The Wave Series from Kalita is the premier coffee dripper available on the market. The flat-bottom coffee bed geometry, patented "Wave" filter, and three-hole design work together to provide an even extraction that makes brewing a perfect cup accessible and easy. Brew directly into a cup, or mount it on a brew stand (like a TruBru). We recommend this size (#185) for brewing about 26-45 grams of coffee, yielding between 16 and 26 ounces of brewed coffee.
