That's ... priceless."Mine!"
Why I roast my own coffee. These little beans are filled with holes that mold has grown in. How this happens, well flies lay their eggs on the flowers. They hatch once the fruit grows and the worm tunnels through the seed and leaves it open for moisture to get in that allows the mold to grow.
No, this does not add to the flavor. This is what would turn a perfect cup of coffee rancid, bitter, mud like, sour cherry. A cup of nasty. The cup you just want to throw out the door and scream at someone.
With that said. Time for some coffee!
