Question: how much coffee do you need for 8 cups?
Answer: Secondly, if you want to be really precise, you can get some digital scales that are precise enough to weigh your coffee to the nearest gram, or better. This means that if you have an 8-cup coffee maker, you want to pour 8 x 6 ounce cups of water in the reservoir and 8 level scoops of coffee to the filter basket.
