Fill a champagne flute halfway with champagne or sparkling wine.
Pour a shot of raspberry-infused vodka over the top.
Garnish with raspberries or rosemary sprig.
Notes
If you don't have raspberry-infused vodka, don't fret! You can use a shot of regular vodka with freshly squeezed raspberry juice. Take about a cup of raspberries and squeeze through cheesecloth over a bowl.
