Frequently Asked Questions

What is a good coffee-to-water ratio?

A common starting point is 1:16 (1 gram of coffee to 16 grams of water) for pour-over, 1:15 for French press, and much stronger ratios like 1:2 for espresso.

How does strength preference change the ratio?

Increasing strength lowers the water-to-coffee ratio, meaning more coffee grounds per gram of water, resulting in a bolder cup.

Can I use this for cold brew concentrate?

Yes, cold brew typically uses a much stronger ratio like 1:8 since it's often diluted before drinking.
