What Is DIY Ginger Kombucha & Ginger Bug Fermentation?
What Is a Ginger Bug?
A ginger bug is a wild fermentation starter made from fresh ginger, sugar, and water. It’s naturally rich in wild yeasts and beneficial bacteria. Once fermented, it acts like a probiotic-rich culture similar to a kombucha SCOBY, and is used to carbonate beverages.
What Is Ginger Kombucha?
Ginger kombucha is a tangy, fermented tea drink made by fermenting sweetened tea with a SCOBY, and optionally flavored or carbonated with a ginger bug. It combines the health benefits of kombucha with the anti-inflammatory powers of ginger.
Health Benefits of Ginger Kombucha
- Improved digestion from live probiotics
- Boosted immunity from gingerol and antioxidants
- Better nutrient absorption and energy support from B-vitamins
- Liver detoxification support through glucuronic acid in kombucha
- Low-sugar natural soda alternative without artificial additives

How to Make a Ginger Bug Starter
Step-by-Step Instructions
Day 1:
- Add water to a sanitized glass jar.
- Stir in grated ginger and sugar.
- Cover with cloth and secure with rubber band.
- Let it rest at room temperature.
Days 2–5:
- Feed the bug daily: 1 tablespoon each of sugar and grated ginger.

How to Brew Homemade Ginger Kombucha
Step 1: Brew the Sweet Tea
- Bring 4 cups of filtered water to a boil.
- Add tea bags and steep for 10 minutes.
- Stir in sugar until dissolved.
- Add remaining 4 cups cold filtered water to cool the mixture.
Step 2: Add SCOBY and Starter

- Cover the jar with a cloth or coffee filter.
Step 3: First Fermentation
- Let ferment at room temperature (68–75°F) for 7 to 10 days.
- Taste after day 7. It should be slightly tart, not overly sweet.
Step 4: Flavor with Ginger Bug (Second Fermentation)
- Remove the SCOBY and save 1 cup kombucha as your next starter.
- Pour kombucha into bottles, leaving 1–2 inches of headspace.
- Add 1–2 tablespoons of ginger bug to each bottle.
- Seal tightly and ferment at room temperature for 2–4 days.
- Refrigerate once carbonated.
Tip: Always burp your bottles daily to avoid overpressurization.
Tips for a Successful Ferment
