Olfactory perception is the sharpest of our five senses

No sensor is as powerful as the human nose. No scientific apparatus possesses such amazing abilities. Both nose and mouth are involved in tasting. We might say that the palate is in the nose, as what is perceived by the nose (smell) and retro-nasally (aroma in the mouth) blends together and complements each other.
Olfaction is the prevailing sense involved in tasting wine, coffee or whisky, accounting for 80% of tasting perceptions (remember that you can hardly taste anything when you have a cold).
