1:10 ratio, 100 g coffee for this batch.

  • Use 100.0 g of coarsely ground coffee with 1000 mL of water.
  • After straining you will have roughly 800 mL of drinkable cold brew (absorption removes the rest).
  • That yields about 3.3 servings at your chosen size.

Next stepSteep in the fridge for 12 to 18 hours, strain through a fine-mesh filter or cheesecloth, and store for up to 2 weeks. Ready-to-drink cold brew can also be steeped at room temperature for 8 to 12 hours then immediately refrigerated.
