5 from 1 reviews

The easiest way to flavor kombucha is with homemade flavor syrups. This flavor syrup recipe has the right mix of sugar to water ratio to make deliciously sparkling kombucha. See the section above for some popular kombucha flavors.


Units Scale
  • 3 1/2 cups water
  • 1 1/4 cups of sugar (or the equivalent in other sweeteners, see notes)
  • Flavors (see notes for options)


  1. Mix the water, sugar, and flavor in a saucepan.
  2. Bring to a boil, then simmer for 5 minutes.
  3. Remove from heat and let stand for 30 minutes.
  4. Strain out the flavoring and store it in a glass jar in the refrigerator for up to two months.
  5. Mix 1 part flavor syrup with 4 parts kombucha tea, then bottle the kombucha and let it ferment for 1 to 3 days to carbonate.
  6. Store the leftover flavor syrup in the fridge for up to 2 weeks or freeze for long-term storage.


  • Feel free to replace the sugar with your favorite alternative sweetener. Non-caloric sweeteners, like stevia or xylitol, can be used to sweeten kombucha instead of sugar. However, they won’t help to feed the yeast, so the resulting beverage may be less fizzy. Honey and maple syrup will help the kombucha carbonate. 
  • The goal in making a flavoring syrup is to make sure that it has a really strong flavor. It’s going to be diluted when it’s mixed with kombucha, so don’t skimp on the flavors.
  • There are lots of different options for this kombucha flavor syrup. Here are some suggestions:
    • 6″ piece of ginger thinly diced
    • 2 vanilla beans split open
    • 2 cups of chopped fresh herbs like mint or lemon balm.
