Sensory scientist Qian Janice Wang said how brain processes determine wine perception during a TEDxNoVA presentation in Northern Virginia [1].
This research challenges the notion of a universal tasting standard by suggesting that the experience of wine is subjective. Understanding these neurological drivers helps explain the gap between how experts and beginners perceive complexity.
Wang said that no two people taste wine the same way and that science is beginning to show the reasons for these differences [1]. The presentation focused on the interaction between the chemical components of the wine and the sensory processing of the human brain.
Wang said the quality of a wine is not solely dependent on the liquid in the glass. She said that what makes a wine great may have less to do with the contents of the glass and more to do with what is happening in the brain [1].
The talk, recorded on Oct. 10, 2025 [1], explored how the brain interprets various sensory inputs to create a cohesive experience. This process differs significantly based on the individual's neurological makeup and level of expertise.
Wang said the goal of winemaking is the effort to harness complex components into a seamless and harmonious expression where no single element dominates [1]. This harmony is then processed by the brain, which varies from person to person.
“No two people taste wine the same way, and science is starting to show us why.”
The shift toward a neurological understanding of taste suggests that 'objective' wine quality is a misnomer. By centering the brain rather than the bottle, this research moves wine tasting from a purely agricultural or chemical study into the realm of cognitive science, implying that training and biology are the primary filters for quality.
