Coffee beans, coffee beans, coffee beans.
Coffee beans also "would rather have guts" when Chen Sheng and Wu Guang rose up thousands of years ago, 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. Highland coffee is superior to others in the three major coffee beans, players are after Arabica beans. This is because highland coffee is better than lowland coffee. Therefore, when commenting on the quality of coffee, the height of the origin is often included in the evaluation criteria. The higher the altitude and the lower the relative temperature, the coffee fruit can ripen slowly, so the fully ripe beans have good expansibility and are easy to bake. In the coffee producing countries in Central and South America, the quality of coffee beans is basically evaluated only by the altitude of the place of origin. As for boutique coffee, it is all highland coffee. Of course, if you play more professionally and profoundly, you will probably see whether the coffee has organic certification or not. Players generally agree that: American USBA certification, rainforest certification, fair trade certification. Giving coffee beans a second life roasting is equivalent to giving coffee beans a finishing touch. The flavor of the coffee bean itself is latent, and only moderate baking can attract its amorous feelings, just as dry wood needs fire.
In the eyes of experts, 80% of the factors that determine the taste of coffee come from raw beans and 20% depend on roasting. Baking is divided into deep, moderate and shallow three kinds of baking, these three baking methods themselves are not high or low, or the coffee beans themselves are suitable for what kind of baking method, the key lies in the baking method. If the technique is wrong, even the best beans will be scrapped. The most difficult thing about baking coffee is the best time to stop, which depends on how the roaster captures the characteristics of coffee beans. This should be judged by experience and pay attention to the changes in temperature, color, sound, aroma, shape and luster of beans.
All coffee tastes bitter and sour. Generally speaking, the lighter the degree of roasting, the stronger the sour taste of coffee. The deeper the baking degree, the stronger the bitterness. Deep roasting is suitable for coffee with strong sour taste. Light roasting is suitable for bitter coffee, which can release the sour taste, ease the excessive bitterness and balance the taste. However, coffee has an expiration date, no matter how superb the roasting method is, drink it up within two weeks after roasting, otherwise the flavor will be greatly reduced. After the extraction essence of the decisive game has gone through the correct picking, production and baking, it comes to the last two gates of import, grinding and extraction. The two processes complement each other. The thickness of the grinding determines the way in which coffee is extracted. Generally speaking, fine powder is the easiest to extract the essence, so it takes the shortest time, which is extracted immediately after being washed quickly with water of 90 degrees Celsius, using an Italian machine and a mocha kettle.
For moderate grinding, it is usually drunk by the family. Preheat coffee cups and coffee pots to make the coffee more fragrant. The water temperature is generally 85 to 90 degrees Celsius, mainly hand flushing pots, dripping pots and siphon pots. As for the coarse powder, it should be on the French kettle, which takes the longest extraction time, and the water temperature is also between 85 and 90 degrees Celsius. The standard of good coffee there are a lot of professional terms used to judge coffee, which can be comparable to red wine, in fact, all of them can be ignored, their own tongue is the first judgment. Mr. Liang said that if the coffee is really good, it is actually very simple: it tastes comfortable, clean, odorless, pure aroma, and the most important thing is that the coffee beans should be fresh. If it had been put on for a year and a half, Xi Shi would have become a bell without beauty.

The coffee tree is an evergreen tree with small white flowers and green fruit that does not turn red until it is ripe. A normal coffee tree can usually grow to a height of 5 to 10 meters, but bean farmers often prune it to less than 2 meters for harvest convenience. After flowering, there are many dark green oval fruits, and the mature fruits change from dark green to bright red, due to the color and cherry.
