Remove rotting or bruised parts of apple scraps.
Fill each 8 ounce mason jar ¾ full of apple scraps.
Fill a small pitcher with 1 cup of water. Use distilled or bottled water if needed.
Add 2 tsps of white sugar to the pitcher and stir well.
Pour water into jar, covering apples scraps + leaving 1 inch of headspace.
Cover top of jar with a coffee filter or cheesecloth, secure with rubber band.
Store in a warm dark place for two to three weeks.
Stir jars every three days, skim off grey or dark matter.
After two weeks, strain out apple scraps, keeping liquid.
Let liquid sit for another three weeks.
