Why Strength Matters

Extraction Science

Coffee strength is determined by the ratio of coffee to water. The SCA Golden Cup Standard recommends 1:15 to 1:18 for optimal extraction and flavor balance.

Environmental Factors

Altitude affects water boiling point and extraction rates. Our calculator adjusts for elevation, ensuring perfect brewing from sea level to mountain peaks.

Water Quality Impact

Water TDS (Total Dissolved Solids) dramatically impacts extraction. Ideal brewing water has 150 ppm TDS for optimal flavor extraction and clarity.
