Two ingredients, and both of them have a right answer that is cheaper than the wrong one.
By Scooter M.·Published September 1, 2026
The short answer
True tea from Camellia sinensis — black, green, white or oolong — and plain white granulated cane sugar. Herbal infusions are not tea and do not feed the culture. Avoid heavily oiled flavored teas — bergamot blends above all — for repeated batches, because the oils accumulate on the culture.
| Tea | Works? | Notes |
|---|---|---|
| Black | Yes — the default | Most nutrients for the culture, most robust flavor. |
| Green | Yes | Lighter and faster. Slightly less to feed on than black. |
| Oolong | Yes | Between the two. The Kombucha Shop ships a black and oolong blend. |
| White | Yes | Very delicate. Best blended with black rather than used alone. |
| Bergamot blends and other oiled teas | Occasionally | Added oils accumulate on the culture over repeated batches. |
| Herbal infusion — rooibos, chamomile, mint | No | Not tea. Does not contain what the culture needs. |
| Decaffeinated tea | Poorly | Decaffeination strips more than caffeine. Cultures decline on it. |
The reason herbal infusions fail is straightforward: kombucha cultures are adapted to compounds present in Camellia sinensis, and a chamomile infusion is a completely different plant with a different chemistry. It is not a matter of strength or steeping time.
Black tea gives the culture the most to work with and produces the most robust result. Green tea produces a lighter, brighter drink and ferments a little faster. A blend gets both, which is why several kits ship one — The Kombucha Shop publishes organic loose leaf black and oolong in its kit contents.
A common working ratio is two-thirds black to one-third green. There is nothing precise about it; adjust to taste and watch the culture, which will tell you over a few batches whether it is thriving.
The culture eats the sugar. That is the whole role, and it is why substitutions do not work the way people hope.
Useful for a first batch precisely because they remove the variable. After that, plain supermarket tea and sugar cost a fraction of a kit sachet and work identically.

One cup of sugar and eight tea bags — or about two tablespoons of loose tea — to roughly fourteen cups of water. Steep the tea in about four cups of just-boiled water for ten to fifteen minutes, remove it, dissolve the sugar into the hot tea, then top up with cold water.
Dissolving the sugar while the tea is hot matters. Sugar that has not dissolved sits at the bottom of the jar unavailable to the culture, and it is a surprisingly common reason a batch ferments more slowly than expected.
Chlorine and chloramine are added to municipal water to suppress microbial life, which is precisely what a kombucha culture is. Filtered water is the simplest answer. Tap water left standing uncovered overnight loses free chlorine, though not chloramine, which many utilities now use instead.
If a culture is persistently sluggish and the temperature is fine, the water is the next thing to change. The same applies more sharply to water kefir, where Cultures for Health specifies unchlorinated, unfluoridated water outright.

#1 · The most measured starter tea
Twelve fluid ounces of mature starter tea with the pellicle, measured against the maker’s own published ten percent rule — the fullest kit of the group.
Who it is for. Someone who wants the culture to be the strongest part of the kit rather than the jar.

Skip it if. You want to bottle at the end of week one. Nothing here holds pressure; budget for swing-top bottles at the same time.

#2 · A first batch with nothing missing
The only kit here that ships pH strips, a pipette and a temperature gauge in the box, which is the difference between brewing kombucha and guessing at it.
Who it is for. Someone brewing their first batch who wants the measurement gear included rather than ordered separately three days in.

Skip it if. You already own a gallon jar. You are paying for glass you have, and a culture-plus-ingredients pack costs far less.
