Homemade Blueberry Shrub Recipe

Ever heard of shrub? If you’re already a fan of kombucha and kefir, it’s a must!

A shrub is not merely a syrup! It’s the secret ingredient for making the best cocktails, flavouring your favourite kombuchas, spicing up your desserts, creating fizzy fermented drinks, or even drinking with water…

Easy to make and easy to use, this delicious and extremely fruity syrup can be made in just a few steps as shown here!

What Is Shrub?

A shrub is a maceration of fruit in sweet vinegar. Its name comes from the Arabic word shiraab (which means drink), but this drink can be found all over the world.

Making your own shrub is also one of the best ways to preserve berries. No other preservation method preserves their flavours so well!

Raspberries, strawberries, apricots, blueberries… You can use all your favourite fruit flavours to make your shrub! And even though it’s always better to use freshly harvested fruit, you can also use frozen fruit to enjoy this technique all year long.

  • To flavour kombucha or kefir
  • With fizzy water to create an original lemonade
  • On ice cream

Store at room temperature for one year.

For more subtle flavour combinations, you can add spices or herbs such as rosemary, star anise, nutmeg, or vanilla…

If your shrub is fizzy when bottled, store it in a cool place afterwards to reduce the pressure. Consume quickly, as it contains wild yeast that produce CO2. The pressure will increase with time, even in the fridge.

Making a Fizzy Fermented Drink

To taste your shrub, you can dilute it with plain water and enjoy it as is. But if you want some extra bubbles in your life, add some yeast seeds and let your shrub ferment for 2 to 4 days at room temperature and then in the fridge!

Use our sima recipe as inspiration for the process.

For quantities, we recommend diluting 125ml of shrub for 750ml of water, but if you have a sweet tooth, feel free to test your own dosages!

Easy, quick, fizzy, and above all perfectly thirst-quenching for hot summer days!
