From Highlands to Cup

The Kalita Wave is a flat-bottomed pour-over dripper designed to produce a more even extraction than conical shapes allow. Made by Kalita, a Japanese coffee equipment manufacturer founded in 1958, the Wave launched in 2010 with a distinctive design that broke from the cone shape that had dominated specialty pour-over since the V60's release six years earlier. The fluted paper filter, with its 20 ridges, gives the Wave its name and its distinctive appearance.

The bed of coffee sits flat rather than cone-shaped, and three small holes in the base control the drainage rate. These two design choices work together to deliver a cup with a different character than a V60 or Chemex. The flat bottom distributes water contact more evenly across the coffee bed. Each part of the bed sees roughly the same water flow, which reduces the channeling that sometimes occurs in conical drippers when water finds a path of least resistance. The three small holes, rather than one large one, slow and steady the flow. The cup tends to arrive with good clarity, rounded body, and a balance that many brewers find forgiving.

The Wave found its strongest early adoption in American specialty cafés that wanted V60-quality results without V60-level technique demands from their baristas. Coava in Portland, Stumptown, and Blue Bottle helped popularize it during the early 2010s. The 2014 World Brewers Cup champion, Stefanos Domatiotis, used a Kalita Wave for his winning brew, validating the dripper at the highest competitive level. The dripper now appears in stainless steel, glass, and ceramic, with the steel 185 size becoming the most common choice in professional settings.

The Kalita Wave is often described as the dripper that produces consistent cups with less technique than a V60 demands. Café de Volcán considers the Kalita Wave a welcoming pour-over — a method whose design does more of the work for the brewer, allowing the coffee itself to express without depending as heavily on pour technique.
