Squeeze orange juice and add about 3 cups to each mason jar.
Prepare vegetable starter culture per package directions.
Add about ½ cup of filtered water and 2-3 tablespoons of culture starter to each jar of orange juice and whisk to combine.
Screw the lid on the jar, then set it somewhere warm yet out of sunlight.
Let the jar sit at room temperature for 24-48 hours until it’s bubbly. You may need to burp the jar to prevent too much pressure from building up.
Once it’s bubbly, refrigerate and serve!
Notes
Please note: Nutrition information is for orange juice before being fermented. Since the fermentation process consumes the sugar, sugar content after fermentation may vary.
