Mastering the Pour‑Over:
A Step‑by‑Step Guide with Brew Times
Focus on the technique of pouring. Emphasize how the BrewMetrics calculator provides the precise total brew time to aim for (e.g., 3:30-4:00 minutes), helping users diagnose if they're pouring too fast or too slow.
I. The Art and Science of Pour‑Over
The Hook: “You watched the YouTube video. You bought the fancy gooseneck kettle. You carefully poured in slow, concentric circles. And yet… your coffee still tastes hollow, sour, or just 'off.' What happened?”
The Frustration: Pour‑over looks simple. But the difference between a transcendent cup and a disappointing one often comes down to one variable most guides ignore: your total brew time.
The Revelation: “Your pour speed and pattern directly control your brew time. And your brew time determines whether you nail the extraction or miss it entirely.”
The Promise: “You'll learn exactly how to pour—a repeatable technique that hits the ideal brew window of 3:30–4:00 minutes. We'll use the BrewMetrics calculator to give you a precise target.”
BrewMetrics doesn't just give you a ratio—it gives you a target brew time based on your dose and desired strength. Think of it as your pouring GPS.
II. Why Brew Time Matters More Than You Think
The Extraction Curve
- < 2:30 → sour, salty (under‑extraction)
- 2:30–3:00 → light, tea‑like
- 3:30–4:00 → sweet spot
- > 4:30 → bitter, astringent (over‑extraction)
Pouring speed connection
Pour too fast: water rushes → sour, weak.
Pour too slow: water pools → bitter, harsh.
Pour just right: 3:30–4:00 sweet spot.

III. Before You Pour: The Setup Checklist
| Item | Why It Matters |
|---|---|
| Pour‑over cone (V60) | Flow rate & shape |
| Gooseneck kettle | Essential for flow control |
| Burr grinder | Consistent grind size |
| Scale with timer | Cannot do by eye |
| Paper filters | Rinse first! |
| BrewMetrics calculator | Ratio + target time |
Grind size: medium (table salt). Ultimate Grind Guide →
Ratio: 20g coffee : 300–320g water (1:15–1:16)
IV. The Anatomy of a Perfect Pour
Three phases: Bloom · Main Pour · Drawdown
🌼 Phase 1: The Bloom (0:00 – 0:45)
Pour 2–3x coffee dose (20g → 40–50g). Slow concentric circles. Bubbles = fresh.
💧 Phase 2: The Main Pour (0:45 – 2:30)
Continuous small circles, avoid edges. Finish total water exactly at 2:30.
⏳ Phase 3: The Drawdown (2:30 – finish)
Target 1:00–1:30 → total brew time 3:30–4:00. Flat bed = good.
V. The BrewMetrics Brew Time Target System
Ideal total brew time depends on dose. Use this table as reference:
| Coffee dose | Target range (BrewMetrics) |
|---|---|
| 15g | 2:45 – 3:15 |
| 20g | 3:30 – 4:00 |
| 25g | 4:00 – 4:30 |
| 30g | 4:30 – 5:00 |
Feedback loop:
✔️ Before target → pour faster or grind finer.
✔️ After target → pour slower or grind coarser.
✔️ Hit target → repeat!
VI. Common Pouring Mistakes
- 🔥 The Fire Hose: too aggressive → channeling. Fix: slow down.
- 🧱 The Wall Washer: pouring on filter edges → bypass. Fix: keep circles tight.
- ⏯️ The Interruptor: pauses → bed goes dry. Fix: continuous pour.
- 🏎️ The Speed Racer: water finished by 1:30 → over‑extraction. Fix: spread to 2:30.
- 😟 Nervous Nelly: too slow, finish at 3:00 → over‑extraction + cooling. Fix: confident stream.
VII. The Complete Pour‑Over Recipe Card
| Parameter | Setting |
|---|---|
| Coffee dose | 20g |
| Water total | 300g (1:15) |
| Grind size | Medium (table salt) |
| Water temp | 205°F light / 200°F medium / 195°F dark |
| Total target | 3:30 – 4:00 |
Timing breakdown
- 0:00 – 0:45 bloom 40-50g
- 0:45 start main pour
- 1:30 ~150g left
- 2:30 finish pour (all 300g in)
- 2:30 – 4:00 drawdown
- 3:30–4:00 done ✅
visual checklist
- ✓ bloom bubbled
- ✓ main pour continuous
- ✓ finished pour @ 2:30
- ✓ bed flat
- ✓ total time in range
VIII. Advanced: Pulse Pouring
Instead of continuous, add 50g pulses every 30s after bloom.
0:45 +50g · 1:15 +50g · 1:45 +50g · 2:15 +50g · 2:45 +50g → drawdown
IX. The BrewMetrics Connection
It turns vague advice into measurable feedback. Target time + finish time = diagnosis.
| Taste problem | Likely cause | BrewMetrics check |
|---|---|---|
| sour, weak | under‑extraction | total time < 3:15 |
| bitter, harsh | over‑extraction | total time > 4:15 |
| hollow, flat | uneven pour | check bed & timing |
X. Frequently Asked Questions
Q: Do I really need a gooseneck kettle? Yes. Flow control is critical.
Q: Brew time always too long? Grind coarser.
Q: Brew time always too short? Grind finer, or pour slower.
Q: Different dose than 20g? Use BrewMetrics, it scales target time.
