Answer: How much coffee do you want to drink?
The ideal ratio to extract the best coffee flavors, using a pour-over or full-emersion brew like a french press, is anywhere between 1:15 and 1:17. This means for 1 gram of coffee you should use around 16 ML (or grams) of water. We recommend that you invest in a scale like this one made by Hario to dial in your coffee consistently. Good scales come with both a scale and timer built-in.
If you want to brew one cup of coffee using a pour-over, then try starting with a target of 20 grams of coffee to 320 grams of water, which is a 1:16 ratio. If you prefer your coffee a little lighter then use a 1:17 ratio and if you enjoy a more full-bodied coffee then try a 1:15 ratio. If you’re still not extracting all of the coffee potential that you desire then I would re-check your grind settings first.
Lastly, if you don’t have a scale you can try these commonly used kitchen hacks to help you measure your coffee weight:
- 4 tablespoons of ground coffee equals 21.2 grams
- 1/4 cup of ground coffee equals 21 grams
