Some people have their first cup of coffee in their late teens, maybe early 20s, and some never have coffee at all. Shawn Steiman, who has more than earned his moniker, “Dr. Coffee,” had his first cup at age 10, and he’s still buzzing. Steiman is, without a doubt, one of the most knowledgeable individuals in the field of coffee in Hawai‘i. Trust us, he knows a latte. Born and raised in Kansas City, Missouri, Steiman moved to O‘ahu two decades ago to obtain a master’s degree, and eventually a doctorate, in horticulture from the University of Hawai‘i at Mānoa—and to further pursue his studies of coffee in the only state in the U.S. to grow the crop. Steiman has written multiple books about coffee, republishing one of his first with updated information, “The Hawai‘i Coffee Book: A Gourmet’s Guide from Kona to Kaua‘i” in 2019. And he runs a coffee consulting business, Coffea Consulting.
