Many coffee enthusiasts, before brewing pour-over coffee, hear experienced baristas emphasize the step of "seasoning the grinder."

The two serve different purposes and should not be confused. This article explains in detail why a small amount of beans from the same batch should be used to season the grinder before grinding coffee beans, how residual coffee powder and burr oils affect the flavor of the next cup, and why an air blower cannot replace bean seasoning. At the same time, Front Street Coffee will also offer recommendations on the amount of beans to use for seasoning, helping you present the true flavor of each bean in a purer way. [more…]

Therefore, the ideal situation is to grind the coffee beans right before brewing, to ensure you can taste the best flavor.

If you love brewing pour-over coffee at home, have you ever noticed that your brewed coffee tastes like it's mixed with other beans?

What's the difference between cleaning a hand grinder and an electric grinder? Can the burrs be washed with water?
