When you buy coffee beans, you should not only look at the brand information, but also pay special attention to its origin.

The general process of coffee production

The production process of coffee beans:

1. Find the coffee tree in the place of origin and pick the coffee fruit from it.

2. Peel off the peel and pulp of the picked coffee fruit after sun or water washing, and get the raw coffee bean.

3. Roast raw coffee beans and get different grades of cooked beans according to different techniques.

Origin of coffee beans:

Coffee beans are processed from the fruits of coffee trees and are generally grown in tropical and subtropical regions. The best quality coffee beans in the world are produced in Indonesia and Colombia. In terms of production, Brazil ranks first in the world's output, accounting for about 30%, followed by Colombia-centered Central and South America, followed by Africa and Arabia, and the remaining 10% are distributed in Asia and the islands.

Different grades of coffee beans can be produced by different roasting techniques and time, such as drum baking and hot air baking:

Generally speaking, if the frying time is short, the color of the coffee beans will be light brown and sour; if the fried tones are dark, the bitterness will be enhanced and the color will be dark brown. Therefore, the baking of coffee beans is divided into several different degrees: 1, very shallow fried company; 2, shallow fried company; 3, shallow fried accompany; 4, shallow fried accompany; 5, medium fried accompany; 6, medium and deep fried accompany; 7, deep fried accompany; 8, very deep fried accompany.

Since a single coffee bean lacks the complex flavor necessary to make a delicious cup of coffee, the coffee beans sold on the market are mixed and packaged with three or seven different types of coffee beans. In general, those who have high attainments in coffee (that is, baristas) will artistically mix each kind of coffee beans according to their characteristics to create a flavor that is generally popular.

There are about 40 species of coffee plants, but the only coffee beans with real commercial value are "Arabica", "Robusta" and "Liberica (Liberia)". Arabica is currently the largest major variety of coffee beans, accounting for about 80% of the output, and its aroma and quality are excellent; Robusta is mostly used to make instant coffee because of its poor quality; Liberica is rarely mentioned because of its quality and low yield.

Here is a mention of "new and old" coffee beans. The "new beans" refer to the coffee raw beans harvested that year, the "old beans" refer to the coffee raw beans produced the year before, and the "old beans" refer to the raw beans harvested earlier. Only the new beans produced in that year are high-grade products, because the taste and aroma of new beans are relatively rich.

In addition to the three original species, each of them can be subdivided into more variety branches. Among them are Brazil Santos, Columbia Grand Class, Jamaica Blue Mountain, Hawaii Kona, Kenya coffee beans, Costa Rica Tara beads, Yega Chefe, Sumatra Manning, Papua New Guinea, Guatemala Antigua, Zambia coffee beans and other coffee beans classification.

It can be divided into different grades according to the elevation of the cultivated land. Generally speaking, the quality of highland beans is better than that of lowland beans, and the price is higher because of the increase in freight.

On the other hand, coffee powder thinks that it has a large area of contact with the air, which itself has a large degree of flavor loss, and it tastes less delicious than coffee and ripe beans.

When it comes to flavor, when you are shopping, you always want to find the kind of smell you expect. It must be difficult to express it verbally. After all, human beings have the poorest description of olfactory words. At this time, we need the help of coffee flavor wheel. This is a judgment from the American Special Coffee Association.
