This excerpt is from the Coffee Common book that was distributed at TED2011. The book serves as a brief introduction to coffee that is meant to encourage thought and curiosity among the attendees. We hope it will create a better understanding of the complexities of coffee production throughout the entire process, leading to more conversations and more enlightened consumers.
