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 ⚙️
| 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 🎯
A center pour keeps the stream in one spot. It is gentle and stirs the bed less, which is 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. 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. 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.
