Clean your jar and all utensils well
Fill your jar ½-¾ of the way up with apple pieces/scraps
In a separate container, stir together water & sugar until the sugar dissolves.
Pour over the apples, until they are completely covered.
Leave about 1 inch of headspace at the top.
Cover with a kitchen towel/scrap fabric and secure tightly with a rubber band.
Sit in a warm dark place for 2 weeks, stirring every few days.
Examine your ACV - if it has a pleasant smell already, you can discard the apple pieces. If it still seems to mostly be water with some apple, leave for another 2 weeks.
Strain apple pieces out, and allow the liquid to sit for about another 4 weeks. When your ACV has the classic vinegary taste, it’s ready! Leave it to stand until that point. The times can vary.
When you’re happy with your vinegar taste, store in the fridge for as long as you’d like.
