An introduction to the characteristics of the grindability of Yunnan Tieka Coffee

Bourbon: juxtaposed with Tibica as an ancient and excellent variety. Some botanists even believe that Bourbon is a variant of the early Tibika transplanted to Yemen, where the bean shape changed from a thin tip to a round body. It was not until 1715 that France transplanted Mocha round beans from Yemen to the island of Bourbon on the east coast of Africa, and it was not until 1715 that it received the name round bourbon. Bourbon, which spread to Brazil and Central and South America in 1727, is also round beans. In addition, the British transplant of Yemeni mocha to St. Helena Island in 1732 was also a round bean. interestingly, it did not pass through Bourbon Island, but it was named Green Top Bourbon. It can be seen that the industry thinks that all the world's bourbon beans come from Bourbon Island is a big misunderstanding. It is important to recognize that there are many round bourbon beans that spread directly from Yemen without passing through the island of bourbon. In 181○, some of the round beans on Bourbon Island mutated into pointed beans, also known as the "pointed body of bourbon." its caffeine content was only half that of ordinary coffee, and its output was low, weak, and extremely rare.

With the exception of Ethiopia, the origin of Arabica, the mutants or mixed-race varieties cultivated or found in Central and South America, India and East Africa are mainly Tibica and bourbon, and the genetic complexity is far lower than that of Ethiopia. this is the main reason for the weak physique and poor disease resistance of Arabica outside Ethiopia.

In addition, the biggest thing that bourbon and Tibica have in common is that shade trees must be "protected" to help block the sun. These two ancient varieties, such as unshaded trees, will not be conducive to growth and flavor development.
