What you will need

  • Cold Brewer
  • Grinder
  • Coffee
  • Fresh water
  • Scale
  • Whisk or Spoon
  • Cup
  • 01
    Measure & Grind

    Measure and grind 250 grams of freshly roasted coffee beans to the consistency of coarse sea salt.

    Peet's tip: 250 grams is just over a half-pound of coffee. A finer grind will cause over-extraction during the brewing process.

  • 02
    Prepare & Brew

    Add ground coffee to the cold brewer filter and then slowly pour in 1 liter of cold, freshly filtered water. Allow the grounds to bloom for at least 30 seconds. Then carefully pour in the remaining ¼ liter (250 ml) of fresh, cold water.

    Peet's tip: Use the back of a spoon or whisk to gently push any dry grounds below the surface of water until all of the grounds are saturated.

  • 03
    Wait

    Let the coffee brew for a minimum of 12 hours. You can brew at room temperature or in your refrigerator.

  • 04
    Drain

    Lift the filter and let the cold brew concentrated drain completely before discarding the grounds.

  • 05
    Enjoy

    To serve, dilute 1 part cold brew concentrate with 2 parts cold water. Adjust the strength to your taste.
