How it brews
The flat-bottom sibling of the FAST cone: a smooth, non-fluted paper using the same abaca technology, sized S (≈Kalita 155) and M (≈Kalita 185) for wave-style flat drippers, plus a larger size for basket machines. Because the wall is smooth rather than pleated, Sibarist markets it as keeping water in even contact with the whole bed and reducing bypass while still draining fast — a mechanism claim from the maker, not a measured result. It drops into a Kalita Wave 155/185 seat, so it's an option anywhere those papers fit. Single-use, made in Barcelona.
