What is the ideal grind size for a semi-automatic coffee machine?

Semi-automatic coffee machines are a common type of household coffee machine that can provide high-quality coffee while maintaining a certain degree of manual operation. One of the key factors is the grind size. The ideal grind size is very important for semi-automatic coffee machines, which directly affects the flavor and taste extracted from the coffee beans.

First, the ideal grind size should be uniform and fine. This means that each powder particle is similar in size and there are not too many large particles. If the powder particles are not uniform or there are too many large particles, the water will flow through unevenly, and some areas will be extracted too quickly and others too slowly. This will not achieve the best concentration effect.

Secondly, it is also important to choose the right degree of fineness in the center. Generally speaking, using slightly finer beans in the center can better release aroma and flavor substances, and produce a more intense, full, balanced and smooth taste.

In addition, when adjusting the grinding degree, you also need to adjust it according to the type of coffee and the brewing method. Different types of coffee beans have different characteristics, such as Arabica and Robusta. And different brewing methods, such as espresso, American drip or French press, will also affect the ideal grinding degree.

Finally, when using a semi-automatic coffee machine, we should also pay attention to maintaining a certain degree of flexibility. Even if you have an ideal grinding setting, you may need to fine-tune it due to other factors (such as air humidity, freshness of beans, etc.). Therefore, you should often try and make appropriate adjustments according to your personal taste preferences during use.

In short, the ideal grind size of a semi-automatic coffee machine is uniform and fine, and should be adjusted reasonably according to the type of coffee and brewing method. It is very important to maintain flexibility in actual use and make fine adjustments according to personal taste preferences. Only in this way can you make a satisfying and high-quality cup of coffee.
