Using a french press is not that complicated, but it's tricky to get the right French press ratio of coffee to water, ensuring you get the best coffee flavor possible.
Start out by adding a large tablespoon of about 8 grams of coffee to one pot of water.
The ratio to start with should be 8 grams to coffee for every 200 ML or 6.7 ounces of water that you use.
Add boiling water to the pot and stir it gently, but make sure the water is not quite boiling or you could burn the coffee creating an unpleasant, acrid taste.
You want something more than lukewarm but less than boiling.
Reinsert the plunger into the pot, making sure you top as soon as you are about the water and coffee.
You do not want to plunge just yet.
Let things sit and brew for a few minutes.
Again, keep track of how long you brew, as this can also contribute to the strength of your coffee, and could be just as important as the ratio of coffee to water.
Over or under brewing could mean you have the right amount of coffee, but did not brew correctly.
After it brewed the right amount, press the plunger down carefully.
You’re done—just make sure to wash the French press with warm, soapy water, and don’t forget to keep track of what you liked and didn’t like, so you can tweak the coffee ratio for next time.
Hope this helps!
