God in a Cup is about Weissmans travels and her shared experiences with the Rockstars of the third wave coffee industry. If you are interested in learning about how third wave coffee developed in the early 2000s and who the founders of counterculture coffee, intelligentsia, and Stumptown led the industry, this book is great at that! Weissman is a complete outsider to the coffee world. I was surprised that while covering the biggest coffee event in the world she hadn't cupped coffee a single time before? Also, it seems that most of her conversations with each founder was about teaching her the very basics of coffee. This book extensively covers different countries and the people in the coffee world, but has an extremely shallow covering terms roasting/brewing/her own personal nuanced insights of the coffee she tasted while traveling.
