Free 4 minute French press timer for perfect coffee. The industry-standard 4-minute steep for a rich, full-bodied cup with no over-extraction bitterness.
4 minutes is the consensus among baristas and specialty coffee roasters as the optimal immersion time for French press at 200°F. It allows full extraction of coffee's desirable compounds (oils, sugars, complex aromatics) while keeping bitter over-extraction minimal. James Hoffmann (world barista champion) recommends 4 minutes as the baseline.
5–7 minutes: noticeably more bitter and harsh flavor. The finely ground particles (fines) continue extracting and produce tannic, astringent notes. Over 8 minutes: very over-extracted, harsh, unpleasant. The key insight: once you press the plunger and leave coffee sitting on the grounds, it continues over-extracting — pour immediately after pressing.
Best practice (James Hoffmann method): stir at the beginning to ensure even saturation, let the crust form on top (grounds float), and then break the crust at 4 minutes (scoop off foam), wait 5 more minutes for grounds to settle, then pour WITHOUT pressing the plunger. This removes the need to press and reduces bitterness.
Coarse grind — similar to coarse sea salt. Finer grinds over-extract in 4 minutes and produce a gritty, muddy cup. If you only have a blade grinder (produces inconsistent particle sizes), reduce steep time to 3 minutes to compensate for the finer particles. Burr grinder set to coarse is ideal.
The standard ratio: 1:15 (1g coffee per 15g water). For a 12oz French press: 22g coffee + 330g water. Stronger: 1:12. Lighter: 1:17. Always use a kitchen scale for consistent results. Volume measurements (tablespoons) are inconsistent because coffee density varies by roast level.
