This small and compact dripper lets you prepare a custom cup of coffee, brewed exactly to your liking. Expect strong and robust brews from this pour-over dripper. It has a unique flat-bottomed coffee bed, three small extraction holes, and a patented wave filter so hot water does not accumulate. The result is a rich and evenly extracted cup of coffee. This dripper is our most popular choice for camping & travel, and cafés love it for its durability. The Kalita Wave is a unique brewing process with tailor-made filters and brewers that provide foolproof pour over coffee extractions. The inside of this brewer features a wave design with a contrasting 20-wave filter that works rhythmically together to limit contact between each other so water can flow evenly and at just the right rate. Once the water reaches the flat bottom 3-hole design the brewer prevents water from accumulating so extractions are even and bitterness is dodged; the result is delicious coffee. Rarely are people disappointed with the results of a Kalita Wave Brewer for their even extractions and simple brewing process.
