Pouring Technique
How you pour water is the most hands-on lever in the whole brew. The same coffee, grind, and ratio can yield a clean, sweet cup or a hollow, sour one depending purely on where you pour, how high from, how fast, and how steadily you control the kettle. This note covers the mechanics; how you sequence those pours is pulse vs continuous.
#The Four Pour Variables βοΈ
| Variable | Lever | Effect |
|---|---|---|
| Pattern | Center vs spiral | Evenness across the bed |
| Height | Close vs high | Agitation energy |
| Flow rate | Slow vs fast | Bed level & turbulence |
| Placement | Where on the bed | Avoiding the walls |
#Center vs Spiral Pours π―
A center pour keeps the stream in one spot. It is gentle and stirs the bed less β useful when you want low agitation or are working with delicate grounds. A spiral pour moves outward in concentric circles, then back to the center, distributing water across the whole bed for a more even saturation.
#Pour Height
Pour from low (a few centimeters above the bed) for a soft, calm entry; pour from high for a thin, energetic stream that drills into the grounds and adds turbulence. Height is your agitation dial: higher means more extraction energy, but also more risk of digging a crater. Most balanced recipes pour from a low-to-moderate height.
#Flow Rate and Kettle Control
A gooseneck kettle exists for exactly this β its narrow spout gives you a precise, controllable stream that an ordinary kettle cannot. Aim for a steady flow, typically 5 to 10 g per second for a single cup. Keep the scale running so you pour to a target weight, not a guess.
If your bed keeps craters or you taste harshness, lower your kettle and slow your flow. A gentle pour is the easiest fix for over-agitated brews.
#Maintaining Water Level
Many brewers keep the slurry level fairly constant during continuous pours, replacing water as it drains. Others let it draw down between pulses. Either works β what matters is consistency from brew to brew so you can dial in deliberately. Pour technique interacts with grind and dripper shape: a flat bed forgives sloppy pouring more than a steep cone.
