Kombucha pH Test Strips

When the pH of Kombucha drops below 4.0 then it is safe to drink as no other microorganisms can survive, but 3.5 is generally considered a good pH for a finished brew. Still, the strips do not indicate that your brew is ready, only that it is protected and brewing safely. Taste will indicate if the brew is complete.

These work great! Would highly recommend if you are new to making Kombucha and need that extra certainty to make sure your kombucha is safe to drink. The strips were ordered with water kefir grains. They originally only sent the water Kefir, but as soon as I contacted them, they replied immediately and in addition sent some extra strips as an apology for the mistake. Great costumer service!

I found these test strips to be very helpful when I was just starting out as a new brewer. These strips really helped me train my taftebuds to know what my Kombucha should taste like at its various ph levels. These strips were very easy to use. Highly recommend purchasing them especially if you’re new to brewing.

As an impatient new brewer, these strips are helping me to figure out when my brew is done. It helps me see that I'm getting close and I have a SCOBY hotel and it helps me know when I've made kombucha vinegar too. They are easy to read and use. I've been happy with everything I've ordered from this company.

I recently purchased pH testing strips from Kombucha Kamp to accurately get the correct pH for my Kombucha which I make in the Continuous Brewing Vessel, also purchased from Kombucha Kamp. I prefer the testing strips over a calibrated meter, as they give me correct instant readings every time. (I also have used the strips to test my saliva and am happy that my body has gone from acidic to alkaline since I started drinking Kombucha and also Kefir, which I also make at home.)

These PH STRIPS are easy to read and very accurate. If you have purchased other brands of the PH strips you know some are difficult to read, inaccurate and expensive. Kombucha Kamp has the best quality of these strips. This company really cares about delivering excellent products and excellent service. I buy only from KK now because they have not once let me down. They really care about their products and customers. Have a question? Within 48 hrs. I get an answer that is always spot on. Thank you KK!
