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 blueberry simple syrup is cocktails.

Making blueberry 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 blueberry 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 blueberries as sugar. That’s something like one cup of blueberries 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 blueberry flavor, but your teeth aren’t falling out due to sugar overload.

If you want it to be super sweet – to adequately sweeten homemade blueberry 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 xylitol, erythritol, or swerve. I’ve make it with xylitol 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 Blueberry Simple Syrup

Step 1

blueberries, sugar and water

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

As the liquid heats and boils, the blueberries 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 it.

Storing Blueberry Simple Syrup

This recipe makes about 16 servings of 1 tablespoon. 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.

How to Use Blueberry Simple Syrup

The main thing we use our blueberry simple syrup for in my house is cocktails. It’s sometime we almost always have in the refrigerator, so we can just add it to any drink we want.

The best drinks to use it for are Blueberry Gin & Tonic, this amazing Blueberry Old Fashioned, or a simple Blueberry Margarita. You can also use it for a pitcher of Blueberry Lemonade.
