Pulse Brew

Cafec Deep 27 Cafec by CAFEC

CAFEC's pulse approach for the Deep 27 keeps the water level low across many small additions. Lighter agitation than the stir method limits bypass and emphasizes clarity while the narrow bed maintains extraction.

Notes

Use small, centered pulses and let the slurry settle between them without exposing the bed. Keep kettle height and flow consistent, because extra turbulence accumulates quickly over many additions. If the cup lacks sweetness, fine slightly; if it tastes rough, reduce agitation first.
