- The flat-bottom batch paper for Fellow's Aiden, sized for 8-12 cup brews in the flat-basket family. The wide, flat bed is the batch-brew geometry; it fits flat-basket seats and interchanges with other basket papers of that fit, not with the Aiden's single-serve cone. Fellow publishes no flow class, so we leave flow unrated. It's an everyday single-use paper with no special care beyond seating it flat.

- How it brews
- The B3 grade of Sibarist's abaca flat-bottom paper (associated with Matt Winton's flat-bed method), in S and M. Unlike the FAST papers, B3 is a lower-porosity sheet Sibarist rates as medium flow, trading some drainage speed for more body and retention across the flat bed. That medium class is the maker's own framing, not independently measured. It fits the flat-basket seat and interchanges with other flat papers of that fit; a pre-brew rinse is common.
