Aesthetically, pour-over kettles are typically characterized by a long, slender spout—usually 10-15 centimeters long, with a pointed “swan’s beak” or slightly flared “slanted” end. This design minimizes water flow dispersion, allowing the water to fall precisely onto the coffee grounds on the filter paper like a fine thread. Whether using circular extraction or targeted pouring, it prevents the water from scattering the coffee grounds and causing uneven extraction due to a coarse flow. Some high-end pour-over kettles also feature “flow channels” on the inside of the spout to further optimize water flow stability, allowing even beginners to easily control the water flow speed.
