I am making a French Press coffee from my pre-ground coffee that I get from my local coffee shop. I store it in an air-tight container and brew it like such
- Add 11 grams of coffee in the french press
- Add 225 ml of just of the boil water
- Mix and wait for 4 mins
- Scoop the top sludge after a small stir and wait for another 2-3 mins
What could be the cause of the coffee being too sour ?
