Tips

Golden Cup Standard: SCAA recommends 1:16.67 (55g per liter) for optimal extraction.

Yield: Coffee absorbs roughly 2x its weight in water. A 300ml brew with 18g coffee yields ~264ml.

Measurement tip: 1 tablespoon of coffee is approximately 5g. Use a scale for consistency.

Adjusting: Start with the recommended ratio, then adjust. More water = lighter, more coffee = stronger.
