The long rainy season occurs from March to May, and the rainfall reaches 300-600 mm. The areas outside the double bee distribution rainfall area belong to the single bee distribution rainfall area, the rainfall time is from November to April, and the rainfall reaches 500-1000 mm.

"fresh" is the most important factor in buying Kilimanjaro coffee beans. There are several steps to judge whether the beans are fresh or not.

1. Grab a handful of coffee beans and feel whether they are solid beans with the palm of your hand.

2. Whether it is enough to smell the aroma close to the nose.

3. Put a bean into your mouth and bite it twice. There is a clear sound indicating that the bean is well preserved and not damp.

If you want to buy a single Kilimanjaro coffee bean, grab a handful in the palm of your hand, in addition to the above judgment, but also look at whether the color, grain size and shape of each bean are similar, so as not to buy mixed beans. If you buy mixed beans, it is normal to have different colors, grain sizes and shapes.

Tanzanian coffee is mostly washed. After picking, coffee farmers will send the coffee fruit to the nearest processing plant for processing. The treatment step of the water washing method is to screen and remove the impurities in the coffee fruit, then remove the coffee pulp and exocarp, and send it into the fermentation tank to remove the pectin layer on the inner pericarp by fermentation. clean and then dry. Coffee in Tanzania is graded in the same way as in Kenya, both according to the size of coffee beans. When screening, let the raw coffee beans pass through the screen with fixed size holes. The larger the number of the screen is, the larger the particles of the raw coffee beans are. The flat beans classified by size are mainly AA+, AA and AB. In addition, PB (peaBerry), which is widely produced in Kenya and Tanzania, also has a set of sieve size standards, which specifically classify the size of round beans.
