We all have that one friend. He spends 10 minutes analyzing the wine menu, he asks the sommelier a ton of fancy-sounding questions about each vintage, and he always gravitates toward the more expensive bottles, in an attempt to impress everyone at the table with the extravagance of his tastes.

We naturally want to believe that there is a deep science to this friend’s obsession with fermented grapes. But as someone who can barely even tell the difference between a merlot and a warm chardonnay with my eyes closed, I couldn’t help but wonder: Is this all bullshit? Is expensive wine worth it?

It was time to get scientific. So my wife, Adrienne, and I decided to host a blind wine tasting experiment where we attempted to settle this question once and for all. Can our wine-loving friends tell the difference between the taste of an expensive bottle and a lower-priced bottle of wine?

The expensive wine experiment

The first step in conducting this study was to determine which wines to use. Our friend Suzanne—an experienced, self-identified “wino” and aspiring sommelier—helped us select a group of 12 wines (6 varietals x 2 options each) that would present the most representative low-priced and expensive choices for the varietals in question.

For each varietal, we purchased one representative “expensive” bottle ($40-60), and one representative standard/best-value bottle ($10-15) from the same region and roughly the same year. We then cloaked the bottles with an opaque canvas bag and labeled them with their varietal and the letter A or B (i.e. Pinot Noir A, Pinot Noir B, etc.). Telling attendees which varietal they were tasting eliminated any external confusion and helped us focus on nothing but the level of perceived “quality” for each option.

All attendees then poured themselves a glass from each bottle and tasted the varietals one pair at a time. They were asked to evaluate, on the “palate ballot” below, which of each varietal that they thought was the more expensive wine.

The results

We announced the results at the end of a delicious dinner that Adrienne prepared for our guests.

Across all 14 of our wine tasters, the average grade was about 55% correct, or barely better than if they had just randomly selected A or B across the board! Not a single person got all 6/6 correct. At first glance, it would thus appear that wine snobbery is, indeed, bullshit.

However, it should be noted that our four friends who have most seriously studied wine in the past were precisely the four people who scored highest on the test (with scores of 4/6, 4/6, 4/6, and 5/6). And in most of those cases, the only ones they missed were the two varietals of white wines, which everyone agreed were the most difficult to tell apart (likely because they are served chilled).

We can therefore state the following: For people who have spent years developing a highly refined wine palate, it may indeed be worth it to purchase the more expensive bottle (for red wines at least). But for most of us mere mortals, a decent $15 bottle will probably taste just as good as a $50 bottle.

This seems to be consistent with the research: in general, more expensive wines do taste better ... but most people aren't very good judges of wine.

The only remaining caveat is to remember that there is more to wine enjoyment than just taste. Wine aficionados can also derive emotional value from the story of the vineyard, the science behind the particular fermentation technique, and/or the branding and marketing that they may have been exposed to. Whether those intangible values are worth paying more than 4 times as much money is a matter of personal preference.

Conduct your own experiment

Finally, in case you are interested, below is a list of the actual wines we used in this experiment. Wherever possible, we tried to select the most “representative” standard vs. expensive versions of each varietal, keeping them within the same region and roughly the same vintage wherever we could.

We recognize that some readers may object that the higher-end bottles we chose were not “expensive” enough. “If you’d chosen a $100 bottle,” some of our own attendees assured us, “then I totally could have told the difference.”

If that sounds like you, then by all means, please buy those expensive wines and replicate this experiment yourself! We’d love to hear the results.
