Question 1

What is the correct coffee to water ratio?

Accepted Answer

Ratios vary by method: Espresso uses 1:2 (18g coffee to 36g water), pour over uses 1:15–1:17 (typically 1:16), French press uses 1:15, AeroPress uses 1:6–1:10, and cold brew uses 1:4–1:8 for concentrate.

Question 2

How many grams of coffee for one cup?

Accepted Answer

For a standard 250ml cup via pour over, use 15–16g of coffee at a 1:16 ratio. For a 300ml French press cup, use 20g. For a double espresso (60ml), use 18g.

Question 3

What ratio makes the strongest coffee?

Accepted Answer

AeroPress with a 1:6 ratio (15g coffee to 90ml water) produces the most concentrated drip coffee. Espresso at 1:1.5 (ristretto) is the most concentrated extraction overall.

Question 4

Does coffee ratio affect taste?

Accepted Answer

Yes. Too little coffee (high ratio like 1:20) produces weak, watery coffee. Too much coffee (low ratio like 1:10 for drip) produces overpowering, muddy coffee. The golden ratio for most drip methods is 1:15–1:17.
