Combine the apple juice and cider along with the white sugar, brown sugar and cinnamon sticks in a very large pot.
Stir it constantly until all the sugar dissolves and it comes to a boil.
Reduce the heat and let it simmer for 1 hour. Your house will smell amazing in the process!
Remove it from the heat and let it cool completely. I let it sit for several hours.
Remove the cinnamon sticks.
Once it's completely cooled, add the Everclear alcohol and the whipped vodka. (this is where you want to taste it to make sure the strength is just how you like it. Feel free to add more or less vodka and Everclear based on your preference. Just make sure you add a 50/50 mixture of each. Meaning if you add a 1/2 cup more of vodka be sure to add a 1/2 cup more of Everclear also. The recipe is pretty mild. I like it a bit stronger so I almost always add another cup of vodka and another cup of Everclear.
Stir it completely and add the mixture to clean glass mason jars with lids and store in the refrigerator. If you like a strong taste of cinnamon feel free to leave a stick in the jar for extra flavor. I do this on a couple of jars myself. I love the taste of cinnamon.
