Coffee trees generally blossom in 3-4 years, about 2-3 months a year. The appearance and smell of coffee trees are similar to those of jasmine flowers. After the flowers bloom, they produce small green fruits, which ripen and turn red into pickable ripe fruit after a few months, but not all the land located in this area can produce good coffee trees. The ideal planting conditions for coffee trees are: a warm climate with a temperature of 15-25 ℃, and a rainfall of 1500-2000 mm throughout the year, and the rainfall time should be consistent with the flowering cycle of the coffee tree. Of course, in addition to the coordination of seasons and rainfall, there should be fertile soil. The most suitable soil for growing coffee is a well-drained, fertile soil containing volcanic ash.

In general, the coffee sold in fast food restaurants mainly uses Robusta coffee beans as the material. Because it is made in Africa, most Africans drink robusta coffee. It has strong resistance to disease and high yield, accounting for less than 30% of the world's total coffee production. Robusta has low acidity, high caffeine content, brown color, thick fat and less flavor than Arabica, which can increase the taste and gelatinous taste of coffee.
