Grind coffee one or two notches coarser than French Press setting. Coffee to water ratio is different from hot brewing methods. You will use 1.66 lbs coffee to 1 gallon of water. This is the same as 6.64 ounces of coffee to 1/4 gallon (one quart) of water. Grind coffee and mix with room-temperature water into large french press or beverage pitcher. Stir well and allow to sit for 12-18 hours. When you are ready to decant, spoon off grounds that have remained on top of brew and discard. Use a paper filter to keep grounds out of your brew. You can pour through a brew cone with paper filter or an auto-drip brew basket with paper filter. This is now a concentrate. When pouring a glass, mix with one part water and one part ice. Store concentrate in refrigerator for up to 2 weeks.
