How it brews

The Graycano is a conical cast-aluminium dripper, and the GC01 is its own size-2 cone paper tuned to the dripper's "Lava Rib" geometry. Graycano states that V60 size 02 and Melitta 102 filters also fit the dripper, so we record a V60-cone seat as the closest match; the GC01 is a true cone. No published flow rating, so flow is left unrated. (This is the standalone Graycano brand, not GINA's cone papers.)

How it brews

A budget reusable stainless cone that fits both V60-style cones and the Chemex, aimed at people who want a metal filter without the premium of an Able Kone. As with any metal filter, the mesh lets oils and fines through for a fuller, more sediment-heavy cup than paper, and it drains fast enough that a coarser grind usually behaves better. The "fast" rating is community consensus, not a lab number. It's a zero-waste, one-buy option; the trade against paper is clarity and a clean base.
