What is grinding?

Before extracting coffee, we need to grind the boiled coffee beans. The purpose of doing this is simple, that is, to extract effective components from coffee beans. After coffee grinding, the extraction area will increase exponentially; It is easy to dissolve most of the flavor substances in coffee after water injection. Grinding degree The size of coffee grinding particles has a great influence on the dissolution mode and extraction speed. Therefore, we should be based on brewing equipment and extraction.

Select the appropriate "grinding granularity".

Simply put, the longer it takes to brew coffee, the coarser the coffee powder particles that need to be ground; On the contrary, if coffee is to be extracted in a short time, the particles of ground coffee powder will be finer.
