What is the ph Balance of Kombucha and why do I care?
Right, you're going to get mold, you're going to get pathogens, it's not going to be pretty, because the reason why we refrigerate food, or we have it on a chaffing dish warming it up or in a crock pot or something, it's the acidity level that initially helps preserve your Kombucha tea, now there's other things, like the introduction of CO2, which helps you preserve your Kombucha tea, especially when you bottle it, but initially, it's really that PH level.
A good thing to do is, not just test your PH when you go to bottle, or when you go to consume and drink, test that PH when you initially make your Kombucha tea. When you go to bottle, a good PH level would be anywhere from 3.3, 3.4, down to 2.9. Now, getting to the tenths of a degree, like a 3 point something you would probably need to use a more accurate measurement than just those PH strips, something like a PH tester. Once you begin brewing though, you could, I'm not saying this is the best way, but for my own personal consumption, if you're selling Kombucha, you should be testing it, but for your own personal consumption, simply tasting it does it have that bite, reminiscent of apple cider, if it tastes kind of like apple cider, you have a PH of around 3.
Now many people talk about making sure your ph isn't too high when you begin the brewing process. But did you know you don't want it to be too low either? If the ph is too low it could kill of some of the yeasts before they even get a chance to convert the sugar into glucose. This doesn't happen too often… but if you've ever had a batch turn out to be super acidic AND super sweet, this could be your easy fix! You want to shoot for a ph of around 4.5 to 6 when you first start brewing (the lower end would be during winter months as since it will take longer to ferment, the lower ph starting level will provide a nice protection before the fermentation process gets rockin!).
