The world of wine, rich in nuances, aromas, and stories, is not limited to tasting. Our perception of it, particularly during tasting, is profoundly influenced by an often underestimated factor: color. Gabriel Lepousez, a renowned neurobiologist specializing in sensory perception, reveals how the magic of the visual guides our taste judgments. Between psychology, evolution, and neurobiology, he sheds light on a fascinating phenomenon: our brain, programmed to favor visual information, tends to perform wonders of interpretation that shape our experience of wine, whether it’s a complex Bordeaux or a sparkling MoĂ«t & Chandon Champagne. In a world where the sophistication of tasting is increasingly valued, understanding this influence not only allows us to refine our sensations, but also to overcome our biases to fully appreciate the sensory richness offered by each bottle. Science, combined with a passion for wine, opens a door to a universe where color becomes a true language of our perceptions, shaping our preferences and memories. In 2025, this knowledge also offers new perspectives for oenology, blind tasting, and the promotion of Provence wines or fine wines like Château Lafite Rothschild.
How the color of wine conditions our perception: a neurobiological dive
The role of sight during tasting isn’t simply aesthetic. In fact, it influences our expectations, our physiological reactions, and even the way our brain processes other sensations. The color of wine, whether that of an elegant Château Margaux or a more vibrantly hued Provence wine, acts as a primary filter. It guides our perception of texture, aromas, and even perceived quality.
According to Gabriel Lepousez, in the era of evolution, sight quickly surpassed our other senses: with the emergence of homo sapiens, a major adaptation occurred to prioritize vision. Today, it activates approximately 15% of our cerebral cortex to process visual information, compared to barely 1% for smell or taste. This hierarchy explains why a color colors our judgments—for example, a dark color will often evoke greater complexity than a pale color, even if their content is identical. Perceptual Criterion
| Cognitive Response | Example | Wine Color |
|---|---|---|
| Creation of Flavor and Texture Expectations | Deep Red Wine = More Tannic Tasting | Background Sound or Environment |
| Modification of Olfactory and Taste Perception | Soft Music Accentuates the Perception of Finesse | Visual Body of the Glass |
| Influence on Wine Appreciation | Thin and Elegant Glass = More Sophisticated Experience | This visual bias is so powerful that it even influences objective judgment during professional tastings. Laboratory experiments have shown that a wine presented with a light color can be judged less complex than a wine of the same composition with a darker hue, simply because of the expectation generated by the color. |
The Effects of Color in Blind Tasting
An iconic experiment conducted by Gabriel Lepousez and his colleagues demonstrates that the perception of a wine can be completely altered by changing its perceived color, regardless of its true organoleptic qualities. During a blind tasting, combined with a chromatic manipulation, participants believed they were tasting a red wine when it was actually a white wine with a red tinge. The majority described flavors of red fruits, tannins, or length on the palate, guided primarily by the liquid’s hue.
This influence raises many questions: the future of neuroenology, how sensory perception can be diverted or amplified, and how certain great estates like Château Lafite Rothschild or Domaine Leflaive could optimize their image through chromatic tricks.

This neurological process also explains why our cultural values ​​play an important role: associating certain prestigious estates, such as Domaine de la Romanée-Conti, with intensely colored wines, reinforces this perception through cultural bias. Memory and emotion are intertwined, guiding our preferences and judgments.
Brain Area
Function
| Implication for Tasting | Orbitofrontal Cortex | Evaluation of Integrated Sensory Quality |
|---|---|---|
| More Favorable Perception of a Deep Red Wine | Fusiform Gyrus | Visual Color Recognition |
| Association of Hues with Nobility and Complexity | Hippocampus | Collection of Olfactory and Taste Memories |
| Reinforces the Subjective Experience Depending on the Cultural Context | The Influence of Culture and Wine History | The perception of wine is also a cultural experience, informed by the history of each wine-growing region. For example, in Bordeaux, the dark color and full-bodied appearance often evoke power and tradition, while in Champagne, transparency and lightness invite celebration and delicacy. Great wines like Château Lafite Rothschild or Domaine Leflaive benefit from a reputation built on centuries of history, enhanced by their visual appearance. In this sense, color goes beyond a simple aesthetic; it becomes a symbol of prestige, terroir, and expertise. |
This cultural dimension can also explain why certain wines, even of equivalent quality, are perceived differently depending on their provenance. Color then becomes an element of storytelling, influencing both novice consumers and expert winemakers.

Concrete influence on marketing strategy and professional tasting
In tastings, the trend is toward highlighting color to enhance a vintage or mask certain flaws. Chromatherapy, or the optimized use of color, also allows for emotionally-driven marketing strategies, especially in the context of the phenomenon of minimalist or “natural” wine labels. Marketing Objective
Strategy Employed
Example
| Arouse Desire | Sophisticated Label Design with Noble Colors | Chateau Margaux or Château Mouton Rothschild |
|---|---|---|
| Influence Tasting Perception | Use of Specific Glasses or Presentation Colors | Hot or Cold Glass to Modulate Color Perception |
| Highlight the Terroir | Choice of Colors to Reflect the Region | Provençal Wines in More Vivid and Bright Colors |
| This work, which combines science and marketing, shows that visual perception is not only used for aesthetics, but also becomes a true strategic weapon in showcasing wines. A deep understanding of these mechanisms offers a significant advantage in optimizing presentation and consumption, making wine an object of art as much as an object of emotion. | https://www.youtube.com/watch?v=sYLA6U1boF8 | FAQ – Understanding the Impact of Color on Wine Perception |
Can color really change the perceived flavor of a wine?
How do great estates exploit this influence?
- They often prioritize the visual presentation of their bottles, using noble colors, elegant labels, or even chromatic techniques to reinforce the impression of superior quality. Is it possible to counteract this influence for an objective tasting?
- Yes, particularly through blind tasting, where the perception of color is masked, allowing for a more accurate appreciation of the organoleptic qualities. Do wines like Château Margaux or Domaine de la Romanée-Conti also influence visual perception?
- Naturally, their presentation, deep color, and terroir are reflected in their color, thus reinforcing their prestigious image. Source: www.lemonde.fr
