The influence of Coffee defects on Coffee quality

"fly sand and stone, fly nail and iron, vacuum packing to ensure freshness."

This slogan comes from the White Rice advertisement many years ago. At that time, I bought rice, unlike what supermarkets see now, with equal weight and white grains. Rice shops are usually named after "number". In addition to rice, it also sells oil, salt and fermented bean curd, and there is also a cat that catches mice for the boss. At that time, the rice had no default weight, and the price tag was still expressed in fancy code, and the white rice was taken by the boss. The rusty condensed milk jar was scooped out of the hemp bag. Because of the difference in quality, it is necessary to screen foreign bodies, husks and grain cattle wandering around before entering the rice tank. Washing rice is a very important sanitary step.

A raw coffee bean is a kernel. Like other fruits, they may be eaten, moldy or rotten by pests before they are dried into the bag. If you eat a bad apple, it will taste bad, and if it is heavy, it will affect your health; if you drink coffee with defects, the consequences will be the same.

Tonight, my old friend brought a bag of coffee to share with us.

"look, this bag is coffee from a famous producing area. I saw that the shop was very cheap, so I bought it. Come and have a test and enjoy it! "

Cup test guard boutique

The original intention of cup testing is to test, experience and evaluate coffee for coffee farmers around the world on the basis of a common set of standards. Unlike the wine chef, the cup test is not to "appreciate", but to protect the narrow gap between "boutique" (full score of 100 points for 80 or more) and "commercial" (less than 80 points). Because the market prices of the two are very different, the result of the cup test is decisive for the livelihood of farmers. To taste the coffee, use the score paper of the COE competition. The difference is precisely the flaw.

"I made two cups. Why does this cup have strong acidity, but do not associate it with any fruit? that cup is not only insipid in taste, but also has some indescribable choking feeling in the end. "

Each cup tastes little different.

For a cup of coffee, you need to prepare five cups. If it is a boutique, the taste of the five cups is generally not much different. As a result, this bag will be deducted a lot of points.

"the quality of acid is more important than strength. This sharp acetic acid is caused by ripe coffee fruit or excessive fermentation (sour bean); plain but choking, may be mixed with unripe beans (Quaker) and moldy beans (moulded bean). "

One defective bean is enough to affect the taste of the whole cup of coffee. What's more, long-term consumption of drinks infected by bacteria or fungi may be harmful to health. Therefore, to some extent, the cup tester is the health guardian of the public.

Two days later, he walked angrily into our store and said, "the manager said that he had never defined coffee as a boutique on the basis of 80 points, let alone recognized it!" I told him that vinegar-like coffee was not acceptable, so he suggested that I buy deeper-roasted beans next time. What do you think? "

What do I mean? An analogy is given to a piece of lettuce mixed with a plate: "this piece of vegetable is covered with worms, and the leaves have turned yellow." You said you didn't want to make sandwiches with this dish. I suggest fried it and put it on the plate. Do you still want to eat it? "
