Coffee Encyclopedia on the growth of Coffee trees

Coffee trees are evergreen shrubs or trees belonging to the Rubiaceae family; wild coffee trees can grow to 5 to 10 meters high, but coffee trees planted in the estate are cut to a height of less than 2 meters in order to increase the amount of unsightly fruit and facilitate harvesting. Coffee trees have opposite leaves that are long ovate and creamy, terminal branches that are long and sparsely branched, and flowers that are white and open at the base of petioles connecting branches. Mature coffee pulp is not beautiful outside the cherry, bright red, not beautiful meat sweet, containing a pair of seeds, that is, coffee beans (Coffee Beans).

Robusta beans Robusta coffee trees can grow on flat ground, have a strong resistance to disease and produce higher yields. Compared with Arabica beans, Robusta beans are round in shape, with a slightly swollen center on the cracked side and straight grooves reminiscent of soybeans, while Arabica beans are longer, with curved grooves, a bit like half a peanut.

Robusta beans generally taste more difficult, caffeine content is 2 to 3 times Arabica beans, cheap, mostly for the large coffee industry to produce instant coffee or low-cost products. Arabica coffee trees are suitable for growing on fertile slopes with good drainage at altitudes of about 1,000 to 2,000 meters. The weather for development is not too wet, but it still needs continuous rainy seasons and abundant rainfall.

Based on these characteristics, most of the parks suitable for Arabica coffee development are located in countries with high mountains between the Tropic of Cancer, which is also known as the Coffee Zone/Coffee belt.
