How it brews

The Chemex-only bonded paper is heavy — the maker states it's "20-30% thicker than most of the competition" — which mechanically restricts drainage and traps fines and fats, giving the Chemex its signature slow, clean, tea-like cup. That slow draw is community consensus rather than a printed flow number; Chemex itself only claims "proper infusion time." The white version is cleaned in an oxygen bath (no chlorine bleach). Fold it so the triple-layer side sits against the pouring spout, and rinse well before brewing — thick paper carries the most papery taste if you skip that. Squares, circles and half-moon are the same paper in different cuts.

How it brews

A reusable stainless-steel cone that drops into a Chemex in place of the bonded paper. Metal lets oils and the finest particles pass straight through, so the cup lands far heavier and more textured than paper Chemex — closer to a French press in body, with more sediment in the base. Its perforated wall drains quickly, so it's usually paired with a coarser grind than you'd use on paper to avoid a muddy, over-fast run. Community consensus, not a lab number, sets the "fast" here. The trade you're making is body and zero waste against the paper's clarity.
