01 - In a shallow dish, combine the granulated sugar, ground cinnamon, and coarse sparkling sugar, if using. This mixture will be used to coat the glass rims.
02 - Use the lime wedge to moisten the rim of each of the four serving glasses. Gently press the moistened rim into the cinnamon-sugar mixture, rotating to ensure an even coating.
03 - Fill each prepared glass generously with ice cubes.
04 - In a pitcher, blend the chilled cranberry juice, cream soda, club soda, fresh lime juice, and simple syrup. Stir briefly to integrate the flavors without over-agitating.
05 - Evenly distribute the mixed beverage into the ice-filled, rimmed glasses. Adorn with fresh cranberries and lime slices, if desired. Serve immediately for optimal effervescence.
