Coffee concentrate

Method

Coffee concentrate

  1. 1

    Combine coffee and water

    Add 1 cup coarsely ground coffee to a large jar or pitcher. Pour 4 cups cold filtered water over the grounds, ensuring all grounds are saturated. Give it a gentle stir for 10–15 seconds to make sure there are no dry pockets.

  2. 2

    Steep

    Cover the jar or pitcher and let the mixture steep at room temperature for 12–16 hours. For a quicker, brighter flash-brew-like result you can steep 6–8 hours, but longer will yield a smoother concentrate.

  3. 3

    Filter

    After steeping, strain the coffee through a fine-mesh sieve lined with a coffee filter, double layer of cheesecloth, or a nut-milk bag into a clean container. If needed, strain a second time to remove fines. You should end up with ~3–4 cups of concentrated cold brew.

  4. 4

    Refrigerate

    Chill the concentrate in the refrigerator for at least 1 hour before serving, or use immediately over ice if preferred.

Ice & serving

  1. 5

    Fill two serving glasses with ice (about 1 cup ice per glass). Pour the cold brew concentrate over the ice, filling each glass about three-quarters full.

  2. 6

    Dilute to taste with cold water or milk (about 1/4 to 1/2 cup per glass). Taste and add simple syrup or preferred sweetener if desired (about 1 teaspoon per glass). Stir gently to combine.

  3. 7

    Serve immediately. Store any leftover concentrate refrigerated for up to 10 days; dilute only when ready to drink.
