Crystal Eye Pulse

Timemore's Crystal Eye guide offers this multi-pulse method to use the cone's staged rib structure and flow. Repeated additions refresh the slurry while managing bed depth, producing an extracted cup with balanced sweetness, clarity, and body.

Notes

Keep pulse size and pour height consistent so each addition contributes similar agitation. Wait for the water level to fall without exposing the bed completely; if the final pulses drain much more slowly, coarsen the grind or pour more gently.
