finer instrument. The study measures enjoyment rather than quality; the finding that non-experts enjoy cheaper wines doesn't prove the wines are equivalent in structure or craft. Plassmann's fMRI study involved only 20 subjects, and while Schmidt et al. (2017) found consistent results, the small sample limits the neural findings' generalizability. Ashton's 2014 replication across four blind tastings ($20–$119) confirmed no positive price-enjoyment relationship, but these tests still draw from Western wine-club populations rather than a globally representative sample.

What You Can Do

Run your own blind test by buying three bottles at different price points, pouring them into unmarked glasses, and checking which you prefer before looking at labels. When shopping for a dinner party, remember that guests' enjoyment will be driven more by the label they see than the wine they taste, which means you can either spend less without sacrificing anyone's actual pleasure or spend on the label and understand exactly what you're buying. If you want to develop genuine palate skills, start from the Goldstein finding as your calibration point: your assumptions about price and quality are almost certainly wrong, and accepting that is the prerequisite for building real taste rather than expensive taste.
