Optimal Extraction Grids
Each brewing method requires specific parameters to achieve optimal extraction. Use these grids as reference for dialing in your equipment.
V60 Pour Over
Ratio: 1:16 (coffee to water). Multiple pour technique recommended for even extraction.
Chemex
Ratio: 1:15. Thicker filter requires coarser grind and longer contact time.
AeroPress
Ratio: 1:12. Immersion method with pressure extraction. Lower temperature prevents over-extraction.
Extraction Variables
Grind Size Impact
Finer grinds increase surface area and extraction rate. Coarser grinds require longer contact time. Match grind size to your brewing method's contact time.
Temperature Effects
Higher water temperature increases extraction rate of soluble compounds. Lower temperatures extract fewer compounds, resulting in lighter body and higher acidity.
Contact Time
Longer contact time allows more compounds to dissolve. Balance contact time with grind size and temperature to avoid over or under-extraction.
Brewing Method Comparison
Full contact between coffee and water throughout the brew cycle. Examples: French Press, AeroPress, Cold Brew.
Water flows through coffee grounds. Examples: Pour Over, Drip Coffee, Espresso.
Forced water through compacted grounds. Examples: Espresso, AeroPress (with pressure).
