How to Make Chai kombucha
Chai kombucha is a warming, spiced version of the traditional fermented tea. To maintain a healthy SCOBY (Symbiotic Culture of Bacteria and Yeast), this method utilizes a clean primary fermentation of black tea, followed by a secondary fermentation where aromatic masala chai spices are infused. This prevents the essential oils in spices like cloves and cinnamon from damaging the delicate microbial culture.

History
This modern fusion combines Indian chai traditions with ancient Chinese kombucha brewing. It emerged from the craft kombucha movement seeking innovative flavor profiles.
Ingredients
- 4 bags (or 1 tbsp loose leaf) Black tea — Unflavored Camellia sinensis; avoid Earl Grey or flavored teas in F1.
- 4 cups (1 quart) Water — Filtered and chlorine-free.
- 1/4 cup Sugar — Organic cane sugar is preferred for SCOBY health.
- 2 tbsp Chai spices (for F2) — Whole cinnamon sticks, cardamom pods, fresh ginger slices, and whole cloves.
- 1 SCOBY — Healthy pellicle with 1 cup of acidic starter liquid.
Equipment
- Large glass jar
- Cloth cover
- Rubber band
- Bottles for 2F
Instructions
Primary Fermentation (F1)
Brew the black tea in 4 cups of water. Dissolve 1/4 cup sugar while hot. Once cooled to room temperature (below 30°C), add the SCOBY and starter liquid to a glass jar. Cover with a breathable cloth.
Time: 7-10 days
Tip: Do not add spices yet. The SCOBY requires a pure tea environment to thrive and avoid contamination from spice oils.
Monitor and Test
After 7 days, begin tasting. The liquid should be tangy and slightly sweet. For safety, use a pH strip to ensure the brew has dropped to between 2.5 and 3.5 pH.
Time: 1-2 days
Tip: A pH below 4.6 is required to inhibit pathogens, but 2.5-3.5 is the ideal range for kombucha.
Flavoring (F2)
Remove the SCOBY and 1 cup of liquid for your next batch. Pour the remaining kombucha into flip-top bottles and add the chai spices (cinnamon, ginger, cardamom, cloves).
Time: 15 min
Tip: Crush cardamom pods slightly to release more flavor.
Carbonation and Infusion
Seal the bottles and leave at room temperature. The residual sugar and spices will infuse while the yeast creates natural carbonation.
Time: 2-4 days
Tip: Burp the bottles daily if you are concerned about pressure buildup.
Fermentation Timeline
- Day 1-3: Start — SCOBY adjusts to spiced tea.
- Day 4-10: Active — Spices meld, tang develops.
- Day 11-14: Ready — Balanced chai-kombucha flavor.
Signs of Success & Spoilage
Good signs
- New cream-colored SCOBY layer forming
- Vinegar-like or tangy aroma
- Visible bubbles/effervescence
- pH level between 2.5 and 3.5
Warning signs
- Fuzzy mold (green, black, or white) on the surface
- Rancid, putrid, or 'rotten egg' odors
- Slimy, dark black SCOBY
- pH remains above 4.5 after 48 hours
Troubleshooting
- Too vinegary
- Cause: Over-fermented Solution: Shorten fermentation time.
Storage
Refrigerate Keeps 2-3 weeks. Add vanilla in 2F for chai latte flavor.
