A starting point from Kurasu
This Kalita Wave guide uses Kurasu's 2023 recipe: 14 g of coffee, a coarse grind and 200 g of water at 92°C in a Wave 155. Three water additions build the brew, with an approximate finish between 02:05 and 02:15.
Record the brewer size and match the paper to it before comparing recipes. A small coffee dose creates a different bed in a Wave 155 and a Wave 185. Changing the dripper can therefore require another grind adjustment, even with the same coffee and water quantities.
| Setting | Reference recipe |
|---|---|
| Dripper | Kalita Wave 155 |
| Coffee | 14 g |
| Hot water | 200 g |
| Grind | Coarse |
| Temperature | 92°C |
| Input ratio | About 1:14.3 |
| Approximate finish | 02:05 to 02:15 |
Fit the paper carefully
Place a Wave 155 filter in the dripper and rinse it without crushing the pleated shape. Discard the rinse water. Add the coffee, level the bed and tare the whole setup on the scale. Make sure the server and dripper sit securely before pouring.
Filter fit is worth keeping consistent. A paper that has folded awkwardly or been pressed tightly into a different position can make the next brew harder to compare. Keep the pleats in their original shape and use the filter size intended for the brewer.
- Use the correct filter size.
- Record the grinder model and its setting alongside the description coarse.
- Keep rinse water outside the measured brewing water.
- Prepare enough hot water to complete all three additions.
Use the cumulative targets
The first two pours each add 30 g. The last adds 140 g, taking the scale from 60 g to 200 g. Kurasu specifies when each pour starts. Pour durations can vary with your kettle and flow rate.
| Start time | Water added | Cumulative scale target |
|---|---|---|
| 00:00 | 30 g | 30 g |
| 00:40 | 30 g | 60 g |
| 01:10 | 140 g | 200 g |
| About 02:05 to 02:15 | Let drainage finish | 200 g brewing water added |
Let the last pour remain controlled
Kurasu's method uses a more active second addition and a thin, central final stream. Use those motions when following this recipe; other Kalita recipes may use different pouring styles. Keep enough headroom in the paper and use a stream you can control comfortably.
Lift the dripper once the water has drained and mix the coffee before tasting. The final beverage mass is not the same as the 200 g input, because water remains in the grounds. If the brew finishes outside the reference window, record the time and taste before adjusting it.
Refine the recipe on your equipment
For a weak, sharp and unusually fast cup, test a slightly finer grind while leaving the dose and schedule fixed. If drainage slows dramatically, examine grind fines, filter fit and extra agitation before making several changes. Keep notes about both flow and flavor.
When changing brewer size or batch size, treat the result as a new version to dial in. Doubling every ingredient does not guarantee the same water depth, flow or timing. Once your baseline is enjoyable, compare it with V60 using the same coffee and clearly recorded recipes.
