14 days after roasting, coffee beans have lost over 80% of the aromatic volatile compounds which give it its complex flavor have evaporated, and even $100/lb coffee is no longer ‘specialty coffee’ quality. The answer is buying them green and roasting your own coffee beans. You roast what you need and drink it fresh. And it’s cheap to get started, with no learning curve. Even on a hurried morning, I can wake up with no roasted coffee and still roast, grind and brew a fresh cup by the time I’m ready to sit down to eat.
