Cold Brew recipe - Everyone prefers their cold brew slightly differently, personally I prefer to use: - 3/4 cup of ground coffee to 4 cups of water - Steep in the fridge for 36 hours Caring for your coffee sock: - Hand wash with soap before first use - After use, it will be much easier to untie & dump out the grounds once it has dried. - Rinse out thoroughly with hot water - Hang to dry completely before storing.
