Many people think that coffee is a black powder in a jar, but they forget that coffee is actually a tree with seasonal and periodic fruits. It needs a series of complex artificial polishing to become a warm drink with a strong fragrance. The perfect transformation of a cup of coffee starts with coffee beans. Now let's talk about coffee beans.

Growth Of Coffee Beans

The coffee tree is a shrub with oval leaves, and the coffee bean is the seed part of the coffee tree fruit. As a crop, coffee beans are cultivated in more than 70 countries around the world. Good coffee beans need specific conditions. For example, Arabica coffee planting needs to meet three conditions: the temperature is appropriate and stable, the latitude is within 10 degrees north and south of the equator, and the altitude is between 915 and 1830 meters.

Today, a coffee shop is a cozy place. Not only do they serve delicious coffee and coffee drinks, but they also have sofas for you to sip and relax on. So how did the coffee shop come about? Do you know the origin and history of the coffee shop?

In addition to the specific geographical environment, climate, and temperature, coffee beans also need the patient care of professional planting workers and regular fertilization and pruning to become a good coffee bean to be brewed. Generally speaking, coffee trees begin to bear fruit and grow coffee only 3 to 4 years after planting. In this process, planting workers are required to regularly fertilize and prune coffee trees. Only when the coffee is ripe can it be picked. The immature green coffee, half ripe or over ripe Brown fruits need to be removed manually. The strict growth environment requirements and high labor costs lead to the high price of high-quality coffee beans.

Perhaps you think that after ripe coffee is picked, a cup of rich and good coffee is not far away. But in fact, there is still a lot to be done.

Quality Of Coffee Beans

The quality of coffee beans is reflected in many aspects. When selecting coffee beans, it is necessary to understand the size, density, moisture content, and other factors of coffee. Secondly, we need to have a deeper understanding of the processing methods of raw coffee beans, pay attention to some necessary details in the processing of coffee beans, and how the coffee beans are different under different processing methods. After knowing the physical characteristics such as the treatment method of coffee beans before baking, it is also necessary to check whether there are defective beans, such as some fermented beans, dead beans, black beans, moth beans, incomplete beans, etc., which will affect the flavor of the coffee.

When actually selecting coffee beans, we can start with the aroma, purity, skin, freshness, and other aspects of raw coffee beans:

Aroma

Healthy coffee beans should smell like herbs, fruits, flowers, and even wood. If the coffee beans have lost their fragrance or smell old, it means that the coffee beans are no longer fresh. Freshly fried coffee beans are not suitable for immediate drinking. They should be stored for a week to fully release the air in the beans before grinding and drinking. Generally speaking, the best time to drink coffee is after a week of stir frying. At this time, the coffee is the freshest and the performance of flavor and taste is the best.

Purity

Grab a handful of single coffee beans (i.e. a single variety of coffee beans) and weigh about dozens of beans to see whether the color of each single bean is consistent and whether the particle size and shape are similar. However, if it is a comprehensive bean (i.e. coffee beans mixed with multiple varieties), it is normal that they are different in size and color.

Epidermis

The epidermis of normal fresh coffee beans is light green without obvious spots. If the surface of the coffee bean is black, its interior may have been rotten; If the skin is yellow, it may be moldy, and the coffee will have a sour taste; If the surface of the coffee bean is white, it is very likely that there are insects inside it.

Fresh

Fresh coffee beans are fresh and crisp. When they are cracked, there is a fragrance floating out. You can take a bean and bite it twice. A crisp sound means that the beans are well preserved without moisture.

Defect Classification:

• High quality coffee beans: with neat shape and bright color, they are roasted by single frying. After boiling, they are mellow and full of stamina.
• Poor quality coffee beans: different shapes, incomplete individuals, light fragrance after boiling, not enough glycol.

After the quality of coffee beans is determined, they are ready to enter the baking stage. It should be noted that when baking coffee beans, try not to bake more than 3 mixed coffee beans at the same time, otherwise it will be difficult to control the baking curve because the density difference of coffee beans is too large.

5. Civet Coffee

Cat excrement coffee is the rarest, most unique, and most expensive coffee in the world. It is produced in Sumatra. After the local people feed the civet with coffee fruit, they extract the coffee beans from the cat feces. Due to the special fermentation of civet intestines, the flavor of coffee beans has become more unique, especially thick and mellow. However, this kind of civet is originally an omnivore. In order to pursue interests, many unscrupulous businesses catch civets and only feed them coffee nuts, which damages the intestines and stomach of civets. The life span of civets is not long. Moreover, the coffee beans fed artificially have not been screened and the quality is uneven. Therefore, coffee with the word "cat excrement" may not be good coffee, so it should be carefully selected.

6. Geisha Coffee

Guixia coffee is one of the most popular bean varieties and a special variety of Ethiopian heirloom coffee. This kind of coffee was first discovered in Guixia. It is very precious because of its low yield. The flavor of this coffee is mainly fruity and has an aroma similar to oolong tea. It tastes like drinking herbal tea.

7. Guatemala

Antigua coffee is produced on Antigua island. Because it is planted on the hillside in the hinterland of the volcano, the beans will contain nitrogen. After baking, they will have the smell of charcoal burning or smoke. However, the expression of this flavor also has a great relationship with baking depth. For example, it is difficult to show these flavors in the case of medium baking.

8. Kona, Hawaii

Some people praised Blue Mountain as the king of coffee and Kona as the queen of coffee. The reason why some people praise Kona coffee in Hawaii is probably related to the special terrain conditions for its growth. Kona coffee in Hawaii grows in island terrain and volcanic soil areas. For this reason, the coffee in Hawaii has a very special taste, not too strong, with a mellow wine aroma and acid. However, due to the small output and high production cost, the price is relatively expensive.
