Initially, boil new filters in fresh water to clean and shrink for 10 minutes.
Fit ColdBrew filter over lip of a canning jar.
Add desired amount of coarsely ground coffee. We recommend 3 ounces by weight (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, to fill.
Close filter by gathering the top of fabric together, wrapping the strap around the gathered neck of the filter, and pass through the attached ring.
Times vary with volume of brew and ambient temperature. Warmer temperatures and shorter brew times yield a brighter and less extracted brew. Long cold soaks produce rich and smooth brews.
