The difference between hand-ground Coffee and Machine Coffee introduction to the types and characteristics of hand-ground coffee beans

What's the difference between hand-ground coffee and machine coffee? We take the most common espresso machine outside as the representative of the machine coffee. Hand-ground coffee is generally used to make hand-brewed coffee. Let's compare the difference between the two. The coffee produced by the Italian espresso machine is a very full-bodied cup of coffee with a mellow taste and rich oil. The espresso machine grinds the beans into a very fine coffee powder and then fills it in the handle. Using great pressure for extraction, the water quickly passes through the tight layer of coffee powder, bringing out the soluble matter in the coffee.

Hand-brewed coffee is brewed with a hand filter cup, and its coffee powder will be much thicker than Italian coffee. If the coffee powder is too fine, it will block the exit, the coffee liquid will not flow out, and it will be particularly bitter in the mouth. The grinding thickness of hand-brewed coffee is about white granulated sugar. The flavor of hand-brewed coffee is reflected according to the flavor of coffee bean producing areas. For example, African coffee beans are more sour and have obvious floral fragrance. Asian coffee beans are rich in herbs, chocolate flavor, mellow thickness and bitterness, while American coffee beans are more balanced. Somewhere in between.
