How to know whether a new bean is good or bad? Cup test-professional criteria for testing beans

The quality of coffee beans is the most important thing for all coffee people. unroasted coffee beans enter the port from their place of origin. whether the quality of this batch of coffee beans is good, should not be imported in large quantities, and how much should be imported? this is the most urgent assessment that coffee traders want to make. You may wonder, in the face of so many kinds of coffee, how do they decide whether coffee is good or bad? That is the "cup test".

The "cup test" is a traditional method that has been used for more than 100 years. In a professional "cup test room," the life tie of all kinds of coffee is determined. They may be classified as second-or third-grade coffee beans, or they may be unused coffee, or they may be powerful products. In any case, everything is decided in this trial.

The whole "cup test" process goes something like this: a group of coffee experts or roasters first give birth to beans, then roast them immediately with a small amount of beans, and when the beans are cold, grind them into a generally coarse boiled water (97 degrees Celsius) into a short glass, then pour a certain amount of coffee powder into the cup. The standard quantity is 7.25 grams of coffee and 5 ounces of water. At this time, the coffee tested in different cups on the small table has already dissipated the aroma of the coffee, and the coffee powder in the cup has begun to bulge into hills and hills, so the expert picked up a spoon to open the coffee grounds, put his nose close to the mouth of the cup, sucked the breath of the coffee, sipped it with his mouth, felt the taste of the coffee, and then spit it out. They quickly spin the small table, drink cups of coffee, and divide them on the form. This is the "cup test".

The above is a very simple description of the "cup test", but the studies and qualifications involved in the whole process are actually complex and complicated, but if the owner has the interest of roasting coffee beans, the "cup test" is indeed the best way to understand the characteristics of all kinds of coffee.
