How to Make Cold Brew Concentrate

Learn how to make a smooth, low-acid, and highly-caffeinated cold brew concentrate at home. A simple, no-heat recipe for a refreshing coffee experience.

Ingredients

  • 1 cup (85g) of coarsely ground coffee
  • 4 cups (900g) of cold, filtered water

Instructions

  1. Step 1: Combine and Steep - In a large jar, combine the coffee grounds and water. Stir to ensure all grounds are wet. Cover and let it steep at room temperature for 12-18 hours.
  2. Step 2: Strain - Slowly pour the mixture through a fine-mesh sieve, cheesecloth, or a coffee filter to separate the concentrate from the grounds.
  3. Step 3: Store and Serve - Store the concentrate in a sealed container in the refrigerator for up to two weeks. To serve, dilute with water, milk, or ice to your desired strength (a 1:1 or 1:2 ratio is a good start).
