The Kalita Wave is a flat-bottom dripper with three small drain holes and a distinctive ridged paper filter. It was designed to address one of the V60's main challenges: the single central drain hole allows water to channel unevenly if pours are not precise. The flat bottom and three holes create a more consistent flow bed, making the Wave more forgiving of imperfect pouring technique — and consistently producing a sweeter, more balanced extraction.
The flat bed keeps grounds at a uniform depth across the entire dripper, which means water passes through roughly the same depth of coffee wherever it contacts the bed. This promotes even extraction. Three small drain holes (rather than one large one) slow the draw-down and extend contact time slightly compared to a V60. The wave filter — with its accordion-like ridges — holds the filter away from the dripper walls, reducing the seal effect that occurs in cone drippers and allowing air to escape freely as water flows through.
The V60 and Kalita Wave are the two most widely used manual pour-over drippers in specialty coffee. The V60 is more technique-sensitive: precise, controlled pours produce a clean, bright, complex cup. The Wave is more forgiving: a less precise pour produces a smaller variation in the finished cup. The Wave tends to produce a slightly fuller body and softer acidity than the V60 on the same coffee, which many drinkers prefer. For beginners, the Wave is the better starting point; for those who want maximum clarity and brightness, the V60 rewards the effort.
The Kalita Wave comes in 155 (1-2 cups) and 185 (2-4 cups) sizes. Both are available in stainless steel, glass, ceramic and plastic — stainless steel retains heat best and is the most durable. Use Kalita Wave filters specifically: the ridged design is what creates the air gap between filter and dripper. Standard cone filters do not work in the Wave. Rinse the filter with hot water before brewing to remove any paper taste and preheat the dripper.
Use a 1:15 to 1:16 ratio — 20 g coffee to 300-320 ml water is a common starting point for the 185. Grind medium-fine, slightly coarser than V60. Water temperature: 92-94°C. Bloom with 40 g water for 45 seconds, ensuring all grounds are saturated. Then pour in 3-4 even circular pours every 30-45 seconds, keeping the water level consistent and pouring directly over the centre of the bed. Avoid pouring directly onto the filter sides. Target a total brew time of 3 to 3.5 minutes. If brew time is much shorter or longer, adjust grind.
If the cup tastes sour or thin, grind finer or use hotter water. If it tastes bitter or drying, grind coarser or lower the temperature. If the flat bed is uneven after brewing (piles of grounds on one side), your pours were not centred — aim for slow, small circular pours directly over the bed centre. If brew time is very short (under 2 minutes), check that you are using the correct Kalita Wave filters — a standard cone filter in the Wave can restrict airflow and create channeling or, conversely, drain too fast if it collapses flat.
