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

OREA's wave paper is a 185×185 mm Japanese-stock wave filter. OREA states it's "compatible with any brewer that works with the Kalita Wave 185 filters, as this shape and size is the same" — fitting the V3, V3 MK2, Glass OPEN and V4 Narrow/Wide (not the Big Boy) — so it sits in the Kalita Wave 185 seat and interchanges with those papers. OREA publishes no bleach or flow spec, so both are left blank rather than guessed. (OREA also makes a flat "Type G" paper, catalogued separately.)
