I don't know who needs to head this, but the pH of my cold brew #coffee is about 6.14 (before I add cream and sugar)

is that where it needs to be? I have some trouble getting cold brew to turn out. It seems sour in many cases.
I don't know, but my cold brew is delicious according to multiple sources, and even drinking it black I wouldn't say it's sour or bitter.
We get either medium or light roasted beans, which I expect is a big factor, but that's just because we don't like the dark roast (whether brewed hot or cold).
