Semi-automatic coffee machines are the most popular type of coffee machine for modern coffee lovers. Not only can people enjoy the rich aroma of coffee, but they can also adjust the grinding degree of coffee beans according to personal taste. And exploring the perfect coffee bean particle size has become the goal of many people's attention and pursuit.
First, we need to understand what grinding is. Simply put, grinding refers to the size of the whole coffee bean after it is cut into small particles. For semi-automatic coffee machines, the appropriate grinding can affect factors such as the contact area between water and coffee during the extraction process, the water flow rate, and the extracted solute content.
Secondly, there are several factors to consider when choosing the right bean particle size. If you want to make a strong and full-flavored espresso, finer (smaller) particles will be more suitable; if you prefer a light and light drip coffee, coarser (larger) particles will be more suitable. In addition, different coffee bean types and roasting degrees will also affect the grinding size.
Finally, there are some tips to pay attention to when adjusting the size of coffee beans. First, try and adjust according to your favorite taste. You can start with medium-fine grinding, and then fine-tune according to your personal taste. Secondly, remember to record the settings and results each time during the adjustment process, so that you can better understand what your favorite grinding degree is like and make it easier to replicate coffee with a similar taste in the future.
