What are the coffee trees in China?

Robasta coffee trees are native to Madagascar in central and western Africa and Indonesia in Asia, and their production accounts for about 20% to 30% of the world's production. Robasta coffee tree is suitable for planting in lowlands below 500 meters above sea level. It has strong adaptability to the environment. It can resist harsh climate, resist pests and diseases. It does not need too much artificial care when preparing soil, weeding and pruning. It can grow freely in the wild. It is an easy to cultivate coffee tree.

However, the finished product tastes bitter than Arabica, the caffeine content is also relatively high, and the quality is also inferior, so most of them are used to make instant coffee. Because it is mainly grown in Africa, most Africans drink robasta coffee.

Bourbon (Bourbon): tied with Tibica as an ancient fine variety. Some botanists even believe that Boben is a variant of the early Tibica transplanted to Yemen, and the bean shape changes from thin and pointed to round. It wasn't until 1715 that the French transplanted the Yemeni mocha round bean to the island of Bourbon on the east coast of Africa, which began to receive attention and the name round bourbon. Bourbon, which spread to Brazil and Central and South America in 1727, is also a round bean. In addition, in 1732 Britain transplanted Yemeni mocha to St. Helena Island, which is also a round bean. Interestingly, it did not pass through Bourbon Island, but was named Green Top Bourbon. Therefore, it is a big misunderstanding in the industry that all Bourbon beans in the world come from Bourbon Island. It is important to recognize the fact that there are many round-bodied bourbon beans that travel directly from Yemen without passing through Bourbon Island. In 1810, some of the round beans on Bourbon Island mutated into pointed beans, also known as "Bourbon pointed beans," whose caffeine content is only half that of ordinary coffee. The yield is low and the constitution is weak. It is extremely rare.

In addition to Ethiopia, the origin of Arabica, the mutant species or hybrid varieties cultivated or discovered in Central and South America, India and East Africa at present are mainly Tibica and Boben, and the gene complexity is far less than Ethiopia, which is the main reason why Arabica outside Ethiopia is weak and disease resistant.

In addition, the biggest common ground between Bourbon and Tibica is that they must have shade trees to help block the sun. These two ancient varieties, such as trees without shade, will adversely grow and develop flavor
