Analysis of Slow Pour-Over Coffee Flow Rate: What to Do When Coffee Won't Drain Properly?
Pour-over coffee, as a representative of drip extraction, can be seen as a process where water is first poured into coffee grounds, allowing the water to pass through the coffee layer and flow into the lower pot. With the assistance of an electronic scale, we can effectively control the pouring time. However, the total time for water to flow into the lower pot is affected by factors such as the grind size of the coffee grounds and the water absorption of the particles

Pour-Over Coffee Pre-Infusion Time Guide: Water Pouring, Coffee Grounds, and KALITA Dripper
The first water pour is the process of awakening coffee flavors, letting hot water flow gently from the pour-over kettle in a clockwise circular motion to moisten the coffee grounds surface. After a brief wait, the coffee grounds will expand, and within about 20 seconds, a few drops of coffee will flow from the pour-over cup. The duration of pre-infusion time determines the success of pour-over coffee, much like building a house requires a solid foundation—once the foundation is stable, half the work is done.
