    ColdBrew Instructions

    • Initially, boil new filters in fresh water to clean and shrink for 10 minutes.
    • Fit ColdBrew filter over the lip of a wide-mouthed canning jar.
    • Add desired amount of coarsely ground coffee. We recommend 3 ounces by weight or 1 cup dry per 32-ounce serving. 
    • Wet (bloom) the dry coffee and let set for 30 seconds, allowing the water to fully penetrate the coffee grounds from the center. This is necessary to maximize flow and to avoid dry pockets and weak brew.
    • Add filtered water in batches or very slowly, until jar is full.
    • Close filter by gathering the top of fabric together, wrapping the strap around the gathered neck of the filter, and passing through the attached ring.
