Step 1: Pour 1 3/4 cup ground coffee into a pitcher.
Step 2: Pour 4 cups of water into the pitcher.
Step 3: STIR.
Step 4: Cover with plastic wrap and let steep for 12 hours.
Step 5: Remove plastic and place a cheese cloth (I use a few layers, if you use to many, your cold brew won't go through) over a jar, beverage dispenser, or an additional pitcher. You may want to tie it down with a rubberband. Pour coffee over the cloth.
Store in the refrigerator in mason jars. Now simply add ice and serve as desired!
Immediately rinse your cheesecloth in hot water or place it in hot water to soak until you have a chance to wash it. After soaking, rinse again. Try to remove as many bits of food as possible before you start to wash it.
Use only food safe soaps since regular household soaps contain toxic chemicals that may soak into the cotton fibers and later come into contact with your food.
Lemon juice, white vinegar and baking soda can also be useful for loosening up crusty bits and removing stains. You can add any one of these ingredients to soaking water. Use 1/2 cup to 1 cup per gallon of water, depending on how grimy the cheesecloth is. You can make a baking soda paste to scrub out stubborn stains. Be sure to rinse the cheesecloth thoroughly, because even lemon juice and vinegar may attract pathogens or fruit flies.
Dry the cheesecloth in a hot dryer, or hang it outside to dry in the sun if you have adequately hot temperatures to dry it quickly.
