This syrup is very versatile. We’ve used it to pump up the flavor of many of our favorite beverages. It’s amazing in lemonade and iced tea. But at our house, the main purpose of this blackberry simple syrup is cocktails.

Making blackberry simple syrup, or any type of berry syrup, is quite easy. It involves only three ingredients: berries, water, and sugar.

The outcome is this beautiful deep purple liquid that is like liquid sunshine. The blackberry flavor is so concentrated, and the color is gorgeous.

How Much Sugar to Use

My main gripe about simple syrup is just how much sugar goes into it. A lot of recipes call for the same amount of blackberries as sugar. That’s something like one cup of blackberries to one cup of sugar. Um… that’s a LOT of sugar. The syrup will be really super sweet if you use that ratio.

So, I always recommend half that amount of sugar. Doing it this way will ensure you’re getting lots of blackberry flavor, but your teeth aren’t falling out due to sugar overload.

If you want it to be super sweet – to adequately sweeten homemade blackberry lemonade, for instance – you may need to increase the sugar. Start with half a cup and add more, if you find it necessary.

Don’t fret if you’re on a low-sugar diet. You can substitute the sugar with allulose, erythritol, or swerve. I make it with allulose when I’m on a keto diet. That’s the best substitute for me because it’s a 1:1 replacement for sugar. Erythritol and Swerve both have their own “sweetness level” so you’ll have to experiment with how much to put in.

Steps to Make Blackberry Simple Syrup

Step 1

blackberries and sugar water

Put the blackberries, water and sugar into a small saucepan over medium heat. Bring it to a boil.

As the liquid heats and boils, the blackberries will pop and the liquid will become darker from the pigment in the skins of the berries. Let it simmer at a low boil for about 15 minutes. It should be really dark and slightly reduced.

Step 2

Pour the contents of the saucepan slowly into a fine mesh strainer to separate the liquid from the solids.

Use the back of a spoon to press the liquid gently through the skins. You can use the remaining skin and pulp for something else, if you want.

Step 3

Now that you have just liquid, allow it to cool down completely, then you can chill it in the refrigerator. It should always be thoroughly chilled before using.

Storing Blackberry Simple Syrup

This recipe makes about 8 servings of 1 ounce each. It’s unlikely you’ll be using that much all at once, unless it’s for a party or a large pitcher of lemonade. So it’s pretty common to have some left over.

That’s fine because this syrup can be kept for up to a week in the refrigerator it in an airtight container. Then you can get it out whenever you want to add some to a drink.

The best drinks to use it for are Blackberry Gin & Tonic, Blackberry & Basil Margaritas, or a simple Blackberry Spritz. You can also use it for a pitcher of Blackberry Lemonade.
