In reality, pricy bottles might not actually taste much different from cheaper wines. Your brain just tricks you into thinking it does.
University of Bonn researchers fed wine to volunteers who were lying in an MRI scanner. Before letting participants taste, the price of the wine was shown: either €3 (about $3.60), €6 ($7.17), or €18 ($21.50).
The catch? All the wine actually cost €12 ($14.34).
Even though all the wine was the same retail value, the fake price skewed how the volunteers thought it tasted, according to study results in the journal Scientific Reports. “As expected, the subjects stated that the wine with the higher price tasted better than an apparently cheaper one,” co-author Hilke Plassmann, PhD, said in a statement. On average, they rated the most expensive wine a 5.21 out of 9, but the cheap wine got just a 4.19 rating. (Before you sample your next glass, brush up on these wine terms you need to know.)
Taking a peek at the brain scan results, the researchers noticed something interesting. A part of the brain that deals with decision-making and expectations, and a part involved with the reward and motivation system both lit up more for the supposedly pricier wines. “Ultimately, the reward and motivation system plays a trick on us,” co-author Liane Schmidt, PhD, said in a statement. Your brain expects expensive wine to be better quality, so you judge the flavor as better—even if it actually tastes the same as a cheaper bottle.

And your brain isn’t just trying to make you feel better about spending so much on a bottle of vino. In some parts of the study, participants “paid” for their sips with a set amount of money the researchers gave them before the start. But whether volunteers saw their accounts dwindling or not, the more expensive bottles tasted better. So a pricy bottle your best friend brings for dinner would taste just as good as one you shelled out for yourself.
Interestingly, a low price tag might skew your perception more than a pricy bottle. A week after the fMRI session, researchers asked participants to sample the $14 wine without knowing the price. When they blindly sipped the wine, participants gave a rating of 5.03—closer to the rating they gave the expensive bottle. Apparently, your low expectations of a cheap bottle will affect your taste buds more than the way you look forward to a quality expensive wine. So when it comes to cheap wine, what you don’t know won’t hurt you.
