How much coffee do I need for french press?

Hi Vasileia, this question is a bit tricky to answer. I prefer to use a scale to measure my coffee, so I tend to use 30 grams of coffee per every 350 grams of water. That's a 12:1 brewing ratio, which gets me a relatively strong and rich cup of coffee. Depending on your preference, I recommend adjusting the ratio adding less coffee per part of water. Bear in mind that brewing temperature plays a role here too, so if you still find that your brew is too strong to your taste, you can reduce a bit the water temperature. Hope it helps!
