Chemex 3 Cup

Single Pour

Chemex 3 Cup Chemex by Chemex

Chemex's approach is simplified for the 3-cup brewer into a bloom followed by 1 count uninterrupted main pour. With little manual agitation, the method favors repeatability and a delicate, transparent cup from the thick paper filter.

Notes

Use a finer grind to supply extraction without repeated pulses, but keep the continuous stream gentle and centered so it does not excavate the bed. If flow chokes, coarsen slightly; do not compensate with aggressive stirring, which can lodge fines in the filter.
