For 2 cups of medium auto-drip, you need 29.6 g of coffee.

  • Use 29.6 g of ground coffee (about 5.4 tablespoons) and 474 ml of water.
  • Your ratio is 1 : 16.0: for every gram of coffee you use 16.0 ml of water.
  • Use a medium grind, similar to coarse sand.
  • Your bag yields about 17 cups at this ratio and strength.

Next stepWater temperature matters almost as much as ratio: aim for 90 to 96 degrees C (195 to 205 degrees F) for most hot-brew methods.
