The popularity of coffee was initially related to religion, but later became a threat to religious discipline. Coffee has become a subversive drink.

The planting of coffee

One of the characteristics of a coffee tree is its fruit, which can bear fruit several times a year, and another is that flowers and fruits coexist at different stages of ripening. If the trap is overripe, the beans will rot, and if not ripe enough, the beans will not ripen by themselves. The average yield of a tree is about 2 pounds a year.

The ideal growing environment for coffee trees is that the temperature is between 65 and 75 degrees Fahrenheit, the appropriate altitude and annual rainfall are between 40 and 120 inches, and the best soil is a mixture of decomposed volcanic soil, humic soil and permeable soil.
