Place all the ingredients in a glass jar and mix well. Cover the jar with a cheese cloth and a rubber band. Keep away from sunlight, ideally store in the cupboard and let sit for 48 hours. Stir every 12 hours. Once you see the apples breaking down after 48 hours strain the fruit out and keep just the concentrate in a glass jar in the refrigerator. It should keep for up to 6 months.

To serve place 2 tablespoons of the concentrate into a glass and top with ice and soda water. Garnish with some rosemary and a cinnamon stick with a few slices of fresh apples.
