The definition of coffee basic knowledge and fine coffee beans

1. Boutique coffee beans must be high-quality beans with flawless beans. It should have an outstanding flavor, not "no bad taste", but "taste particularly good".

two。 Boutique coffee beans must be excellent varieties, such as the original bourbon species, mocha species and Tippica species. The coffee beans produced by these trees have unique aroma and flavor, which is far from that of other tree species, but the relative yield is low. in recent years, in order to pursue the ability of disease and insect resistance and increase the yield, there have been many improved tree species, such as Kenya to promote a large number of high-yield rurial11 species, but the taste and quality are greatly reduced. Of course, you can't call it "boutique coffee".

3. The growth environment of boutique coffee beans also has higher requirements. Generally grow at an altitude of 1500 meters or even more than 2000 meters above sea level, with appropriate precipitation, sunshine, temperature and soil conditions. Some world-famous coffee beans also have a special geographical environment, such as the alpine clouds in the Blue Mountains, the free shade provided by Kona's afternoon "Flying Cloud", and the volcanic ash soil in Antigua, which provide conditions for the growth of boutique coffee.

4. The best way to harvest high-quality coffee beans is to harvest them manually. That is, only mature coffee fruits are picked to prevent coffee fruits with inconsistent maturity from being picked at the same time. Because those unripe and overripe fruits will affect the balance and stability of coffee taste, boutique coffee needs to be picked frequently and carefully during harvest.

5. High-quality coffee beans are refined by water treatment. The coffee beans with less impurities can be obtained by the water washing method, but if the water quality and time are not properly controlled during the fermentation process, the coffee beans will easily be infected with the sour taste of excessive fermentation. and dry beans also need to pay attention to timely re-inspection to prevent coffee beans from being contaminated by wet ground and sundries. Processed beans should be dried in time, and the drying should also have a certain degree. Generally, the moisture content of processed beans is 11% 13%. Insufficient drying can easily make beans moldy, and excessive drying can easily affect the flavor of beans.

6. Boutique coffee has a strict grading system. In general, raw beans are preserved as "parchment coffee beans" in the form of endocarp after processing, and the endocarp is removed before export. Go through a strict grading process to ensure the uniformity of quality. And its preservation and transportation in the process of protection is very important, such as temperature and humidity control, ventilation control, avoid odor adsorption and so on, if these do not do well, then no matter how high-grade beans will no longer become fine.
