This is a difficult question to answer, but I can try to explore some possibilities.  In a way, I'm glad you asked.  I wanted to ask you about something similar, and I'm glad you raised this question first.

First I'll try to understand your heartburn question.  Do you mean, why does coffee typically cause heartburn for some people?  Or, what is the mechanism for the heartburn?  Or maybe, why do some people feel heartburn from coffee, but not others?
