Taste, gustatory perception, or gustation is one of the five traditional senses. Taste is the sensation produced when a substance in the mouth reacts chemically with receptors of taste buds. Taste, along with smell and trigeminal nerve stimulation (which also handles touch for texture, also pain, and temperature), determines flavors, the sensory impressions of food or other substances.

In specialty coffee, taste an flavor of coffee are very important. The whole coffee bean production and preparation chain focuses on preserving and revealing the origin of the beans.
