Kalita was founded in 1958 in Nihonbashi, Tokyo. The wave drippers use a flat bottomed design to better ensure even extraction and with the use of the Kalita wave filter papers and their rippled airflow - we feel that the Kalita line of drippers produce some of the most well rounded cups in our dripper line up.
