ColdBrew Instructions

• Initially, boil new filters in fresh water to clean and shrink for 10 minutes. 
• Fit ColdBrew filter over lip of wide mouthed canning jar.
• Add desired amount of coarsely ground coffee. 
• We recommend 3 ounces by weight (1 cup dry) per 32 ounce serving. 
• Wet the dry coffee and let set for 30 seconds, allowing the water to fully penetrate the coffee.
• 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.
• For best cold-brew results, steep 6-10 hrs (32 oz.), 12-16 hrs (64 oz.).
