Coffee Brewing Time Guide
Pour Over (3-4 min)
Start with a 30-second bloom, then pour water in slow concentric circles. Total brew time should be 3-4 minutes for a clean, bright cup. Use medium-fine grind (like table salt) and water at 200F (93C). Adjust grind size if timing is off.
French Press (4 min)
Steep coarse grounds for exactly 4 minutes, then press slowly. This full-immersion method extracts rich body and oils that paper filters remove. Going past 5 minutes over-extracts, creating bitterness. Serve immediately after pressing.
AeroPress (1-2 min)
The versatile AeroPress works with 1-2 minute steep times depending on your recipe. Standard method: 1 minute steep + 30 second press. Inverted method: 1.5 minutes steep + 20 second press. Use medium-fine grind and water at 185-205F.
Brewing Method Comparison
| Method | Time | Grind | Temp |
|---|---|---|---|
| Espresso | 25-30 sec | Very fine | 200F / 93C |
| AeroPress | 1-2 min | Medium-fine | 185-205F |
| Pour Over | 3-4 min | Medium | 200F / 93C |
| French Press | 4 min | Coarse | 200F / 93C |
| Moka Pot | 4-5 min | Fine-medium | Stovetop |
| Cold Brew | 12-24 hr | Extra coarse | Room temp |
The Science of Coffee Extraction
Coffee extraction follows a predictable order: acids dissolve first (sour notes), then sugars and oils (sweetness, body), and finally bitter compounds (tannins, caffeine). The goal is 18-22% extraction - enough to get sweetness without bitterness. Time is your primary control variable.
Under-extracted (too fast): Sour, thin, lacking sweetness. Grind finer or brew longer.
Over-extracted (too slow): Bitter, astringent, hollow. Grind coarser or brew shorter.

❓ Coffee Timer — Frequently Asked Questions
How long should a pour over coffee take?
A pour over coffee should take 3 to 4 minutes total brew time for a standard 300ml cup. Start with a 30-45 second bloom (wetting the grounds), then pour in slow circles. If it drains faster than 3 minutes, grind finer. If slower than 4 minutes, grind coarser. The ideal water temperature is 195-205F (90-96C).
How long to steep French press coffee?
French press coffee should steep for exactly 4 minutes. Add coarsely ground coffee (ratio 1:15 coffee to water), pour water at 200F (93C), stir once, place the lid on without pressing, and wait 4 minutes. Press slowly over 15-20 seconds. Longer than 5 minutes produces bitter, over-extracted coffee.
How long does cold brew coffee take?
Cold brew coffee takes 12-24 hours of steeping in cold or room temperature water. The standard ratio is 1:8 coffee to water for concentrate (dilute 1:1 before drinking) or 1:15 for ready-to-drink strength. Steep at room temperature for 12-16 hours or in the fridge for 18-24 hours. Strain through a fine mesh filter or cheesecloth.
