When Is Kombucha Ready to Drink or Bottle?
The honest answer: when it tastes done to you. Here's how to develop that judgment fast — and why pH strips can't make this call for you.

- Start tasting around day 5–6 (day 7 once you know your rhythm).
- You're listening for a pleasant acidic ting that isn't overpowering.
- Too sweet? Wait longer. Too tart? Bottle now with sweeter flavorings.
- pH measures acidity, not doneness — taste is the only real gauge.
The taste test
Slide a straw past the SCOBY, cover the top with your finger, and pull a sip (Ange prefers a wine thief, mostly for the joy of announcing "there's a thief in the house!"). Skip tasting in the first few days — it'll just taste like sweet tea, and that's prime SCOBY-forming time anyway.
Day by day, sweetness falls and tartness rises. Where you stop is pure preference: bottle early for a sweeter, gentler brew; let it ride for something drier and more assertive. Both are correct. There is no single right way.
Reading the signals
| What you taste | What it means | What to do |
|---|---|---|
| Sweet tea, barely tangy | Fermentation is young | Wait 2–3 more days, taste again |
| Pleasantly tart, a little sweet | The classic bottling window | Flavor & bottle it |
| Sour, vinegar-forward | Went long — still totally usable | Bottle with sweeter fruit, or bank it as strong starter tea |
Why pH strips can't tell you
pH tells you the brew is acidifying safely — useful as a health check — but it doesn't measure sugar, flavor or balance. Two brews at the same pH can taste wildly different. Use pH if you enjoy the data (Ange has a whole video on kombucha & pH); use your palate to decide when to bottle.
After just 4–5 days, kombucha is already drinkable and already full of the good stuff — it's just sweeter than most people prefer. There's no "unsafe middle" you need to wait through.
