Three Pulse

Cafec Deep 27 Cafec by Onyx Coffee Lab

Onyx Coffee Lab's help guide inspires this Deep 27 version: a bloom followed by three centered pulses. The simple rhythm lets the tall coffee column extract evenly, aiming for a clean, repeatable cup without manual agitation.

Notes

Wait for the water level to fall through the deep bed before each pulse, but do not let the surface dry and crack. Keep the stream centered; wall spirals add bypass and prolong drawdown. If sweetness is muted while flow is fast, fine the grind slightly before introducing any swirl.
