Coffee Extraction

Coffee Extraction:

In brief, ideal yield is widely agreed to be 20%±2% (18%–22%), while ideal strength (for brewed coffee) varies between 1.25%±.10% (1.15%–1.35%) in American standards, to 1.40%±.10% (1.30%–1.50%) in Norwegian standards, with European standards falling in the middle at 1.20%–1.45%). This is most easily achieved with a brewing ratio of 55 g/L (55 grams of coffee per 1 L of water) in American standards, to 63 g/L in Norwegian standards, yielding approximately 14–16 grams of coffee for a standard 240 ml (8 oz) cup.
