How it works: To explain briefly, our brain distinguishes between orthonasal (perceived via nose) and retronasal (perceived via mouth) scent. While orthonasally perceived smell is also interpreted as such by our brain, retronasally perceived scent is interpreted as a part of our taste impression and our brain attributes it to food or drinks in our mouth. The idea is simple: you fill still or sparkling water into the Flavour water bottle, select your favorite taste, and put the flavour pod on the head part. Sucking on the silicone attachment creates a suction that not only transports the water but also air from the outside through the fragrance pod into the mouth. This is where retronasal olfaction comes into play: in the throat, the flavored air rises from the water and is perceived as taste at the olfactory center. So technically, users tricked their brain and saved their body from proven harmful sweeteners, stabilisers, or acid regulators.
