Thanks to the flat bottom and three holes in the bottom of the Kalita dripper is achieved even extraction, because the ground coffee is evenly distributed in an even layer. More
Wave like shape of the paper filter ensure that the coffee is in minimal contact with the wall of the dripper, so the main impact to the extraction has the way of the pouring and not the shape of the dripper. You can brew up to 500 ml with this Kalita Wave 155. For brewing use Kalita 155 paper filters. We suggest to rinse the paper filter with hot water before brewing.
