Detecting aromas in whisky – Chapter 1
Olfaction is one of the five human senses: it allows us to detect and perceive odorous molecules, through our nose but also through our mouth. Olfactory receptors are the keystone to olfaction.
Everything begins with a volatile molecule that travels to our nostrils to reach the olfactory receptors. Once bound to one (or several) receptors, the molecule activates a kind of switch that starts the creation of a mental image for the smell in the brain. Finally, our sense of smell is subject to the complex phenomenon of molecular synergies: combined together, odorous molecules may interact and therefore intensify, reduce, or even create a new smell.
