Pour Over Coffee Brew Time Calculator
Calculate pour over total brew time and pour stages by dose.
Get bloom, main pour, and total time for V60, Chemex, Kalita, and Origami drippers.
Pour Over Coffee Brew Time
Total brew time depends on dripper geometry, grind size, and total water mass. The classic specialty-coffee target:
Total brew time ≈ 2:30 to 3:30 minutes for a 250-300 g brew on a V60.
Standard pour over recipe (1:16 ratio):
- Coffee dose: 15-20 g
- Water: 240-320 g
- Bloom: 2× dose in water for 30-45 sec
- Main pours: 2-3 stages of equal volume
- Total time: 2:30 to 3:30
Pour stages by dripper:
| Dripper | Pour Style | Stages |
|---|---|---|
| Hario V60 | Continuous spiral | 1 bloom + 2-3 pours |
| Chemex | Slow, gentle | 1 bloom + 2 pours |
| Kalita Wave | Pulse pours | 1 bloom + 3-4 pulses |
| Origami | Versatile | 1 bloom + 2-3 pours |
| Clever Dripper | Immersion | 1 pour, steep, then drain |
Stage timing (typical 250 g recipe):
| Stage | Action | Time | Cumulative |
|---|---|---|---|
| 0:00 | Pour bloom (2× dose) | 5-10 sec | 0:10 |
| 0:10-0:45 | Bloom rest | 35 sec | 0:45 |
| 0:45-1:27 | Pour 1 (to 60% total) | 42 sec | 1:27 |
| 1:27-1:57 | Pour 2 (to 100% total) | 30 sec | 1:57 |
| 1:57-2:45 | Drawdown | 48 sec | 2:45 |
That is the schedule for a standard 18 g V60. Bigger doses stretch the pours and the drawdown, which is what the calculator adjusts for.
Adjustments by grind size:
- Coarser grind means water passes faster and the brew finishes early. If the cup tastes thin and sour, grind finer.
- Finer grind means more resistance and a longer brew. If you run past four minutes, coarsen.
Adjustments by total dose:
- Larger doses (25 g+): expect 30-60 sec longer drawdown
- Doses under about 12 g: expect 15-30 sec shorter
Why timing matters:
- Under 2 minutes: under-extracted, sour and weak
- 2:30 to 3:30 is the sweet spot, where extraction lands balanced
- Over 4 minutes: over-extracted, bitter and astringent
Pro tips:
- Rinse the paper filter through with hot water and pour the rinse away. It washes out the papery taste and warms the dripper at the same time
- Pre-heat the carafe and dripper
- Use a goose-neck kettle for slow controlled pours
- Stir or swirl the bloom to fully wet all grounds
- Stop pouring water about 15 seconds before target time: drawdown finishes the brew
