How to make the perfect Cold Brew

Brewing cold from start to finish results in bold, smooth, refreshing coffee with lower acidity than coffee that’s been brewed hot and then iced.

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.
