Place unopened filters of our Just Black coffee into a sealable container. Add 6 oz. of cold water per each filter. We recommend 2 filters for a 16 oz. mason jar.

Seal your container and let your filters brew overnight (or at least a minimum of eight hours) in your refrigerator. 

Remove the filter from your container. Add your desired amount of ice and stir. Congrats, you've just made your own cold brew!
