Dark Roast

Hario Suiren Hario others by Hario

Hario's Suiren guide offers this low-temperature direction for dark roasts. Its rounded, water-lily-inspired ribs encourage gentle drainage, seeking full body and developed sweetness without pushing roast bitterness or dryness.

Notes

Choose a coarse, even grind and use 88°C without aggressive agitation. Pour softly near the center; if smoky bitterness dominates, cool the water or coarsen slightly, while a flat cup may need a finer setting.
