Following Cafe (official account vdailycom of Wechat) found that Beautiful Cafe opened a small shop of its own. In fact, Robusta also falls into many categories and can't generalize or pursue price blindly. Among the big coffee countries, Robusta is a major producer of Vietnam, Brazil, Indonesia, India and so on. Like Arabica, Robusta in each country has a corresponding hierarchy.

In fact, Robusta is also divided into many categories, can not be generalized or blindly pursue the price. Among the big coffee countries, Robusta's major producers are Vietnam, Brazil, Indonesia, India and so on. Like Arabica, Robusta in each country has a corresponding hierarchy. According to different grades, we can see the general quality standard of raw beans.

Today is a question rarely discussed in the coffee world: how is Robusta coffee graded?

Brazil

In Brazil, Robusta's output is called Conillon. Geographically, the main coffee producing areas of Robusta are:

Espirito Santo, Esp í rito Santo

Mato Grosso, Mato Grosso State

-South Bahia, Bahia (Sul da Bahia)

Rond ô nia, Londonia

Robusta is usually graded according to particle size:

4 take 5 (screen 14 to 17 +)

5Accord 6 (as of screen 13)

6 (as of screen 12)

Classify according to treatment

Indonesia's Robusta is famous all over the world. The main treatment methods are dry treatment and wet treatment.

Dry treatment usually refers to washing with hot water after insolation. This kind of coffee beans is called A.P. (After Polished).

When Robusta is treated in the traditional way, it is called wet treatment. It is usually determined by the quality of the processing:

EK1 (Dutch: & # 39 world erst Kwaliteit' = first quality) High quality

G.B. (Dutch: & # 39 × Gewone Bereiding' = simple preparation) minimalist standard

O.I.B. (Dutch: & # 39 th Oost Indische Bereiding' = East-Indian preparation) East Indian standard

W.I.B. (Dutch: & # 39 th West Indische Bereiding' = West-Indian preparation) West Indian standard

W.I.B. It is the highest standard and the most common one.

At present, the new classification method uses defect rate for classification. In practice, however, the new and old standards are actually used at the same time.

Viet Nam

Vietnam Robbins Tadou is divided into only three levels: G1Magol G2 and G3. It is mainly divided according to defects.

For each grade, the official criteria for raw bean size are as follows:

Grade 1: > 7mm

Grade 2: > 6-7 mm

Grade 3: > 5mm

In practical application, the widely used sieve mesh data for particle measurement will also be provided.

G1 Vietnam Robusta is often labeled as 16 mesh (90% 16 mesh or more) or 18 mesh (90% 18 mesh or more).

In order to make it easier to compare with Indonesian standards, the classification criteria are as follows (released in November 2001):
