Grind size is one of the most difficult variables to master in pour-over coffee; it directly determines how efficiently water contacts the coffee grounds, and in turn affects the final flavor. Grind too fine, and the coffee easily turns bitter; grind too coarse, and the taste comes across as thin. Behind this are both the physical reasons of surface area and penetration distance, as well as the way the coffee bed obstructs the flow of water. Front Street Coffee tends to work backward from brew time to judge whether the grind setting is appropriate, and recommends using a No. 20 sieve to calibrate the passing rate. This article breaks down these principles one by one, and also explains the correct procedure for sieve calibration along with common misconceptions, to help you find that balance point within your own brewing system.
