I have been a coffee geek since I started home roasting more than a decade ago. Since then, coffee has taken me on countless adventures: From ancient coffee ceremonies in Ethiopia to the volcanos of Sumatra.
My background is in journalism, and today I'm also a licensed Q Grader under the Coffee Quality Institute.
