To make the Scoby

If you already have a healthy Scoby, you can skip this section.

Ingredients

• 1.5l filtered water

• 100g golden granulated sugar

• 1 tbsp (6g or 4 bags) black tea

• 250ml raw, unpasteurised kombucha

Method

It’s best to start early in your day to allow time for the tea to cool down. Bring the water to a rolling boil. Turn off the heat and stir in the sugar and tea until the sugar is fully dissolved. Then leave the water to cool down to room temperature (this can take a few hours).

When the tea has cooled down, strain it into a large glass jar and pour in the kombucha. Raw kombucha will usually have its own Scoby sediment in the bottle, so make sure to add it as well to speed up the fermentation. Give it a stir, then cover the jar with a layer of cheesecloth and leave for around 3-4 weeks. At this stage, it’s important to keep an eye on the batch. After 1-2 weeks, a thin layer will begin to form on the surface. This is your Scoby growing. Once that happens, gently twirl the jar or submerge the layer with a spoon every other day to cover its surface with the liquid to avoid any fungus growing. When the Scoby is fully grown it is much more resistant to harmful bacteria.

After around 4 weeks, the Scoby should have established enough for you to lift it out with your hand. It is time to make your own flavoured kombucha.

Ginger & Lemon Kombucha

Ingredients

• 1.5l filtered water

• 100g golden granulated sugar + 1 tsp

• 1 tbsp (6g or 4 bags) black tea

• 30 ml (2 tbsp) lemon juice

• 40g ginger

Method

It’s best to start early in your day to allow time for the tea to cool down. Bring the water to a rolling boil. Turn off the heat and stir in the 100g of sugar and the tea until the sugar is fully dissolved. Then leave the water to cool down to room temperature (this can take a few hours).

Set aside 250 ml of your previous kombucha batch (or the liquid you grew the scoby in) along with the scoby. Make sure to keep the jar containing the rest of the fermented liquid.

To the jug of a small blender, add the lemon juice, ginger and 5 tbsp of water and blend until smooth. Strain the liquid into the jar containing the rest of the fermented liquid along with the remaining sugar. Give it a good stir, then strain it through a funnel into a tall glass bottle with an airtight flip-top, leaving at least 2 cm head room in the bottle. Close the bottle and leave to carbonate for 3-7 days in a dark spot without opening it. Move the bottle to the fridge to stop the fermentation and carbonation. The fermentation speed depends on many things such as the ambient temperature (the warmer = the quicker) as well as the bacteria and yeasts that exist in the bottle.

Careful! We’re only adding liquid to flavour the kombucha. Other recipes will ask you to add pieces of fruit or aromatics like ginger to the bottle, which contain much more natural yeasts and will speed up the fermentation tremendously. If you do that, you need to move the kombucha to the fridge much earlier or you risk the bottle exploding. To be on the safe side, develop a feeling for how your batch ferments by letting the bottle “burp” (opening the flip-top) every other day and thereby checking the carbonation. You can also fill a plastic bottle with the kombucha. Once the bottle feels rock hard, it is ready to be moved to the fridge.

Now use the cooled tea, the leftover kombucha liquid and the Scoby to make another batch of kombucha. Make sure that the tea has cooled down enough or the heat might kill the bacteria. Strain the tea into a large glass jar and pour in the reserved liquid followed by the scoby. Cover the jar with a cheesecloth and leave to ferment for 7 – 10 days. Keep tasting the kombucha after day 7 until it has a pleasant balance of sweetness and tartness. The speed is again dependent on the same factors as above. When the batch is ready, you can continue with step 1.

Homemade Kombucha

Kombucha is quite a wondrous drink. It is naturally sparking, slightly tangy and mildly sweet. You can flavour it with the seasons, from elderflower to Tarocco oranges and use it as a refresher during the sunnier days or the base of a cocktail in front of a crackling fire in winter. If you make it at home, it is virtually bottomless. All it takes is tea, sugar, the flavour of your choice and nature’s most genius ingredient, time, to make a new batch.
