    pH Test Strips – For Kombucha, Jun, Kefir & Home Fermentation

    A quick and simple way to monitor the acidity of your ferment. These universal pH test strips make it easy to check the approximate pH of kombucha, Jun, water kefir, milk kefir and other fermented drinks at home.

    As fermentation progresses, beneficial bacteria and yeasts produce acids that gradually lower the pH. Testing your brew can help you understand how fermentation is progressing, troubleshoot slow ferments and become more familiar with what is happening inside your jar.

    You Will Receive

    • 80x pH Test Strips with a universal pH 1–14 testing range.
    • Colour Comparison Chart for quick and easy pH readings.
    • Ongoing Support: Personal help whenever you need it — email, chat or phone.

    Why You’ll Love Them

    • Perfect for home fermentation: Ideal for checking kombucha, Jun, water kefir, milk kefir and other fermented drinks.
    • Easy to use: Simply wet the test strip with your ferment and compare the colour with the supplied chart.
    • Fast results: Get an approximate pH reading within seconds.
    • Monitor fermentation: See how the acidity of your brew changes as fermentation progresses.
    • Great for troubleshooting: Helpful when checking whether a slow ferment is beginning to acidify.
    • 80 strips per pack: Plenty for regular testing over many batches.

    How to Use

    • Remove one test strip with clean, dry hands.
    • Place a small amount of your ferment onto the test strip or briefly dip the testing end into a sample.
    • Allow the colour to develop.
    • Compare the strip with the supplied colour chart to determine the approximate pH.
    • Discard the used strip after testing.

    Tip: For the clearest result, place a small sample of your ferment into a clean spoon or container rather than repeatedly dipping test strips directly into your main ferment.

    Understanding pH in Fermentation

    pH is a measure of how acidic or alkaline a liquid is. A lower number means a more acidic ferment, while pH 7 is neutral.

    During fermentation, the pH will generally decrease as bacteria and yeasts convert sugars into organic acids. Tracking this change can be a useful way to see whether your culture is active and how your ferment is progressing.

    Please note: These strips are intended as a simple home fermentation tool and provide an approximate pH reading. pH should be used alongside normal fermentation practices, appearance, aroma and correct preparation rather than as the sole indication that a ferment is safe to consume.

    Frequently Asked Questions

    What can I use these pH strips for?

    They are ideal for home fermentation including kombucha, Jun, water kefir, milk kefir and other fermented drinks. They can also be used for general liquid pH testing.

    What pH range do the strips measure?

    The strips cover a broad pH range from 1 to 14, allowing you to test acidic, neutral and alkaline liquids.

    Why should I test the pH of my kombucha or Jun?

    Testing pH gives you another way to monitor fermentation. As kombucha or Jun ferments, acids are produced and the pH generally falls. Watching this change can help confirm that your brew is acidifying and progressing as expected.

    Can I use them for water kefir?

    Yes. Water kefir becomes progressively more acidic during fermentation, so pH strips can be useful for monitoring how the fermentation is progressing.

    Can I use them for milk kefir?

    Yes. Milk kefir also becomes more acidic as it ferments. The strips can give you an approximate indication of its pH, although the colour and thickness of milk kefir can sometimes make paper-strip readings slightly harder to interpret.

    Are these as accurate as a digital pH meter?

    No. Test strips are designed to provide a quick approximate reading. A calibrated digital pH meter is better if you require highly precise measurements, but strips are inexpensive, convenient and more than adequate for general home fermentation monitoring.

    Can pH tell me when my kombucha is ready?

    It can help, but pH is only one indicator. Fermentation time, temperature, acidity and your preferred taste all play a role. Once your kombucha has fermented sufficiently, taste is usually the best way to decide when it is ready for you.

    Can I reuse a test strip?

    No. Each strip is designed for a single test and should be discarded after use.
