How it brews

Sibarist's abaca paper cut to the wave shape for Kalita-Wave beds, in S (155), M (185) and an L (8-12 cup) — offered in both the high-permeability FAST and the lower-porosity B3 grades. The wave geometry stands the bed on the fluted walls the way any Wave paper does, and it interchanges with Kalita-Wave papers of the matching size. Sibarist rates the FAST grade as fast-draining (its own claim, not measured here), the idea being you can grind finer for more extraction without choking the flat bed. Choose FAST for clarity and speed, B3 when you want more body and contact time on the same seat.

How it brews

Timemore's own paper for the Crystal Eye B75, a 155-size flat-bottom filter made from Japanese virgin pulp. The B75 is a flat-bottom (75° wall) brewer, and its paper is explicitly cross-compatible with the Kalita Wave 155 seat (and April Small), so it interchanges with those flat papers. Timemore states no flow class and there's no reliable within-seat ranking, so flow is left unrated.
