What are the varieties of coffee beans?

The tree species of coffee determine the taste of coffee.

Coffee is mainly composed of two original species, Coffee Arabica and Coffee Robusta, each of which can be subdivided into more branches. Common coffee varieties Varietals:

Bourbon Bobang (the second species mutated from Typica is the closest to the original species with Typica at present. It was found in Reunion (formerly Bourbon) near Madagascar. It has the same high-quality taste as Typica, like the sour taste of red wine, and the aftertaste is sweet. We can tell from the leaves and bean appearance of coffee trees that Typica and Bourbon,Bourbon have broad leaves, while strong coffee cherries are smaller and denser, so the appearance of beans is smaller and more round than Typica. In Kenya and Tanzania, new artificial varieties "SL28" and "SL34" were produced by artificial mixing of Bourbon progeny, which is famous for its good flavor. Although the seed setting amount of Bourbon is higher than that of Typica, the harvest time is also 2 years, which can be regarded as a variety with low yield. )

Catimor Katim (Timor and Caturra hybrid). Was found in Portugal in 1959. The palate is obvious and easy to distinguish, bitter acid with a bit of astringency, and the finish is often salty. It is a high-yield variety with high planting density and strong resistance to leaf rust. )

Timor Timm, a hybrid of Arabica and Robusta found in East Timor, is closer to Arabica because its chromosomes are 44 in Arabica rather than 22 in Robusta. Tim has a low sour taste and lacks characteristics. )

Catuai Kadu loves the coffee variety of Caturra Kaddura and Mondu Novo New World. The tree height of Caturra is shorter than that of Mundo novo, and the improved height is more convenient to harvest after mixing. The sweetness performance is similar to that of Cattura, and there is a great correlation between fertilization techniques. Planting density is high, proper fertilization can have high production capacity, trees are resistant to wind and rain, and the harvest period is only 1 year, but the disadvantage is that the life span is only 10 years. )

Caturra Kaddura (mutant of Bourbon). It was first found in Brazil and began to be planted for commercial use in Minas Gerais, Brazil in 1937. The taste is sour with lemon or citrus taste, but it is not as sweet as Typica and Bourbon in sweetness, because the sweetness of Caturra depends on the number and dosage of fertilizer applied by growers, so it has high production capacity, but continuous fertilization and pruning is necessary to maintain production capacity, so the trees are short and branched. Although the production capacity has increased, the output is still limited because of the two-year harvest period and the high cost of care.
