Pour the juice into a clean 2L jar. Quarter the 2 organic apples and the 2 organic oranges leaving the skin on both (these provide natural yeasts and sugars). Roughly chop the thumbsized piece of ginger again leaving the skin. Add the cinnamon quills, star anise, cloves and chopped ginger along with 200 ml of water. Close the lid and leave to ferment for 2-3 days
