About Marcus Thorne
I came to coffee sideways—through years of lab work that taught me to question everything and measure twice. When I burned out on that career, I realized I'd already been applying the same rigor to my morning brew. Now I spend my time understanding exactly why a cup tastes the way it does. I've tested more variables than I care to admit, competed in brewing competitions, and consulted for roasters who wanted to geek out on extraction science. My partner David has banned experiments from our kitchen after one too many "incidents," and our cat Erlenmeyer judges me from atop the espresso machine. I write because I believe understanding the why makes you a better brewer. Not to create more coffee nerds like me—but to help you troubleshoot, experiment, and find what works for your cup. The science is fascinating, but the goal is always a better morning. Based in the Pacific Northwest. Probably recalibrating something right now.
