How it brews

The B3 version of Sibarist's abaca cone paper for V60-style cones, in S (01) and M (02). Where Sibarist's FAST papers are cut for high permeability and clarity, B3 is a lower-porosity sheet that Sibarist rates as medium flow — the trade being more contact time, more body and more retention on the same cone. That medium class and its low clog sensitivity are the maker's own framing, not measured here. It fits the V60-cone seat and interchanges with other cone papers there; a pre-brew rinse is the usual habit.

How it brews

An abaca-forward paper (abaca fibre plus European-pine cellulose and a plant-based PLA binder) for V60-style cones, made in Barcelona in S/M/XL. Sibarist positions it as draining meaningfully faster than a standard cone paper, the idea being that you can grind finer for more extraction without choking the bed — that fast, low-clog framing is the maker's own, not independently measured here. Despite the durable feel it's sold single-use; the rinse-and-reuse you'll see online is a community habit, not a Sibarist claim. If your brews routinely stall, this is the paper that most directly buys back drawdown speed on a cone.
