The Kalita Wave Series includes Wave Drippers and the the all in one brewer. The flat bottom design of the Kalita Drippers is engineered to provide even extraction from your grind. The wave shape of the Kalita pour-over coffee dripper is designed to insulate the slurry so it does not lose heat. Offered in ceramic, steel or glass, the testament to how well this designs works is in the flavor of the coffee Kalita equipment brews. Convenience, form and function come together in the Kalita Wave Style 185 Brewer. The flat bottom wave dripper is made from stainless steel and drips directly into the carafe. The wave shape of the dripper insulates the brew mass so it doesn’t lose heat.
