  • Blueberries: You can use fresh blueberries or frozen.
  • Sugar: This is how we will lightly sweeten the blueberry syrup. You can use maple syrup, honey, or any other sweetener if you like.
  • Gin: Any of your favorite gin brands. Infused or regular gin; any kind of gin works.
  • Triple sec: This popular citrus liqueur gives the cocktail a lot more flavor. Feel free to use a different type of citrus liqueur.
  • Lime juice: This will add a bit of tartness to this sweet cocktail. Always use fresh lime juice if possible, not bottled. You can also try fresh lemon juice.
  • Garnishes: I like to make my cocktails pretty with a sprig of mint, a lime wedge, or edible flowers.

How to Make Blueberry Syrup 

Making your own blueberry syrup brings this cocktail to a new level! The blueberry flavor is fresh and naturally sweet. Here’s how to make a batch of blueberry syrup.

  1. Combine the blueberries, water, and sugar in a small saucepan and bring to a light boil over high heat. Mash the berries with a fork or potato masher to release the blueberry juices. Stir to ensure the sugar dissolves.
  2. Reduce to medium heat and simmer for 5-7 minutes.
  3. Remove from the heat and pour the syrup through a fine mesh strainer. Use a spoon to press out as much juice as possible while straining out the blueberry skins.
  4. Allow the syrup to cool to room temperature before using it in a cocktail.

​Uses for Leftover Blueberry Syrup

If you find yourself with too much blueberry syrup, there are so many other delicious uses for it! I like to make a double batch and use it throughout the week.

  • Use leftover syrup in a delicious blueberry matcha latte
  • Drizzle over vanilla ice cream
  • Stir into plain yogurt to make a sweet and creamy blueberry yogurt
  • Make a blueberry mocktail with club soda, blueberry simple syrup, ice, and fresh mint leaves.


Give your blueberry gin cocktail a floral flavor by adding lavender. You can add dried lavender to the blueberry syrup or use half blueberry syrup and half lavender simple syrup.

Try this gin fizz with different fruits. You can follow the same method with any other type of berry! I love strawberry cocktails especially, like this strawberry mojito.

Add herbs to the cocktail. You can try a thyme sprig, fresh basil leaves, or fresh mint. Simmer them into the blueberry syrup to extract as much flavor as possible.
