Iced 8-Cup

Chemex 8 Cup Chemex by Chemex

Chemex's guide informs this Japanese-style flash brew for the Chemex 8-cup, extracting hot coffee directly over ice for rapid chilling. The goal is a bright, clean batch for sharing, with vivid aromatics and controlled dilution.

Notes

Place 400g in the carafe before brewing and distribute it beneath the filter so hot coffee chills immediately. Use 50g, 530g, and 96°C as written; grind finer if dilution leaves the cup hollow, then swirl thoroughly before serving.
