How to distinguish the grade of raw coffee beans? why do raw beans also have grades?

The name of the raw bean processing plant. For example, the long list of names of Guatemala, Antigua and Los Crop (Guatemala Antigua SHB- Finca Los Volcanes 12) tells us the following information:

Producing country: Guatemala (Guatemala)-Guatemala is a famous coffee producer in Central America.

Producing area: Antigua (Antigua)-this is the famous volcanic coffee producing area of the country.

Grading: extremely hard beans (SHB)-indicates that this coffee grows at an altitude of more than 4500 feet.

Production Manor: Finca Los Volcanes Manor-"Finca" is the Spanish word for "Estate", meaning farm.

Harvest year: 2012-the year is for roasters' reference, so the year is usually not marked on the label of roasted ripe beans on the market.

In the coffee beans sold in the market, in order to reduce the trouble and identification burden of consumers, they generally do not make such complicated labels. There may be great differences in the flavor of coffee beans in different small producing areas and different years. Professional roasters will taste the raw coffee beans of the same year in different producing areas every year, and adjust the way of roasting and blending, so that consumers can get coffee with stable flavor and slight difference.

However, although the coffee taste indication described above is a common practice of coffee roasters, because the domestic coffee market is in its infancy, consumers can not taste the differences in all kinds of beans, so the coffee beans sold on the market are mixed. There is often a phenomenon of inferior quality, so when consumers buy high-level coffee beans, they still need to keep their eyes open and carefully identify trustworthy businesses!

Central American coffee is graded on the basis of planting altitude, and coffee beans above 4500 feet above sea level are marked "SHB (Strictly Hard Bean)". "AA+" is the highest grade of Kenyan coffee, and only batches with particularly good flavor and few defects are allowed to be labeled "AA+". "AA" is the largest, "AB" is smaller, and "PB" is round beans. Colombia in South America uses the appearance size and defect rate of coffee beans as the grading standard, and "Supremo" represents the largest grain. It is worth noting that the appearance size of coffee beans has nothing to do with their flavor, but the higher the altitude, the better the taste of the coffee.

The name of the country is immediately followed by the marking of small producing areas. Take Ethiopia-Ethiopia (Ethiopia Yirgacheffe) as an example. Ethiopia's Ethiopia is the name of the coffee producing country, indicating that it is a "single coffee". Yega Xuefei Yirgacheffe is a long and narrow high-altitude producing area in the Sidamo producing area of Ethiopia (Sidamo). Different small producing areas mean different flavor characteristics. For example, places in southern Ethiopia near Somalia produce the famous
