What Is Cold Brew Concentrate?

Cold brew concentrate is made by steeping coarsely ground coffee beans in cold or room-temperature water for several hours. The resulting liquid is a highly concentrated coffee extract that can be diluted with water or milk.

Benefits of Cold Brew Concentrate

  • Less Acidic and Bitter: Easier on your stomach and teeth.
  • Smooth and Rich Taste: Enhances the nuances of different coffee beans.
  • More Caffeinated: Provides an extra energy boost.
  • Shelf-Stable: Can be stored in your fridge for up to two weeks.



How to Make Cold Brew Concentrate at Home

Making cold brew concentrate at home is simple. Here’s what you need:

  • A large pitcher or jar with a lid
  • A fine-mesh sieve or cheesecloth
  • A coffee filter
  • Coarsely ground coffee beans (preferably from Aerial Resupply Coffee)
  • Cold or room-temperature water

Steps to Follow

  1. Measure Ingredients: Use a ratio of 1:7.5 (coffee to water). For 2 cups of concentrate, use 6 ounces of coffee and 3.5 cups of water.
  2. Combine Coffee and Water: Place the coffee grounds in the pitcher or jar, add water, and stir gently.
  3. Steep: Cover and let sit at room temperature for 12 to 24 hours.
  4. Strain: Strain the mixture through a sieve or cheesecloth. Discard the grounds.
  5. Filter: Pour the concentrate through a coffee filter to remove fine particles.
  6. Store: Store in an airtight container in the fridge for up to two weeks.
