[0002] Coffee is a beverage made from roasted coffee beans. It is one of the main beverages popular in the world, along with cocoa and tea. The coffee tree is an evergreen small tree belonging to the Rubiaceae family. The coffee we drink every day is made from coffee beans and various cooking utensils. Coffee beans refer to the kernels inside the fruit of the coffee tree, which are then roasted using appropriate methods. A standard cup of coffee should not taste bitter. A qualified barista will rigorously perform each step when making coffee, and the coffee served to the guests will have different degrees of sweetness, sourness, mellowness or cleanliness in taste.

[0003] The principle of coffee extraction. There are many coffee making equipment and methods, but the core extraction principle is the same. The core process of coffee extraction principle: 1. Grind the coffee beans to increase the surface area of ​​coffee in contact with water; 2. The coffee powder is fully immersed in the aqueous solution, and the coffee essence is hydrophilic and dissolved; 3. Separate the coffee solution and coffee grounds.

[0004] All modern coffee extractions involve two core processes: soaking and filtering. These processes fall into the realm of physics, and there is basically no chemical change in the process.
