1. Types of coffee beans

At present, there are more than 100 kinds of coffee in the world, of which two of the most common are Arabica and Robusta/Canephora. These two kinds of coffee are very different in taste, composition and growing conditions. We will compare the differences between them below.

Arabica (Arabica): expensive, supple taste, low caffeine composition, Arabica has a low caffeine content (0.9-1.2%), 60% more fat than Robusta, and twice as much sugar, so taken together, Arabica tastes sweet and soft, with a plum-like sour taste.

In addition, Arabica has lower chlorogenic acid (5.5-8%), and chlorogenic acid is not only antioxidant, but also an important component of resistance to pests, so Arabica is more vulnerable to insects and climate, generally planted at higher elevations, bearing less fruit and slower. The fruit is oval.

2. Coffee processing method

Several common treatment methods are: sun exposure, water washing, honey treatment and barrel fermentation, which is popular for more than one year. Sun: coffee beans have rich fruit aromas, sweet aftertaste and high mellowness. Washing: coffee beans have fruity or floral aromas, moderate acidity and low mellowness. Honey treatment: coffee beans have a sweeter aftertaste, delicate fruit aroma and high mellowness. Barrel fermentation: coffee beans, which are related to the corresponding aroma of wine, such as brandy, whisky, etc., with moderate alcohol and low acidity. The treatment method is related to the local natural conditions. if the local sunshine is abundant, there will be more water-deficient sun treatment methods, on the contrary, there will be more washing treatment methods.

3. The grade of coffee beans

The purpose of coffee bean grading is to provide a rough benchmark for trading. At present, there is no universal method for grading coffee beans. In fact, the name and basis of the classification is decided by each producing country. Identification criteria: 300g raw beans were selected and screened through metal sieves with different hole sizes (Screening). The basic unit is 1gamut 64 inches, called "mesh". The mesh used to screen coffee beans is between 8muri 20 mesh, that is, 8Uniq64. The smaller the number is, the larger the hole is. Usually less than 14 goals, there is no chance of becoming a boutique. In the process of screening, of course, there will be fish out of the net, and the allowable value of error depends on the standard adopted.
