Choose the right cranberry drink
Sweetened cranberry juice cocktail supplies the balance intended here. Pure unsweetened cranberry juice is much sharper; it is not an equal flavor substitution. Chill both juices and the sparkling water before mixing. Cold ingredients let the drink reach the table with less melting ice and less dilution.
The recipe makes 600 milliliters of liquid, or about 300 milliliters per glass before ice. Use the specified roomy 16-fluid-ounce glasses so there is space for the ice and orange slice. If a glass is smaller, divide the drink into more glasses instead of filling to the rim.
Keep the moon in place and the fizz lively
Wash the orange before cutting the thin garnish rounds. The small slit lets a round rest on the rim without a cocktail pick. Save the remaining orange for eating or another use. Keep decorative objects around the glasses rather than putting non-food ornaments in the drink.
Mix the two juices first, add ice to the glasses, and pour the sparkling water last. One gentle stir combines the layers without deliberately stirring away the bubbles. A flat finished drink cannot regain its sparkle just by adding more ice; make each round close to serving.
Prepare a second round
For the six-drink quantities in the recipe note, refrigerate the combined juices in a covered jug and keep the sparkling water separate. At service, divide the juice base among six glasses and add 1/2 cup sparkling water to each. That keeps the original proportions while allowing guests to arrive at different times.
Keep opened juices chilled according to their labels. If a guest needs to check an ingredient, keep the original bottles available. The drink is alcohol-free, but that label alone does not answer questions about a particular juice blend or allergy.
