Two of the things that most scream “summer” are refreshing cocktails and fresh berries. Combining the two just makes sense (like this strawberry mojito!). 

If you find yourself with lots of blackberries and a hankering for a blackberry beverage, look no further. This simple blackberry syrup for cocktails is easy to whip up and it makes for one delicious drink. 

Blackberry Syrup for Cocktails

Making homemade cocktails is a fun way to save money and get creative in the kitchen. While there is a wide variety of store-bought cocktail syrups available, making your own is more economical, healthier, and tastier. Homemade syrups are a great way to level up your cocktail making and they are surprisingly easy to make!

Whether you have an abundance of fresh berries or you just want a delicious seasonal cocktail, this syrup is a great one to have on hand. With just four simple ingredients, you can make blackberry cocktails that are loaded with rich, fresh flavor.

Fresh blackberries: The main flavor base for this syrup, blackberries offer a delightful, sweet flavor and a rich purple color. You can use frozen blackberries if fresh blackberries are expensive, unavailable, or out-of-season.

Raw honey: We are sweetening this syrup with honey because it provides a delicious, robust flavor and is a bit healthier. Feel free to substitute cane sugar, brown sugar, or maple syrup if you prefer. 

Fresh lemon juice: A splash of lemon juice balances this syrup and makes the flavor of the blackberries pop. You won’t taste it, but it does make a difference in the overall flavor. You can also use lime juice for similar results.

Uses for Blackberry Syrup

This versatile syrup is a great addition to a variety of food and beverage options. You can use it for anything that sounds good, but here are my favorite ways:

  • Make your favorite cocktails with a fresh berry twist. I like this syrup in a blackberry bourbon smash, blackberry Moscow mule, or a blackberry mojito.
  • Make this refreshing blackberry iced tea
  • Use it as a liquid sweetener in homemade blackberry lemonade
  • Serve over vanilla ice cream or plain yogurt
  • Drizzle over pancakes instead of maple syrup

​How to Store Blackberry Syrup

Blackberry syrup will stay good in the refrigerator for a week or more. Store it in a mason jar and use it throughout the week in your favorite beverages. 

For longer-term storage, you can freeze this blackberry syrup. I recommend putting single servings in ice cube trays and freezing them for a few hours. Once the ice cubes are completely frozen, remove them from the trays and store them in an airtight container, such as a plastic bag or a jar. When making a beverage, take a frozen cube out and allow it to thaw for 30-60 minutes before using it.
