Rainy and dry seasons must be well defined, and altitude must be between 1800-3600 feet. These conditions result in one growing season and one maturation season, usually in the coldest part of autumn.
Frequent rainfall causes almost continuous flowering, which results in two harvesting seasons.
The period of highest rainfall determines the main harvesting period, while the period of least rainfall determines the second harvest season. Artificial drying with mechanical dryers is performed on coffees grown in this type of culture since rainfall is too frequent for patio drying to occur. It is much more tolerant to warm conditions than Arabica coffee. Coffee Research Institute. All Rights Reserved.
