The relationship between roasting degree and extraction rate: the lighter the roasted coffee bean fiber is, the harder it is to dissolve the flavor, so it is necessary to brew at a higher temperature, a longer time or a finer grinding degree to avoid insufficient extraction. On the contrary, deep-baked beans should be brewed at a lower water temperature, a shorter time or a coarser grinding degree to avoid excessive extraction. Understand and apply what you learn.

The relationship between roasting degree and extraction rate when brewing coffee: the shallower the roasted coffee bean is, the harder the fiber is, and the harder it is to dissolve the flavor, so it is necessary to brew it with higher water temperature, longer time or finer grinding degree, so as to avoid insufficient extraction. On the contrary, deep-baked beans should be brewed in a lower water temperature, brewed in a shorter time or coarsely grinded, so as to avoid excessive extraction. Understand and put what you have learned into practice.
