Anatomical map of the growth environment of coffee beans-how to distinguish between good and bad coffee beans

Coffee is grown with seeds with endocarp, and the raw coffee beans we usually come into contact with have their endocarp removed, so they can't be planted.

Endocarp ("sheepskin" or "paper skin") refers to the tea-brown hard skin that wraps the coffee seeds, and the coffee beans attached to that layer are called "shelled beans" ("sheepskin paper beans").

Generally speaking, there are two pairs of seeds in the fruit, but occasionally there is only one seed in the fruit, which is called Pea berry.

The coffee we usually drink is made by grinding, brewing and other steps after roasting the seeds at the center of the coffee fruit.

Coffee fruit is mainly transformed into raw coffee beans by the following three treatments: dried, washed and semi-washed.

Coffee flowers are white in color, fragrant jasmine, withered in about 3-4 days, and 6 petals (5 male and 1 female, split into two at the front end). The cotyledon tip of coffee is pointed, the two pieces are relatively grouped, the leaf surface is dark green, the back is light green, oval.

The higher the growth height of coffee beans, the higher the acidity. The price of coffee beans is higher than that of coffee with proper sour taste, such as Blue Mountain Coffee, which has a natural balance of sour, sweet and bitter taste and full flavor. The natural price is also high on the structure of coffee cherries and the classification of coffee beans:

Coffee beans are fresh and green raw beans obtained by removing their red flesh, peel and silver skin from coffee cherries. The structure of coffee cherry is exocarp, pulp, endocarp, silver peel and seed from outside to inside. Coffee cherries are oval in shape.

Coffee beans can be divided into round beans and flat beans, round beans refer to a coffee cherry, usually have two coffee beans, but some have only one because of incomplete embryonic development, that is, round beans, which are oval in shape. Flat bean refers to a coffee cherry, usually the fruit of coffee is composed of two oval seeds, because its joint is flat, it is called flat bean.
