The Kalita Wave 102's flat bed and three small holes meter the water's descent, giving a slower, more even extraction that's forgiving of pour technique. Over 25g of medium-coarse coffee, start with a 60g bloom to release gases, then pour in gentle spirals — 140g, then two 100g pours to 400g total. The thick ceramic body holds heat for a stable temperature throughout. If the brew runs past ~3:30 grind coarser; if faster, grind finer — flow time is your main dial for balance.
