Muddle the Blueberries: In a copper mug (or any glass if you don't have one), add the fresh blueberries. Using a muddler or the back of a spoon, crush the blueberries until they release their juices. This will give your cocktail that fresh blueberry flavor.

Add Vodka and Lime Juice: Pour in the vodka and fresh lime juice. If you prefer a slightly sweeter drink, add the optional simple syrup at this point.

Fill with Ice: Fill the mug with ice cubes to the top. This will chill your drink and give it that crisp, cold finish that’s key to any Moscow Mule.

Top with Ginger Beer: Slowly pour the ginger beer over the ice. The ginger beer adds a spicy kick that perfectly complements the blueberries and vodka.

Garnish and Serve: Stir the drink gently to combine all the ingredients. Garnish with extra blueberries, a slice of lime, and a sprig of fresh mint. Then, sit back and enjoy your Blueberry Moscow Mule!
