Elderflower Kombucha

Elderflower kombucha tastes just like elderflower cordial and is one of my favorite second ferments. Second fermenting your kombucha is a great way to recreate your favorite pop without the junk. It makes the kombucha more bubbly and even more delicious!

At the start of the summer I fancied something sweet and refreshing and since I had a black elderberry tree growing just outside the house I decided to try elderflower kombucha.

The result tasted just like elderflower cordial – not everybody’s cup of tea but I love it!

If you’re living anywhere with a few trees around, chances are that there’ll be some black elderberry trees among them.

There’s certainly plenty around where I life. Both the flowers and the berries are commonly used to make syrups, cordial and wine.

All parts of the tree have traditionally been used to treat various immune related ailments.

All parts of the tree contain strong immune-stimulating and anti-viral properties.

In spring and summer the tree will carry clusters of elderflower which are sweet in taste. In late summer these will turn into the dark purple berries.

Elderflower has long been used to make cordial but the cordials sold in the supermarkets these days are laden with sugar and not very healthy.

My elderflower kombucha tastes just like sparkly elderflower cordial and is full of probiotics and nutrients.

On top of that it’s sweet, refreshing and delicious! It is the perfect summer drink and a great replacement for sugar-laden pop.

Second fermenting kombucha works by adding fruit, spices, honey or other ingredients to the ready brewed kombucha and thus providing more food for the microbes in the kombucha.

This will create more carbonation and nutrients.

Clip top bottles are ideal to use for the second ferment as they can stand the pressure created by the carbonation.

The kombucha is then left to ferment for another 4 days.

After that you can filter the flowers out and transfer the bottle to the fridge. You could also just leave them in.

The kombucha will become more sour the longer you leave it in the fridge but it will last for ages. You can read everything about kombucha here…
