Here are some nice charts from the Colombia Coffee Hub that show 14 possible green coffee defects. They include brief summaries of what causes them and how they affect roasted coffee. I almost find it hard to look at—like photos of STDs in a science text book—the sad little leprous beans that will never make a happy cup of coffee. But we must not avert our gaze, but show compassion for the process, and learn from them.
If you haven’t signed up for the Colombia Coffee Hub yet, there’s a lot of nice articles worth reading. It’s also a really cool site, but a bit lonely right now.
