Why Coffee Makes You Do Your Business

James Hoffmann, the author of

The World Atlas of Coffee and the creator of a coffee-centric YouTube channel, can tell you many things about coffee—from how to roast coffee, to the tools and techniques needed to make espresso, to the ultimate French Press technique. Then he can also get into more tangentially related questions, like why coffee makes you drop the proverbial deuce. Above, Mr. Hoffmann takes you on a short scientific journey through the human body, exploring the effects of coffee on digestion, gut bacteria, and our nervous system. We’ll provide no spoilers or gory details here.
