What is the golden ratio for drip and pour-over coffee?

The Specialty Coffee Association (SCA) golden cup standard is a 1:16 to 1:17 ratio (1 gram of coffee for every 16 to 17 grams of water). For a standard 12 oz mug (~350ml water), use approximately 21 to 22 grams of ground coffee.

What ratio should I use for French Press coffee?

French Press immersion brewing uses a slightly stronger ratio between 1:12 and 1:15 with coarse grind. For 500ml of water, use 35 to 40 grams of coffee with a 4-minute steep time.

Frequently Asked Questions

Why is weighing coffee in grams better than tablespoons?

Coffee beans vary significantly in density depending on origin and roast profile. Dark roasts are lighter and less dense than light roasts; 2 tablespoons of dark roast might weigh 11 grams while light roast weighs 15 grams. A $15 digital gram scale guarantees consistent extraction every morning.

What is the coffee "Bloom" phase?

Fresh roasted coffee contains trapped carbon dioxide gas ($CO_2$). Pouring twice the weight of coffee in hot water (e.g. 50g water for 25g coffee) and waiting 45 seconds lets the gases release, ensuring the water extracts soluble coffee compounds evenly without channeling.
