The Perfect French Press Coffee Ratio


Want a great tasting cup of French Press Coffee? If so there is a little bit of math behind the scenes to give you the perfect amount of flavor.

Coffee to water ratio for the French Press is 1 gram of coffee for every 12 grams of water (1:12 ratio).

To calculate how much coffee you need, weigh the amount of water you want to brew and divide that by 12. That will give you the amount of coffee to grind

Use the table as a reference. Depending on how potent you want your coffee you can either add more water or grounds to your cup.

What is French Press Coffee?

Coffee made in the simplest way: a cup, a filter, and a funnel, without any makers or machinery.
The process involves slowly pouring a steady stream of hot water in a circular motion over filtered coffee grounds. This will extract all the flavors from the grounds directly into your pot.

Note: Filter ground coffee stands for roasted, then cracked to smaller pieces to be brewed easily coffee beans.

I say think of Pour Over Coffee as a manual brewing process and therefore more controllable so that you can fine-tune the taste to your preference.

Why does the water to coffee ratio matter?

It matters for the flavor of your coffee. Each coffee bean has a finite amount of flavor that can be extracted and you don’t want to ruin it by not properly brewing it.

If you use too little coffee grounds, you will have a diluted, watery cup. If you use too much, you’ll have a caffeine-loaded cup of coffee that may lack in the flavor nuances of fine specialty coffee.

But like I mentioned earlier, use the table as a reference as you will have your own preference of how your coffee should taste. Start with the ratio recommendations above and adjust by a few grams until you find the perfect ratio for you.
