Remove from the heat, and discard the cinnamon sticks.
Allow the mixture to cool to room temperature, then stir in the grain alcohol.
Pour into quart-size canning jars, seal with the lids and rings, and refrigerate until ready to serve.
**NOTE: This recipe that it makes 5 quarts! You can store this in the refrigerator for at least 6 months. I've heard of people storing it for a year or more.
