Does anyone know how many ppm 1 gram of Potassium carbonate will add to 1 gallon? I read Ken Schramm's article is Zymurgy about adding it to assist with buffering acid, but he didn't give amounts to add. Does anyone have suggestions for this?Thanks!

I just found the answer to my own questionAdding 5g of K2CO3 to a 5 gal batch of mead adds ~136 ppm ofsupplemental potassium, while the carbonate serves to temper thecharacteristically low honey pH and the normal pH drop created by thefermentation process.This is thanks to High Test's FAQ on the subject. (I hope you don't mind me pasting it here.) Thanks again for all your valuable info and research High Test!
