Basic knowledge of sensory training in coffee tasting tongue taste area distribution map

With regard to taste maps, coffee and red wine are often used in tasting.

Taste refers to the ability to sense the taste of substances, including the taste of food, certain minerals and toxic substances, which is close to the sense of smell, which is also chemically induced. Western experts have traditionally believed that taste consists of four basic flavors: sweet, salty, sour and bitter (note: no "spicy", spicy is the feeling!). On the other hand, experts in the East have identified the fifth flavor-fresh taste. Recently, psychophysics and neurology suggest that taste includes other elements (freshness, the fatty acids we can feel most, as well as the taste of metal and water, although the latter is often ignored because of the adaptability of taste).
