The Short Version
Former Berkeley National Laboratory researcher Esther Singer is dismantling Indonesian coffee stereotypes by applying biotechnology to the bean. Through Segara Coffee, she treats every cup as a complex ecological puzzle, using scientific rigor to showcase diverse cultivars far beyond the typical earthy Sumatra profile.
Esther Singer spent over a decade researching soil ecosystems and plant-microbe interactions at Lawrence Berkeley National Laboratory before pivoting to biotechnology. When she launched Segara Coffee in Reno, Nevada, in 2025, she didn’t leave her research background behind; she applied it to the complex variables of coffee production. To Singer, the beverage is a massive agricultural puzzle where genetics, climate, and fermentation intersect. You can change one variable and potentially taste the result in the cup.

Challenging the Indonesian Profile
The name Segara—Javanese for “sea” or “ocean”—reflects the vastness of the Indonesian archipelago and Singer’s intention to move beyond narrow market assumptions. For years, many consumers have associated Indonesian coffee exclusively with Sumatra, wet-hulled processing, and heavy, earthy flavors. Singer argues that these categories, while historically significant, often act as limiting definitions that mask the true diversity of the region. This mission is personal: raised between German and Indonesian cultures, Singer found that the coffees available in the U.S. represented only a small slice of Indonesia’s actual landscape. By focusing on cultivars previously unseen in the U.S. and unconventional processing methods, she aims to showcase a much broader spectrum of flavor.
Rather than building a conventional multi-origin portfolio, Segara focuses deeply on a single country to foster long-term relationships with producers. This specialized approach allows Singer to explore how specific environmental factors dictate what ends up in the final brew. She views the industry through an ecological lens, insisting that the conversation must remain tethered to the ground. From her perspective, coffee begins not at the roaster or the cafe, but as a living plant shaped by soil health, labor, and local economics.
The Intersection of Science and Craft
For Singer, success lies in the ability to balance three distinct roles: the scientist analyzing why a bean behaves a certain way, the roaster seeking to express its potential, and the entrepreneur connecting people to nature. Her work is driven by a desire to translate laboratory knowledge into a tangible product that creates human connection. While the technicalities of microbiology and chemistry are central to her process, she acknowledges that the end goal remains purely sensory.
Ultimately, Segara Coffee bridges the gap between complex agricultural systems and the consumer experience. By applying her background in biotechnology and environmental science, Singer treats every cup as a direct expression of the ecosystem that produced it.
Do you think specialty coffee labels like “origin” help consumers understand flavor, or do they create limiting stereotypes?
Questions & Answers
What is the inspiration behind the name Segara Coffee?
The name Segara is derived from the Javanese word for sea or ocean. This name reflects the vastness of the Indonesian archipelago and represents the company's mission to move beyond narrow market assumptions about the region. By using this name, founder Esther Singer highlights her intention to showcase the true diversity of Indonesian coffee. She seeks to expand the consumer's understanding of the country's complex landscape beyond the limited varieties typically found in the United States.
How does Esther Singer apply her scientific background to coffee production?
Esther Singer applies her background in biotechnology and environmental science by treating coffee production as a complex agricultural puzzle involving genetics, climate, and fermentation. She utilizes her previous research experience in soil ecosystems and plant-microbe interactions to analyze how specific environmental variables affect the final brew. By viewing coffee through an ecological lens, she focuses on how soil health and microbiology influence the bean's behavior. This scientific rigor allows her to bridge the gap between complex agricultural systems and the sensory experience.
Why does Segara Coffee focus on a single country rather than multiple origins?
Segara Coffee focuses on a single country to foster deep, long-term relationships with specific producers. This specialized approach allows the company to explore how local environmental factors and specific cultivars dictate the flavor profile of the final cup. Instead of building a conventional multi-origin portfolio, this strategy enables a deeper investigation into the Indonesian landscape. This method helps move beyond historical stereotypes, such as the assumption that Indonesian coffee is exclusively heavy and earthy, by showcasing a much broader spectrum of flavors.
What are the common stereotypes associated with Indonesian coffee?
Indonesian coffee is often narrowly associated with Sumatra, wet-hulled processing, and heavy, earthy flavor profiles. These categories have historically defined how many consumers perceive the region's coffee offerings. However, these traditional definitions can act as limiting labels that mask the actual diversity of the Indonesian archipelago. Segara Coffee aims to challenge these assumptions by introducing unconventional processing methods and cultivars that have previously been unseen in the United States, offering a more comprehensive view of the country's coffee production.
