Presented through Kalita's Wave 155 product guidance, this dark-roast approach uses gentle, cooler extraction in the compact flat-bottom brewer. It targets a smooth single cup with developed sweetness, full body, and restrained bitterness.

Notes

Use 88°C and a slightly coarser grind than for light coffee. Pour with a low, quiet stream and avoid repeated swirling; if roast bitterness remains prominent, coarsen before lowering temperature further.
