How to make coffee from coffee beans?
From the picking of the original coffee plantation to the peeling of the picked coffee beans; From cleaning or solar fermentation to screening and baking of raw coffee beans; From grinding to extraction, from pouring into the cup to sliding into the belly. Do you know how coffee beans are made into coffee? Come and have a look with me!
Production technology of coffee beans
A coffee tree can harvest 3-5 kilograms of fruit, and raw coffee beans account for 1/5 of the fruit quality. From fruit to raw coffee beans, it is really a time-consuming and laborious work.
Arabian species, Robusta species, Liberian species
Arabian coffee accounts for about two-thirds of the world's coffee production. Plants are not suitable for high temperature, low temperature and rainy environment. Coffee beans are oval and flat, with excellent quality and rich aroma.
Robusta coffee has a strong bitter taste, no sour taste, and the fragrance is not very good. Relatively speaking, mixed use is better than single use. It is often used to make frozen coffee, instant coffee and canned coffee. Suitable for planting in low-lying areas. Plants have the characteristics of strong disease resistance and fast growth.
Coffee grown in Liberia is of poor quality and low yield, and only exported to Europe.
Lentils and round beans
Mature red coffee fruit, as shown in the figure, has a multi-layer structure. The light green stone with a little blue in the middle is the coffee bean.
Generally, the core of coffee fruit is oval. When two stones face each other, lentils are formed; Sometimes stones grow alone to form round beans. The difference between these two kinds of beans is mainly in taste.
From harvest to delivery
After the fruit is harvested, the peel and pulp must be removed. Coffee beans are made by removing the endocarp and silver skin. There are two methods: drying (natural drying, no washing) and washing.
Dry, easy to operate. Spread the harvested fruit in a dry place and dry it in the sun for a week or two. You can hear the sound of la la la la when you turn, which means it's dry. Then use a sheller to remove the pulp, endocarp and silver skin of the dried fruit.
This method makes coffee beans have soft acidity and mild bitterness. Brazil, Ethiopia, Yemen and other places use this law. Disadvantages: vulnerable to the weather, there are many opportunities for inferior beans and foreign bodies to mix in. So be sure to choose carefully before delivery.
Water washing method: pour the harvested fruit into the sink to remove floating objects, move the fruit in the water into a pulp remover to peel off the peel and pulp, then put it back into the sink to remove floating objects and put it into the water. Fruit stone? Pouring into a fermentor, soaking for half a day or a day, removing gum on the surface of fermented beans, washing with water, sun drying or mechanical drying, and removing endocarp on a sheller to obtain commercial raw coffee beans.
Washed. Advantages: Coffee beans have good luster, less impurities and slightly better acidity. Colombia, Mexico, Guatemala and other countries have adopted this method. Coffee beans produced by water washing account for almost 70% of the total coffee bean production.
Sometimes improper treatment of fermentation time will produce fermentation smell and special sour taste; Good treatment can form the personalized aroma of coffee beans.
At this time, coffee beans can be transported to various places in sacks, or they can be put into special containers to cross the ocean.
How coffee beans become coffee?
Here are seven simple rules for making good coffee:
● Use freshly roasted coffee beans and store them for no more than one week, preferably half an hour ago. Just like participating in a competition, you need to warm up. What you need is a ready mood. Coffee beans are carefully roasted, Napoli style, with different ovens at different temperatures and humidity, and different temperatures at different stages; When the temperature reaches, it needs to be ground, and the brewed coffee is golden amber.
● It seems nothing to store coffee beans in a container that is protected from light, but the impact does make the most precious things change strongly inadvertently. Protect it and don't let it go bad inexplicably when it appreciates.
Freshly ground coffee beans need to be ground before brewing, but it is necessary to grasp the opportunity. Premature molding can only bring unnecessary waiting, and it is difficult to ensure that things will not deteriorate while waiting.
● Before use, put the tap water for a few seconds, then boil the water with fresh cold water just flowing from the tap, but the time should not be too long, and don't pour the boiling water on the coffee. Don't be careless in the process of making coffee and don't know how to treat beans well. Even the blue mountain coffee beans will turn sour.
● Use your favorite method-piston, dripper or any other method-to ensure that coffee has enough brewing time. No matter what method is used, even if the preliminary preparation is complete and perfect, it will take enough time and be in no hurry. Life, a little peaceful taste, is the most perfect.
When everything is ready, there is no need to wait. Cooling is a terrible thing, and the constant production and accumulation of tannic acid during cooling is enough to destroy carefully brewed coffee.
Remember to preheat the cup before pouring coffee. One is very hot and the other is very cold. It's easy to change cups when burned, but coffee tastes bad and it's difficult to recover. You know, the brewing process can be the same, but it is difficult to use raw beans.
Conclusion: Just buy a good coffee machine to make coffee. Every cup you drink will blossom and bear fruit after five years of growth. After complicated procedures such as harvesting and baking, and careful preparation by barista. The above is how I share coffee beans to make coffee. Do you remember?
