Coffee beans would rather have some kind of basic knowledge of coffee.

Thousands of years ago, when Chen Sheng and Wu Guang rose up, he shouted: how dare a prince? Of course, it sounds very pleasant to us, who have long been used to the idea of equality for all, but if this sentence is put on the coffee beans, it is estimated that the beans will jump out and object: we all have to talk about our origins! In our view, they are all small black charcoal-like coffee beans, but according to Liang Chaoxiong, a veteran coffee expert, there are basically three species, arabica, robusta and liberica, although there are as many as 40 species of coffee plants. Among them, Lobusta is the most highway. it belongs to lowland coffee, with strong disease resistance and the highest yield, accounting for 60% to 70% of the output of coffee beans on the market. It can be found in Southeast Asia and West Africa. Its caffeine content is also high, instant coffee, canned coffee is the favorite.

Arabica is a typical "alpine flower", belonging to highland coffee, and most of the fine coffee comes from this category. Coffee such as Blue Mountain, which is an idol in the hearts of coffee fans, is also an Arabica species. It has appeared for the longest time in human history, and it is said that the coffee that was first introduced into the western world from the Arab world is Arabica coffee. It is the only coffee that all native species can drink directly, but it has a fatal point is its low disease resistance, how low is it? Sri Lanka was once a famous coffee-growing country, but all Arabica coffee growers in the country went home because of a coffee leaf rust, and they had no choice but to switch to black tea. It can be found in South America, Central America, Africa and parts of Asia.

When it comes to the least minority, Liberia is not as delicious as Arabica, and there is no large amount of money injected into planting, usually only for communication between experts or for research.
