More information: pH testing is not a requirement for Kombucha brewing. In fact, most home brewers do not test the pH level of their batches. However, we do recommend pH testing if a person wishes to deviate from a standard recipe (e.g., use less sugar, use a tea other than black or green tea, etc.) or has a batch that appears to be culturing abnormally. Ultimately we recommend using good judgment and adhering to a standard recipe when brewing Kombucha Tea. If in doubt, test the pH level and never consume Kombucha Tea that looks, smells, or tastes unpleasant.

Product Q&A

Q. How do you exactly use the test strip to measure the ph of Kombucha tea?

A. Simply dip the end of the strip that has the tiny paper pad into a sample of your kombucha for 1-2 seconds. In 10-15 seconds the strip will change color. Hold the small square up to the enclosed color chart to determine the pH. Kombucha is ready when it registers at 4.0 or lower.
