Can a short test predict
the wines you prefer?

ENOMATCH · WINE PREFERENCE PREDICTION METHOD

EnoMatch explores the relationship between your everyday taste preferences and the sensory characteristics of the wines you enjoy. We are developing a study to assess how well the method predicts preferences, and where its limits lie.

Take the questionnaire to discover your Enotype and contribute to the preliminary phase of the project.

One method. Three indices.

The EnoMatch Method brings together a consumer score, a wine score and a measure of how closely they match.

Index What it represents
ENOTYPE · Consumer Sensory Index Your score calculated from a 20-question test, on two scales from 0 to 100: S (Structure) & B (Balance).
WINETYPE · Wine Sensory Index A wine’s S & B scores, calculated from alcohol content, tannicity, acidity, CO₂ pressure and sugar concentration. They also range from 0 to 100.
AFFINITY · Matching Index The numerical closeness of your Enotype to a wine’s Winetype, expressed as a percentage.

The questionnaire focuses on preferences and experiences with flavors and sensations in the mouth. It does not assign personality traits. The aim is to support wine choice, not to rank people’s palates or knowledge.

How does EnoMatch work?

The consumer’s two coordinates are calculated from indices derived from the questionnaire:
\[S_E=0.30\,TN_E+0.70\,AL_E\]
\[B_E=30+0.70\,AC_E-0.30\,SW_E\]
TN reflects estimated preferences related to tannic sensations; AL, to alcoholic sensation; AC, to acidity; and SW, to sweetness. These indices come from questionnaire answers, not physiological measurements. We compare the Enotype and Winetype using a weighted distance:
\[d=\sqrt{0.60\,(S_E-S_W)^2+0.40\,(B_E-B_W)^2}\] \[\mathrm{Affinity}=100-d\]
Both profiles use the S and B axes, but Balance is calculated differently for wine and consumers. We are evaluating how useful this proximity is for anticipating real wine preferences. Learn about the method and study design

Two scales & five profiles

The two S/B values place each Enotype and Winetype on a map.
Four outer zones represent combinations of structure and balance, while Neutral occupies the central square.

Light

Lighter structure and a tendency towards fresher, more tart sensations.

Bold

Greater structure and a preference for more pronounced acidity.

Smooth

Lighter structure and a gentler balance, less oriented towards acidity.

Rich

Greater structure and a gentler balance, less oriented towards acidity.

Neutral

Intermediate structure and balance.


These are model categories, not grades of quality, expertise or wine knowledge. No profile is better than another.

We want to find out whether the questionnaire score is associated with the styles of wine people say they prefer and, in a later phase, with the wines they select in a blind tasting.

The online phase gathers questionnaire responses and a separate statement of wine preference. The planned tasting will compare the model’s predictions with participants’ ratings and choices, without showing the wine’s brand or price.

Our question is not whether two numbers can be made to look similar. It is whether the method provides useful information beyond a non-personalized recommendation.

Comparison

Planned study design

The planned validation will compare the questionnaire score with the preferences observed during the tasting.

Your preferences can help us investigate

We invite adults aged 18 or over who already drink wine, including both consumers and wine professionals, to contribute their experiences. You do not need wine expertise or any products to taste while answering.

Complete the questionnaire, tell us which style of wine you usually prefer, and then see your Enotype score and category. Taking the online test does not automatically register you for a tasting.

The method is under evaluation. Your result is an indication based on your answers. Affinity describes numerical proximity, not a validated probability that you will like a wine.
