A full, level coffee scoop holds approximately two tablespoons of coffee grounds. A scoop of coffee should be used for each 6 ounces of water used. The number of scoops of coffee needed to achieve a certain strength of coffee depends on the grind of coffee used.
A scoop of finely ground coffee makes a stronger cup of coffee than a scoop of coarsely ground coffee. It may take more coarsely ground coffee to achieve the same strength and taste of a finely ground coffee. The type of cup should also be considered when determining how much coffee to use. A coffee cup, roughly the size of a teacup, is approximately 6 ounces. A coffee mug averages between 8 and 9 ounces. To create the same strength coffee in a coffee mug, it may be necessary to use 1.5 standard scoops of coffee.
