Three Pulse

Onyx pours in three almost-equal pulses spaced widely — minute apart rather than the tight 30–45 second cadence of pulse-pour recipes. The wider spacing lets each pulse fully drain before the next. Bloom plus a swirl. The Pro's tall bed needs the swirl to flatten before the first pulse. Higher brew temperature than other Deep Pro recipes here (95 °C) — Onyx's house style favours light to medium roasts where the heat helps unlock acidity through the long column. Pulses are circular but stay near the centre — no need to chase the hexagonal walls. Drawdown around 4:30. Onyx's V60 version typically runs 4:00; the Pro's dot ribs add about 30 seconds.
