In a saucepan, bring elderflowers, sugar, and water to a boil.
Reduce heat and simmer partially covered for 10-15 minutes. Let cool.
Place a fine mesh strainer over a jar or bowl and strain the flowers from the simple syrup.
Elderflower Kombucha
Line up 4 (25 ounce) bottles with flip top lids or other air tight bottles.
Using a funnel, pour ½ cup elderflower simple syrup and freshly made homemade kombucha into each 25 ounce bottle leaving 1-2" head space.
Let bottles sit out (at 75° - 85°) for 3-5 days, making sure to pop the lids each day to let out the pressure of the carbon dioxide. Taste each day to test its flavor and fizziness.
Notes
Use freshly made homemade kombucha that has not been refrigerated yet.Refrigerate after the kombucha is done fermenting.
