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.

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.
