The proper coffee / water ratio is 11 g. of coffee per 6 oz. of water. If you prefer to use coffee scoops, use a 2 TBSP scoop per 6 oz. of water, but keep in mind if you use a scoop, that you may need to add a little extra dark roast because the "proper" way to measure is by weight, and dark roast weighs less, so you use a bit more volume.
