1 gallon apple juice
1 gallon apple cider
3 cups white sugar
8 cinnamon sticks
1 (750 milliliter) bottle 190 proof grain alcohol (Everclear works best)

In a large pot, combine apple juice, apple cider, sugar and cinnamon sticks. Bring to a boil, then remove from heat and let cool completely.
When juice mixture is cool, Stir in the grain alcohol.

If you haven't tried this yet you owe it to yourself to give it a shot. Be careful because it tastes so good the alcohol will sneak up on you.
