Place apple slices into a large stockpot and add water just until the apples are covered(approximately 4 cups).
Slowly boil the apples for approximately 25 minutes - the apples should be soft.
Place a filter in a sieve and gently mash the apple/water mixture over a bowl/pot for the juice to be collected. *If you don't have a sieve, line a strainer with a few layers of cheesecloth and let drain for at least 2 hours.
Taste the juice - if it is too strong you can add additional water to dilute.
Keep in refrigerator for up to a week. Recipe courtesy of Old World Garden Farms
