Gustation, also known as “taste” is the ability to sense the general chemical composition and classification of substances through direct sampling or “tasting”.

The primary organ for taste is the tongue. The tongue allows chemical composition and classification of substances through direct sampling via specialized and different chemical receptors called gustatory calyculi (taste buds) on the upper surface of the tongue converting the chemical reaction into specialized electrical impulses to different parts of the brain depending on a primary type of taste or more refined sense of taste if the sense is trained to do so.

Homo Sapiens possess six (6) primary types of taste exist being sweetness, sourness, bitterness, saltiness, spiciness and savoriness.
