Oxidation is not the only thing you need to worry about, what about mold?

Why do you think the higher temperature makes it impossible for the coffee to react with the oxygen in the water?

because oxidation is heat generating reaction, Higher temperature will make it difficult to generate heat, not impossible though. That will slow the process of oxidation. So, coffee can be fresh for longer time. But can the coffee mold in absence of air?
