What's in Blackberry Syrup
- Water - Filtered water will give you the cleanest flavor in this syrup.
- White sugar - Choose cane sugar or beet sugar for the best flavor. If you want to use a different sweetener, try agave nectar, but it will change the flavor of the syrup slightly.
- Blackberries - Fresh or frozen blackberries work great for this recipe. (You can use frozen blackberries straight from the freezer. No need to thaw them first.)
How to Make Blackberry Simple Syrup (Step by Step)
Bring water to a boil in a small saucepan over medium heat.
Add sugar and stir until sugar dissolves.
Add blackberries and cook at a gentle boil for 2-3 minutes or until blackberries are soft.
Remove from heat once the mixture starts to foam and rise up in the pot. (Note - this happens fast! Watch the syrup so it doesn’t boil over and make a sticky mess.)
Using a potato masher or spatula, gently crush the blackberries.
Allow the mixture to cool for at least 10-15 minutes or until it reaches room temperature.
Set a fine mesh strainer over a bowl. Pour blackberry mixture through the sieve.
Using a spatula, gently work all of the liquid through the strainer. Discard the leftover berry pieces.
Pour syrup into a glass, airtight container.
Store in the refrigerator for up to 2 weeks.
Want to Make a Thick Blackberry Syrup?
If you want to use this syrup for pancakes, waffles, french toast, or ice cream, reduce the heat to the lowest setting and continue to cook the syrup for 10-15 extra minutes to further reduce the liquid.
Be sure to stir consistently to help prevent the syrup from bubbling over. Continued cooking will create a thicker syrup that has the consistency of maple syrup. It should coat the back of a spoon.
Recipe Tips
- Let your syrup cool completely in the refrigerator before using it in your drinks. Blackberry syrup should be well chilled when used in cocktails or mocktails.
- Use a glass bottle to store the syrup. Plastic containers can retain the smell of whatever was in them before, so stay away from plastic when you’re going to store syrup for a week or two. It can easily take on the flavor of whatever was previously stored in a plastic container. Glass containers don’t have this issue, making them ideal for storing drink syrups.

I have been blessed this year to (probably due to a lot of rain and sun) to have wild blackberries on our little one acre yard. Over a week I collected 3 cups and made this syrup this evening. Super easy and the house smells like I’ve been making jam all day. Easy one pot recipe with special notes included. So looking forward to trying this syrup in sparkling mineral water.
