Just sitting this morning enjoying my cuppa and Mother Nature's air conditioning before the storms roll in.
It never got below 55o last night, horrible!!!
Seriously, I believe the research has all been based around drip brewed coffee. (All the cancer causing stuff came from the old "percolated" and/or boiled coffee. Those processes caused some nasty changes to some of the chemical structures in the coffee).
I have no idea to your question, but since instant is so highly processed, my guess would be many of the benefits are weakened and/or destroyed.
