Toss the blueberries into a cocktail shaker and muddle them until they’re crushed and juicy. Don’t worry about getting it perfect.
Add vodka, lime juice, and simple syrup (if you’re using it) to the shaker along with the smashed berries.
Fill the shaker with ice and shake hard for about 15 seconds. You want it nice and cold.
Strain everything into a copper mug or glass packed with fresh ice. Use a fine mesh strainer so you don’t get too much pulp.
Top off with ginger beer and give it a gentle stir with a bar spoon.
Garnish with a lime wheel, some extra blueberries, and a mint sprig. Looks great, tastes even better.
The drink should show off a pretty purple-blue color from the berries. Serve right away while it’s still cold and fizzy.
