[Homeroast] Start of exothermic reaction

On Facebook I saw a post,
"Fun coffee fact: First crack of coffee is endothermic, i.e., the
reaction takes external heat energy. But second crack is exothermic:
The beans start generating their own heat."
And thought, "no, first crack is exothermic too." Then I went online
to verify. But it seems exothemeric reactions start even earlier.
One source states it is occurring when the internal bean temp gets to 375F.
Of course, sources are not consistent.
What's the consensus here about the start of exothermic phase?
