Picture of pH-Duotest 1,0 - 4,3 roll, 1 m

pH-Duotest 1.0 - 4.3 is an effective way to test the pH of your kombucha. The duotest strips are two-colored, which makes it easier to determine where on the pH-scale the kombucha is located.

To measure the pH, a single drop of the kombucha is dripped onto a small piece of the test paper. After just a few seconds, the pH can be read by comparison with the color scale.

When starting up a new batch of kombucha, make sure the pH of the mixture of tea and the kombucha from last batch (typically mix in the ratio 6:1) is 4.1-4.3. Adjusting the pH downward can be done by adding additional ready-made kombucha or storage vinegar. Adjusting the pH upward is done by adding more sugary tea, as indicated in the instructions for fermentation of kombucha. During the fermentation, the pH will drop below 2 and it is up to the individual's taste to stop the fermentation when the desired acidity is achieved.

A pH-measurement can be done using just 1 cm of the test-paper - giving the possibility to perform 100 measurements with the 1 m roll.

Background

pH is a measure of the concentration of free hydrogen ions (H+) in a liquid.

The pH scale runs from 0 to 14.
pH of pure water is 7.

Liquids having a higher concentration of H+ compared to pure water is an acid and has a pH below 7.
Liquids having a lower concentration of H+ compared to pure water is a base and has a pH higher than 7.

The pH may be of importance to what can or will happen to a liquid.
The pH of a liquid can be changed by adding various chemical substances which then adds or binds H+.

The pH may also change with bacterial activity in a liquid with a content of sugar, like milk or water/tea with added sugar. Here, the bacteria convert the sugar and form lactic acid which increases the concentration of H+. Thus, the pH will drop during bacterial activity.

By measuring the pH during production of, for example, cheese, yogurt, kefir and kombucha you may optimize the result.
