When buying coffee beans, in addition to the name of the coffee origin in the package or in the introduction, sometimes you will see the English and numbers, G1, G2, G3, AA, PB, SHB, SHG, HB and so on. Have you ever wondered what these English or numbers stand for? What's the difference between them?

In order to distinguish between good quality coffee beans and poor quality coffee beans, we have to grade the coffee.

Coffee grading is usually carried out according to defect rate, bean size, altitude, raw bean density, treatment standards, etc., but because each country's historical background, trade interests, climate, topography and other factors are different, we cannot use the same standard to calculate defects, or simply to compare heroes in terms of altitude, nor can we compare one country with another. These are all mistakes rather than objective direct comparisons.

Therefore, in more cases, it is a combination of a variety of standards for description, and in order to really understand these English and figures, we have to understand the classification and classification of coffee.

Classification and Classification of Coffee

In different countries, there will be their own accustomed way of grading. But basically, the most commonly used grading criteria are as follows:

1. Differences in the appearance of raw beans, such as size, shape, defect ratio.

two。 The environment in which raw beans grow and their effects, such as altitude and hardness.

3. After baking, it is judged by the quality of the cup.

As a result, coffee beans are graded according to some key points before they are processed for export:

① according to the proportion of defective beans

② by legume size

③ altitude and hardness

Quality test by ④ cup

Proportion of defective beans in ①

The less the proportion of defective beans, the higher the grade of beans, generally speaking, the producing area and the store will pick beans according to the condition of the beans. (voice of riddle: picking out defective beans is a very time-consuming and time-consuming thing.)

For example, Ethiopia's raw beans are G1~G5, G1 and G2 are washing grades, G3 and G4 are sun grades, and general commercial beans are G4. (in recent years, the preferred grades of many Ethiopian sun beans are also marked with G1 and G2. )

Jiayushan Mantenin grade is G1, natural shade planted high-quality Arabica beans, washing treatment.

Classification according to defect rate

American standard USP US preparation, European standard EP Euro preparation, extreme standard GP Gourmet preparation many countries have USP, EP and GP standards, USP\ EP is relatively more common. European and American standards are based on the specific requirements for the defects or items of raw beans, and sometimes there are other standards among them, which are not detailed because different national standards are different. Generally speaking, the EP standard is higher than the USP standard.

The editor, who is picking beans, said: "trash, come forward!"

② by legume size

That is, the length and width of the bean body (size), Colombia to "bean size is beauty" as the purpose, classification to the unit, more than 18 mesh (about 0.7cm) for Supremo, the following is Excelso. (item represents the diameter of the coffee bean, one item is 1x64 inch, 1 inch = 25.4mm)

Kenya's grading is based mainly on the size of beans, supplemented by cup quality and bean weight. So we often hear of Kenya AA, the highest quality grade is AA PLUS (AA+), followed by AA and AB (1516 orders, accounting for the majority of production). Wait. In addition, there is PB, which means Peaberry, which is classified by appearance.

A sieve used to determine the size of beans.

Columbia coffee beans grade Excelso, bright and balanced, thick taste with nutty and citrus aromas, naturally shaded high-quality Arabica beans, washed.

③ altitude and hardness

A producing country in Central and South America except Brazil and Colombia. For example:

Grade

Altitude

Mark

one

1350 to 1500 meters

SHB (Strictly Hard Bean) extremely hard bean

two

1200mm 1350m

HB (Hard Bean) hard bean

It is also divided into SHG (Strictly High Grown), SG (High Grown) and SC (Central Standard) according to altitude. Basically, the higher the altitude of coffee trees, the harder the coffee beans will be. this is because low temperature, short sunshine, high humidity and other factors will make coffee grow more slowly, grow fruits with higher density, and the flavor of coffee beans, such as acidity and sweetness, will be more saturated. In short, the altitude has a great influence on the quality of coffee beans.

Honduras coffee beans grade SHG (Strictly High Grown), balanced and soft flavor, melodious flowers, natural shade of high-quality Arabica beans, washing treatment.

Quality test by ④ cup

Although Brazil is one of the largest coffee producing countries in the world, among the coffee producing countries in Central and South America, Brazil's production altitude is on the low side, and its landform is flat, less shaded trees, and lack of micro-climate, so the coffee beans produced are soft, commonly known as soft beans, and taste smoother than other producing areas. So Brazil uses five grades to rate it:

1. Strictly Soft is extremely meek.

2. Soft compliant

3. Softish is a little softer.

4. Hardish is not catchy.

5. Rioy smells of iodine choking.

Smart Brazilians use taste for grading. The Brazilian Coffee Excellence Competition, Cup of Excellence, which has been held since 1999, uses the mild and smooth low acidity, mellow thickness and sweetness of Brazilian coffee, as well as the overall presentation of nutty and cocoa flavors, as the basis for coffee evaluation. "the sweetness, purity and smooth finish of the entrance" has become a representative feature of Brazilian high-quality coffee. This flavor also explains why Brazilian beans often play an indispensable role in special bean recipes.

In short, grading is an important consideration when we choose coffee beans; of course, raw coffee beans must be well preserved so that coffee farmers in the producing areas do not waste their hard work in planting and screening, and finally go through changes in roasting and brewing that vary from person to person. there will be millions of changes in the taste of coffee.
