The characteristics of coffee beans as the standard for judging high-quality coffee beans

At present, there is no clear judgment standard of fine coffee in the international community. Here, we will briefly explain the standards of the American Fine Coffee Association and the basic standards of coffee producing countries.

American Fine Coffee Association Standard:

1. Whether it has rich dry aroma (Fragrance). The so-called dry aroma refers to the aroma of roasted or ground coffee.

two。 Whether it has rich wet aroma (Aroma). Wet aroma refers to the aroma of coffee extract.

3. Whether it has rich acidity (Acidity). It refers to the sour taste of coffee, the combination of rich sour taste and sugar can increase the sweet taste of coffee liquid.

4. Whether it has rich alcohol thickness (Body). It refers to the concentration and weight of the coffee liquid.

5. Whether it has rich afterrhyme (Aftertaste). It refers to the afterrhyme of coffee, which is evaluated according to the flavor after drinking or spitting.

6. Whether it has rich taste (Flavor). Refers to the taste, the upper palate to feel the aroma and taste of coffee, to understand the taste of coffee.

7. Whether the taste is balanced or not. Refers to the degree of balance and combination between the various flavors of coffee.

Evaluation criteria for producing countries:

1. A variety of fine coffee. It is better to use Arabica inherent variety Tibica or bourbon variety.

two。 Is the altitude, topography, climate, soil and refinement of the cultivated land or farm clear? Generally speaking, the coffee with high altitude is of higher quality, and the fertile volcanic soil is the best.

3. The harvesting method and refining method are adopted. Generally speaking, it is better to adopt manual harvesting method and water washing refining method.

Characteristics of boutique 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 are 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.

Boutique coffee-drinking coffee:

1. Fine coffee is made from boutique coffee beans. If the beans that make coffee are not boutique coffee beans, the coffee liquid produced cannot be called fine coffee.

two。 Boutique coffee is fresh coffee. Whether it's food or drink, of course, the fresh the better, and so is boutique coffee. High-quality coffee should keep the coffee beans fresh before making, including the preservation of baked beans, and grind the coffee beans into powder before making, which is also to retain its original and best flavor. The way of making hand-brewed coffee is such a way to make high-quality coffee, and it is also one of the coffee-making methods that can best retain the original flavor of coffee.

3. Boutique coffee is good coffee and is harmless to health. Different from coffee made with low-quality coffee beans, high-quality coffee uses high-quality coffee beans and freshly made coffee, which is harmless to health, and drinking in moderation is beneficial to the body and mind.

4. Boutique coffee has a rich and beautiful taste. Even if the coffee made of boutique coffee beans is not all fine coffee, it depends on whether it gives full play to the characteristics of coffee beans, whether it has a good taste, if not, it can not be called boutique coffee.
