Why Ratios Matter
The SCA (Specialty Coffee Association) recommends 55–60g of coffee per litre of water for filter methods — approximately 1:17. Espresso is 1:2 (yield twice the weight in liquid). These are starting points — adjust to taste.
Weighing vs Scooping
Coffee scoops are unreliable because ground coffee density varies by roast level, grind size, and origin. A medium roast fills a scoop differently than a dark roast. A simple kitchen scale is the most important upgrade you can make to your coffee setup.
Grind Size and Ratio
Grind size and ratio interact — a coarser grind extracts more slowly, so you may need a slightly higher coffee dose or longer contact time to achieve the same strength. If your coffee is weak, try reducing water before changing the grind.
