Professional barista communication, please pay attention to coffee workshop (Weixin Official Accounts cafe_style)

This slogan comes from a white rice advertisement many years ago. At that time to buy rice, unlike today's supermarket to see, each package of equal weight, white grain. Rice shops are usually named after the number. Besides rice, he also sells oil, salt, fermented bean curd, and a colorful cat that catches mice for the boss. At that time, there was no preset weight for rice, and the price tag was still expressed in flower code. White rice was the boss's choice. Rusty cans of condensed milk were scooped out of the sacks one by one. Because of the different quality, foreign matter, chaff and wandering grain cattle need to be screened before entering the rice vat. Washing rice is an important hygienic step.

A green coffee bean is a fruit pit. As with other fruits, they may be damaged by insects, mildew or rot before they are air-dried in bags. Eating a bad apple will taste bad and affect your health; drinking a defective coffee will have the same effect.

Tonight, an old friend brought a packet of coffee to share with us.

"Look, this is coffee from a famous region. I saw the shop was cheap, so I bought it. Come and enjoy it!"

Cup Test Guard Boutique

The original intention of the cup test is to test, experience and evaluate coffee by a common set of standards for coffee farmers around the world. Unlike wine masters, the glass test is not "appreciation", but to protect the "fine"(100 points to get 80 points or more), and "commercial"(80 points or less) narrow difference between one point. Because the market prices of the two are so different, the results of the cup test are decisive for farmers 'livelihoods. To taste coffee, use the COE contest scoring paper. The difference between them is the flaw.

"Two cups. Why is it that this cup has a strong acidity, but it doesn't associate any fruit with it; that cup tastes not only bland, but also has an indescribable choking feeling afterwards?"

Each cup tastes less different

For coffee, you need to prepare five cups. If it is a boutique level, the taste of five cups generally does not differ much. Therefore, this bag will be deducted a lot of points.

"Quality of acid is more important than strength. This sharp acetic acid comes from ripe coffee fruit or sour bean; bland but choking, probably mixed with unripe beans (Quaker) and moulded beans."

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

Two days later, he angrily walked into our store and said,"The manager said that he had never defined coffee as a fine product with an 80-point standard, let alone recognized it!" I told him vinegar coffee was unacceptable, and he suggested I buy darker roasted beans next time.

Do I only mean? A slice of lettuce mixed with a plate is an analogy: "This vegetable is full of worms and the edges of the leaves are yellow." You said you didn't want to make a sandwich with this dish, so I suggested cooking it and serving it on a plate. Do you still want to eat it?"
