Kombucha

Method

• step 1

  For essential information on brewing safely, our top recipe tips and fun flavours to try, read our guide on how to make kombucha. Pour 1.8 litres boiled water into a saucepan, add the teabags and sugar (depending on how sweet you like it or the bitterness of your tea), stir to dissolve the sugar and leave for 6-10 mins to infuse.

• step 2

  Remove and discard the teabags without squeezing them. Leave the tea to cool completely before pouring into a large 2.5- to 3-litre glass jar. Add the scoby and its starter liquid, leaving a minimum of 5cm space at the top of the jar.

• step 3

  Cover the jar with a thin tea towel or muslin cloth so the scoby can 'breathe'. Secure with an elastic band and label the jar with the date and its contents.

• step 4

  Leave to ferment for one to two weeks at room temperature and away from radiators, the oven or direct sunlight. Do not put the jar in a cupboard, as air circulation is important.

• step 5

  After the first week, taste the kombucha daily – the longer you leave it, the more acidic the flavour will become. When ready, pour the kombucha into bottles, making sure to reserve the scoby and 100-200ml of starter fluid for the next batch.

• step 6

  The kombucha is ready to drink immediately, or you can start a ‘secondary fermentation’ by adding flavours such as fruit, herbs and spices to the drawn-off liquid and leaving it bottled for a few more days before drinking. Will keep in the fridge for up to three months.
