Coffee Point

BUY WHOLE BEANS AND GRIND THEM AT HOME
Coffee beans, like anything, will begin to break down and become rancid once the inner contents are exposed to oxygen and moisture. To see this process with the naked eye cut open an apple and see what happens. The white flesh starts turning brown pretty fast. This is due to its exposure to oxygen and moisture, the enemies of freshness.

They’re also the enemies of anti-oxidants, those things you hear about that create stability and health in living systems and ward off disease. I’m skeptical about the anti-oxidant health benefits you hear about in coffee. But if it’s true, those anti-oxidants will start to oxidize immediately after grinding, which is OK if you drink the coffee soon after. After a few days however freshly ground coffee doesn’t taste so fresh anymore. And if you get the sugar out, you can start to taste this pretty easily (which is not good for healthier coffee drinking).
