When it comes to Kenya, the first thing that comes to mind for many fans is "Kenya AA", because it is the most exposed name both online and in stores. Moreover, anyone who knows a little bit about coffee beans knows that AA represents the level of quality.

The method of grading beans varies slightly from place to place.

For example, Brazil, the world's largest coffee producer, is labeled No.2--No.6; Guatemala according to the number of defective beans (defect beans) per 300g of raw beans and SHB--EPW according to the height of cultivation.

Kenya uses sieve size as the standard, combining density and shape to classify coffee. The reason for this is that the bigger the beans, the higher the content of oil that affects the flavor of coffee.

Kenyan coffee is rated as E-PB-AA-AB-C-TT-T-MH/ML.

Kenya E

The screen size is more than 18, which is called "Elephant Bean". Two face-to-face two seeds merged into one, suddenly mutated beans.
