Dr. Joseph John, co-founder of Josuma Coffee Company and an advocate for Indian-grown coffee in the United States, died Sept. 15 at 88. He developed the Malabar Gold Espresso blend, taught about espresso science and helped build connections between Indian producers and U.S. specialty roasters.
Dr. Joseph John, the former nuclear physicist who helped introduce Indian-grown coffee to U.S. specialty roasters and developed Josuma Coffee Company’s Malabar Gold Espresso, died Sept. 15 at age 88, according to Daily Coffee News. Known in the coffee industry as Dr. John, he co-founded the company with his wife, Urmila, in 1992 and became an educator and advocate for Indian coffee and espresso.
John and Urmila established Josuma Coffee Company in the San Francisco Bay Area to connect U.S. buyers with Indian estates and coffees that could meet specialty-roaster quality requirements. At the time, Indian coffee was largely overlooked in the U.S. specialty market, according to Daily Coffee News. John also worked with growers and the Coffee Board of India to improve quality and raise the origin’s profile with American buyers.
In 1996, John created Malabar Gold Espresso as a demonstration of what Indian beans could contribute to premium espresso blends. The blend, made exclusively with Indian coffees, later became Josuma’s flagship roasted coffee. John also argued for the use of high-quality robusta in espresso blends, challenging preferences common in the American specialty coffee industry.
From the early 2000s, John taught and wrote about espresso extraction and blending, including at Coffee Fest and other industry events. His work included a two-part article on espresso blending published in Roast magazine in 2008 and the 2023 book Creating a Perfect Espresso. He retired in 2017, but remained involved in coffee education. Josuma became an early supporter of the UC Davis Coffee Center in 2018. The company remains family-owned and is managed by John’s son, Melind, and daughter-in-law, Steph.
How John Changed Indian Coffee’s Reach
John’s work linked Indian coffee producers with American specialty roasters at a time when the origin had limited visibility in that market. His approach combined sourcing relationships with efforts to improve quality, giving U.S. buyers a route to Indian coffees that met specialty standards. The impact is reflected in both Josuma’s continued operation and the company’s role in building relationships across the supply chain.
His influence also extended to how roasters thought about espresso. Through Malabar Gold, teaching and published work, John made the case for blending Indian coffees—including robusta—into premium espresso. That contribution matters to coffee professionals and consumers because it broadened the discussion of which origins and bean varieties could have a place in specialty espresso. The source material describes his role and influence, but does not quantify the scale of changes in U.S. coffee buying or consumption.

From Nuclear Physics to Coffee
Born in Madurai, Tamil Nadu, in 1938, John earned bachelor’s and master’s degrees in physics before joining India’s atomic energy program in 1958, at age 20. He moved to the United States in 1964 and earned a doctorate in nuclear physics from Florida State University in 1968. He later worked for Gulf General Atomic, a predecessor of General Atomics, in San Diego, then moved into business and consulting in the Bay Area.
His coffee career began after an acquaintance connected to an Indian coffee estate asked him to help find American buyers. In a 2012 interview with Fresh Cup magazine, John said he and Urmila had not planned to enter the coffee business: “It was not by design. It was really just sheer accident.” They founded Josuma in 1992 and built its work around Indian estates and specialty-market buyers.
Barth Anderson, co-founder of Barrington Coffee Roasting Company, credited John with introducing him to Indian specialty coffee in 1996, according to a 2018 account of Indian coffee’s development. John’s teaching later brought that expertise to industry audiences through classes such as “Espresso and Coffee: More Different Than You Think.”
