Had a good day yesterday making juice and now have 5 gallons starting to ferment, it would have been quite a bit more but the kids did so much of the work it was only fair to let them drink their fill.
The OG was 1046 which I think is just about OK and I measured the acidity using a H2SO4 wine acidity test kit and I reckon it’s 5.6ppt.
Now the wine info sheet I have says that acidity is upper end OK for white wines and too acidic for reds while my cider book says 3.2 to 3.8 is an OK PH range for cider.
Am I right in thinking that H2SO4 acidity is not really comparable with PH which is measuring something different?
Anyway I’m none the wiser. 3 decades have gone since I did A-Level chemistry and it seems I’ve forgotten far more than I remember.
Does the H2SO4 ppt tell me anything useful for cider?

Re: Apple Juice acidity for cider
Andrew Lea is the man for this. He has a good website, but I have his book to hand...
Nope, he says they're connected but not in a simple way (which we knew), and then only mentions pH

Re: Apple Juice acidity for cider
pH and acidity are only loosely related in my experience.
You need the correct pH to ensure the yeast is happy and the cider doesn't spoil.
You need the correct acidity to ensure it tastes OK!
Second Andrew Lea's book, though nearly all of it is on the website for free!
