Test strips with 1.0 intervals (i.e. 1,2.3) are not precise enough to safely test kombucha. This is because of the importance of your brew’s first ferment starting pH at or below 4.5 and 3.5 on finishing, 1.0 increment strips will not provide this accuracy.
Always use test strips with 0.5 intervals to safely test your home brewed kombucha
