Poinsettia Cocktail (Berry-Infused)

1. A few hours before making the drink, pour 1 cup of vodka into a glass and add the 6 blueberries, 2 blackberries, and 4 raspberries. Let the berries soak in the vodka until you're ready to make the drink. For maximum flavor, muddle the fruit through a tight strainer to extract as much juice as possible.
2. To make one cocktail: add 1 shot (approx. 1.5 fl oz) of the berry-infused vodka and 1 shot (approx. 1.5 fl oz) of pomegranate juice to a glass.
3. Fill the remainder of the glass with brut rosé champagne.
4. Garnish with some fresh berries and enjoy responsibly.
