Use Indigo® test strips to show your Kefir fermentation is in the range of pH 3.4-3.6. Your tongue may sense the tart taste but a quick dip of the strip that matches the pH 3.5 color, confirms it's done!
Why kefir? Research indicates it is a beneficial food with many health promoting properties. Further, it is an effective delivery medium for probiotic microorganisms that produce functional organic substances.
Kefir is cow, sheep or goat milk fermented with Lactobacillus kefiranofaciens bacteria & Saccharomyces turicensis yeast. They convert lactose (milk sugar) into lactic acid to produce a slightly acidic, carbonated liquid yoghurt with a pH of 3.4-3.6.
Kefir's exopolysaccaccharides, e.g. kefiran, are fermentation byproducts of probiotic microoganisms such as Lactobacillus kefiranofaciens. The physicochemical properties of this polysaccharide may have antioxidant activities, antibacterial properties, epithelium protection, anti-inflammatory effects & other health benefits.
Non-dairy kefir using almond milk, oat milk, etc. are another way to add kefir's dietary benefits without having to deal with lactose digestion.
You can also compare various dissacharide & polysaccharide chemical structures & note their similarities & differences.
Color chart intervals: 3.0, 3.5, 4.0, 4.5, 5.0, 5.5, 6.0
Intervals of 0.5 pH unit but can resolve 0.25 with practice
Dip strip, shake off excess liquid, compare to color chart immediately
Minimum shelf life is 3 years if kept sealed but 5 years is typical
Store at room temperature away from sunlight.
The number of strips (50) per pack or vial is approximate.

Needed an easy way to check my materials for canning, especially my tomato sauces. These test strips saved me a lot of trouble since I didn't have to add any special acid to them after I discovered that mine were perfect at pH4.0. THis very simple test saved me a lot of money and i'm very happy with the product

Great news & an excellent example of how to use a test strip to make preparing tomato sauce & salsa easier. This old blog might be of some interest to others: How Does Litmus Paper Work? Not Like pH Strips?.
