Your Olfactory System at Work When Wine Tasting

We often focus on the flavours and textures that address our palates in wine tasting. However, there's another unsung hero in the act of tasting – our olfactory system. Yep, those little nostril receptors that make or break what we smell and taste.

The Importance of the Olfactory System

The human olfactory system, composed of the nose and the brain, is a powerful tool that detects and distinguishes thousands of scents. When it comes to wine, the aromas released during the swirling and sniffing stages are not just pleasant fragrances; they are the key to unlocking the nuances within each bottle. As such, the olfactory system plays a crucial role in wine tasting, contributing to 80% of wine perceptions. Simply put, the olfactory system acts as a gatekeeper, priming our taste buds and enhancing our ability to discern the distinctive features in the wine.



Your olfactory receptors are a group of ciliated cells that reside in your nostrils. They are responsible for kicking your olfactory into gear. If they are not working, you cannot smell aromas or taste. If you've ever wondered why you could not taste the flavours of food when you have a cold, this is why. Your olfactory system and receptors cannot work as intended, given your stuffy nose and inherent lack of ability to smell.


Wine can contain over a thousand volatile compounds; fittingly, the sense of smell, or olfaction, allows individuals to detect a wide range of aromas and flavours. Of course, combining many compounds creates the aromas perceived when smelling a glass of wine, adding to its complexity.


Additionally, neuroscientific studies have shown that the brain plays an integral role in creating the taste of wine, and the olfactory system is responsible for smell - ultimately, the wine tasting experience in a package. What you smell translates to the palate and tells it the flavours to expect, even before tasting the wine!


Your olfactory system is the unsung hero, leading you through each bottle's aromatic intricacies. Therefore, understanding the importance of the olfactory system is essential for fully appreciating and evaluating the complex flavours and aromas present in wine.
