💡 Expert Tips
Bloom Phase. For pour-over, pour 2x the weight of coffee in water first (e.g., 30g water for 15g coffee) and let it sit for 30-45 seconds. This releases CO2 gas and makes the extraction more even.
Water Temperature. Don't use boiling water (100°C). It burns the coffee. Aim for 93°C-96°C (200°F-205°F). Wait 30 seconds after boiling before pouring.
