Add the bourbon, cider, cinnamon, and lemon wedges (give them a little squeeze) to a shaker or jar with some ice. Shake well, then strain the drink into a glass with more ice. Taste, and add more lemon wedges if desired.
Fill the glass with an inch or so of club soda, stir, and drink!
This recipe is for one. To make in advance, combine as many of the first 4 ingredients as you need, shake, and strain. Pour over ice in glasses before serving and top with club soda.
