Q.Coffee grounds pH confusion
I have seen several articles on the web that state that coffee grounds have a nearly neutral pH. However, I then read another article containing comments from a lab that has tested used coffee grounds whose results consistently show a pH of 5.0 or below. Are all the stories about neutral pH anecdotal? Do any of these sources have lab results to confirm their statements? Thanks, in advance, for helping clarify the issue.
