Dr. Joseph John, a former nuclear physicist who helped build a U.S. market for Indian specialty coffee, died Sept. 15 at 88. With his wife, Urmila, he founded Josuma Coffee Company in 1992 and developed its Malabar Gold Espresso blend; the family-run company continues under their son and daughter-in-law.
Dr. Joseph John, a former nuclear physicist who helped introduce Indian-grown coffee to the U.S. specialty market and taught widely about espresso, died Sept. 15 at age 88, according to Daily Coffee News. John and his wife, Urmila, founded Josuma Coffee Company in 1992; their work helped bring greater attention to Indian coffees among American roasters.
Known in the coffee trade as Dr. John, he developed Josuma’s Malabar Gold Espresso in 1996, initially to demonstrate how Indian beans could contribute to premium espresso blends. It later became the company’s flagship roasted coffee. John also advocated for high-quality robusta in espresso, challenging prevailing assumptions in the American specialty coffee industry.
John and Urmila built Josuma around relationships with Indian coffee estates and coffees suited to specialty roasters. He also worked with growers and the Coffee Board of India on quality and efforts to expand Indian coffee’s presence in the U.S. market. John retired in 2017, but continued his involvement in coffee education. Josuma remains family-owned and operated under the management of the couple’s son, Melind, and daughter-in-law, Steph.
John was born in 1938 in Madurai, in Tamil Nadu, India. He earned bachelor’s and master’s degrees in physics, joined India’s atomic energy program in 1958, and moved to the United States in 1964. He received a doctorate in nuclear physics from Florida State University in 1968. After working for Gulf General Atomic in San Diego, he moved into business and consulting in the San Francisco Bay Area.
How John Changed Indian Coffee’s Reach
John’s work connected Indian producers with American specialty coffee buyers at a time when, according to the report, the U.S. market largely overlooked the origin. Josuma’s estate relationships and Malabar Gold gave roasters and consumers a visible route to explore Indian coffees, while his work with growers focused on meeting specialty-quality expectations.
His influence extended beyond selling coffee. John became a regular presence at industry events, teaching about espresso extraction and blending and making the case for quality robusta in blends. The passing of a long-standing advocate and educator marks the loss of a voice who linked coffee production in India with U.S. roasting and professional education.

From Nuclear Physics to Espresso
John’s move into coffee was unexpected. An acquaintance connected with an Indian coffee estate asked him to help find American buyers. In a 2012 interview with Fresh Cup magazine, John described the start of the venture: “It was not by design. It was really just sheer accident.” He and Urmila established Josuma in 1992 and focused on direct ties with Indian estates.
John began teaching and writing about espresso in the early 2000s, including lectures at Coffee Fest and other industry events. His classes included “Espresso and Coffee: More Different Than You Think.” He published a two-part article on espresso blending in Roast magazine in 2008 and gathered much of his teaching and writing in the 2023 book Creating a Perfect Espresso. Josuma became an early supporter of the UC Davis Coffee Center in 2018; a conference room there bears the company’s name.
In a 2018 account of Indian coffee’s development, Barth Anderson, co-founder of Barrington Coffee Roasting Company, credited John with introducing him to Indian specialty coffee in 1996. Anderson’s account points to John’s role with both American roasters and producers in India.
