So for 6 cups of water or about 5 1/2 cups of cold brew at double strength.

• 1 ½ quarts of filtered water 6 cups
• 6 oz coarsely ground coffee or about 3 cups
• A clean container large enough to hold it all I used an 8 1/3 cup, 67.5 oz jar.
• Paper coffee filters or cheesecloth
• Combine the water and ground coffee in a clean container and let sit for 12-22 hours. It will start to get bitter after 24 hours.
• Double strain through two paper coffee filters or several layers of cheesecloth.
• This is a concentrate so dilute before serving by double.
• This will keep in the fridge for a week or 2.
