Sparkling Probiotic Elderflower Fizz is a delicious, healthy fermented drink that’s easy to make when elderberries are in full bloom.  It contains many strains of good bacteria that are a treat for your gut.  

The best time to collect elderflowers is on a sunny afternoon when the flowers are fragrant, dry and full of pollen.  I’ve tweaked the ingredients a little but the inspiration for this recipe came from Fermentation (River Cottage Handbook No.18) by Rachel de Thample.


This recipe makes 2 litres of Elderflower Fizz (so just double or triple all the ingredients for more)

  • 12 to 15 large heads of Elderflower (freshly picked)

  • 1 cup Raw Organic Sugar

  • 1/4 cup Water Kefir Grains

  • 4 litres of Water (rainwater or filtered is best)

  • Juice of one Lemon or Lime (optional)


  • 3 litre glass jar or drink dispenser

  • Circle of cotton cloth to cover the top of the jar and a rubber band or tie

  • 2 x 1 litre glass bottles with flip tops for storage


    1. Mix the elderflowers, sugar, kefir grains and water in a large glass jar.

    2. Cover with a fine cotton cloth and secure with a rubber band or tie.  The fabric needs to be fine enough to exclude dust and insects, but still allow access to air.  

    3. Leave at room temperature, out of direct sunlight, for 2 to 4 days.  A nice fizz will develop.

    4. Strain and decant your fermented brew into two 1 litre flip-top, glass bottles.  Make sure you use quality, lead-free bottles that are designed to withstand the frizzy pressure.

    5. Add the juice of a Lemon or Lime (optional).

    6. Keep in fridge until ready to drink.

    7. Enjoy!
