Why must coffee shops adjust their coffee grinder every day? Because the humidity of the coffee beans, storage time, and even subtle changes in air pressure, temperature, and humidity are all magnified under high-pressure extraction, directly affecting the quality of the final cup. Starting from the principles of grinding, this article explains in detail how the spacing of the burrs determines particle size and water flow rate, and teaches you to judge whether the grind is appropriate by observing the texture of the powder; it also provides a complete set of adjustment steps from traditional manual coffee grinders to electric coffee grinders, including the linked relationship between output volume and grind degree, and the optimal distance between the puck and the spout, and other practical parameters. No matter what equipment you use, only by mastering these adjustment principles can every cup of espresso consistently present the ideal flavor. [more…]

Grind size is the key variable that determines the success or failure of coffee extraction, and different brewing devices have significantly different requirements for particle diameter.
