Pour Over Brew Time: The Complete Guide

By Coffee Ratio Calculator Guru · Updated January 2025 · 5 min read

A well-dialled pour over should complete in 2:30–4:00 minutes total, including a 30–45 second bloom. Use our brewing time calculator for target times by method. Brew time is how you diagnose your pour over — every minute outside the target window is telling you something specific about your setup.

The Bloom Phase

Every pour over should begin with a bloom: pour approximately twice the coffee weight in hot water (40ml for 20g of coffee) and wait 30–45 seconds. During this time, CO₂ trapped in freshly roasted coffee rapidly escapes, creating an expanding, bubbling crust. If your coffee doesn't bloom, it's too old — CO₂ off-gasses within 1–2 weeks of roasting. The bloom saturates all the grounds evenly, preventing dry pockets that cause channelling and uneven extraction. Your total brew time clock starts at the beginning of the bloom pour.

Target: 3:00–3:30 for Most Pour Overs

While the acceptable range is 2:30–4:00, the sweet spot for most pour over setups is 3:00–3:30 total from first pour to drain. This time, at a medium-fine grind and 93–96°C water, produces 18–22% extraction — the SCA's golden zone. If you're consistently outside this range, adjust grind size first: finer grinds slow draw-down (longer time); coarser grinds speed it up (shorter time).

Diagnosing Problems by Brew Time

Under 2:30 (too fast): grind is too coarse. Water flows through too quickly, under-extracting — sour, thin cup. Grind finer. Over 4:00 (too slow): grind is too fine. Water struggles to pass through the bed — bitter, harsh cup due to over-extraction. Grind coarser. If brew time is right but taste is off: adjust ratio. If ratio is right but body is wrong: check water temperature (hotter = more body-contributing compounds extracted).
