What’s the best thing to do with a large batch of blueberries you’ve picked from your garden?

For me, it’s to make homemade blueberry syrup for coffee! The syrup is easy to make, and you can use it immediately or store it in the refrigerator.

If you want to add a new twist to your favorite coffee drinks, this blueberry syrup recipe is a great place to start!

What is blueberry syrup?

Blueberry syrup is an easy homemade recipe that you can make in minutes. It’s made using white granulated sugar, blueberries, and a touch of water.

Blueberry syrup is made by boiling blueberries with sugar and then letting them cool down enough to be poured into reusable containers, like a Mason jar or a nice flask with a pouring spout.

Tip: You can also use this mason jar to brew cold brew! Check out this recipe here.

Blueberry syrup tastes better than ever because of the smaller amount of sugar and added flavorings.

The flavor you get when using sweet blueberries in season is fantastic and can’t be compared to a store-bought version.

Which ingredients are used to make blueberry syrup for coffee?

Coffee syrups shouldn’t be hard to make, which is why this recipe for blueberry syrup uses just a few ingredients. Have a look below for all the ingredients:

  • Blueberries
  • White granulated sugar
  • Cold tap water
All ingredients that are used to make blueberry syrup at home.

Those three ingredients will make a sweet and delicious add-in to your favorite coffee.

White granulated sugar is the best to use, as it has a fine structure. Because of the fine structure, the sugar will dissolve much quicker, which is perfect for this quick recipe.

The recipe is based on the classic 1:1 ratio of sugar and water used to make simple syrup.

When adding blueberries to this, you’ll make it even sweeter, and it’ll leave a striking blue color.

What kind of blueberries can you use?

Blueberries have an amazing sweetness and many flavors but not much tartness, making them perfect for this syrup.

You can use fresh or frozen blueberries to make the syrup at home.

I prefer using fresh blueberries when they’re in season. When the blueberries are in season, they’ll taste much sweeter.

The only downside to fresh blueberries is that they might be more expensive.

When using frozen blueberries, which (in most cases) is the cheaper option, make sure to defrost them beforehand.

I like to get a cup of blueberries from the freezer right before bed so they’re defrosted the following day.

To make the best blueberry syrup for coffee, make sure to taste the blueberries before adding the other ingredients.

Fresh blueberries are usually a bit sweeter, so you might want to leave out some sugar.

The frozen blueberries tend to be a bit sourer, so you might want to add a bit more sugar to the mixture, depending on your flavor preference.

When you still find that it needs a bit of sugar after making the blueberry syrup, you can add some more to it and place it back on the stove.

Keep making adjustments until you’ve reached the perfect blueberry syrup for your taste!

Blueberry Syrup for Coffee

Homemade blueberry syrup.

Making blueberry syrup is easy to do and will make your coffee have a unique flavor profile.

Prep Time 3 minutes
Cook Time 5 minutes
Additional Time 2 minutes
Total Time 10 minutes


  • 1 cup (250 grams) of white granulated sugar
  • 1 cup (250 grams) of cold tap water
  • 1 cup (250 grams) fresh or frozen blueberries


Before beginning with the recipe, I like to collect all the ingredients. After that, it's time to jump into the recipe:

  1. In a small saucepan, combine the white granulated sugar, cold tap water, and blueberries.
  2. Place the small saucepan on the stove on medium heat.
  3. While continually stirring, heat the mixture.
  4. Lower the heat once the sugar has dissolved completely and the blueberries have gone a bit soft.
  5. Leave the mixture to bubble away for a few more minutes, so the berries are nice and soft.
  6. After the blueberries are super soft and the sugar has dissolved, remove the saucepan from the heat.
  7. To make the blueberry syrup smooth, place a handheld mixer into the saucepan until the blueberries are super fine.
  8. You can also add the mixture to a blender.
  9. If, after blending, the blueberry syrup still has pieces of blueberry in it, you can sieve it until smooth.
  10. Transfer the smooth blueberry syrup into a resealable container or flask of choice and store in the fridge until use.


When using frozen blueberries, makes sure to defrost them before adding them to the saucepan.

How long can you store blueberry coffee syrup?

When making blueberry syrup at home, storing it in a resealable jar for optimal storage is best.

It’ll last much longer in your fridge before going bad. I like to place it in the coldest place in the refrigerator to ensure it stays as cool as possible.

Because lots of sugar is used, you can keep it in the fridge for a long time. I recommend sticking to a one-week maximum.

If you’re unsure if you’ll finish a batch by then, you can also make a smaller batch.

Then, after you’ve almost finished that small batch, you can make some more and keep this going until you’re out of blueberries.

It’s a great way to ensure you’re using the freshest blueberry syrup, and it’ll also taste the best.
