Coffee cup testing standard and process | Japanese SCAJ coffee cup testing process and scoring focus

"Cup test" can stably control the flavor of each cup of coffee.

The cup test record is closer to the practice of "professionals".

The goal of taste control ​​ is to feel good yourself? Match the preferences of the target customers in the store? Or is it to focus on popular taste? In fact, you just have to decide the direction of the taste according to your own ideas, and try to get close to that taste.

Before deciding on the taste, constantly changing the conditions for repeated extraction can also hone your skills and train your sense of taste. At this stage, the most important thing is to leave a cup test record.

When drinking coffee by hand, if you only feel "a little sour", "astringent" and so on, your coffee extraction technology will not improve.

The cup test is the last checkpoint for the taste of coffee. According to the taste of the cup test, review the advantages and disadvantages of extraction under each condition (what you care about), and objectively test which elements of the next extraction should be changed in order to get closer and closer to your ideal taste.

There are several ways to measure the cup. the following is the Japanese Fine Coffee Association (SCAJ) cup test without using extraction tools, and the Baja Cafe Cup test using extraction tools to compare the actual extract.
