In a medium pot, combine water, sugar, peach slices, juice (and cinnamon sticks if adding). Bring to a boil.
Reduce heat and allow to simmer for 5 minutes.
Remove from heat and allow to sit until cooled to room temperature.
Pull out the cinnamon sticks.
If you want this totally smooth with no fruit, strain liquid into a large jar or container (with lid), pressing on solids to get every bit of liquid. OR place a some of the peaches in your jars (or large container) and pour in the liquid)
Add in the Peach Schnapps and Everclear
Stir or shake to combine.
Refrigerate for a day, then taste and adjust. Store in your freezer if not using within a couple of days. See notes about freezing.
Taste and adjust to your liking by adding more Everclear or Schnapps OR if you feel its too strong, add in ¼ cup of water or juice (or more) until it's to your liking.
Keeps in your fridge for up to 2 weeks. However before serving place it in your freezer (if it wasn't already there) for ice cold moonshine, YUM!!
