Blueberries - can be fresh or frozenwild blueberries are preferred
Batch of kombucha that has completed primary fermentation
Instructions
Chop up the ginger root into smaller ginger pieces, leaving the skin on.
Wash out your glass bottles with hot water, making sure they're clean.
Place a few pieces of ginger and about about 1tbs of blueberries into each bottle.
Fill to the top with first fermentation kombucha tea, naming sure to go all the way to the brim.
Seal and set out of direct sunlight at room temperature, for 3-7 days for secondary fermentation.
Check every few days. When carbonation builds up, release a little bit to avoid explosions.
Taste check to see if the kombucha has reached your desired flavor & carbonation level. Serve over ice.
Notes
How long does it take to make ginger blueberry kombucha?
The process typically takes about 7-14 days for the first fermentation and an additional 3-7 days for the second fermentation, where the flavors develop.
What type of tea should I use for kombucha?
Use organic black tea, organic green tea, or decaf/herbal tea. Avoid teas with added oils or artificial flavors as they can harm the SCOBY.
Can I use frozen blueberries instead of fresh?
Yes, frozen blueberries can be used. Thaw them first to help release their juices and blend better with the kombucha.
How much ginger and blueberries should I add?
For a 1-quart (1-liter) bottle, add about 1-2 tablespoons of grated ginger and 1/4 to 1/2 cup of blueberries. Adjust to taste.
How do I ensure my kombucha is fizzy?
Ensure your bottles are tightly sealed during the second fermentation and that they are filled all the way to the top. For more tips, see my kombucha brewing Ebook!
What if my kombucha is too sour?
Shorten the fermentation time or add more sweetener during the second fermentation to balance the flavors.
How do I store ginger blueberry kombucha?
After the second fermentation, store the kombucha in the refrigerator to slow down the fermentation process and preserve its flavor. Consume within 1-2 weeks for the best taste.
