Region: Mount Kerinci, Jambi Province, Indonesia

Altitude: 1200–1600 meters

Grade: G1

Varietal: Catura / Lini-S

• Catura contributes brighter acidity and clear fruit-forward notes, often resulting in a clean, lively, and layered flavor profile. Lini-S, a common Indonesian varietal adapted to local high-altitude and volcanic soil environments, typically provides a soft sweetness and balanced mouthfeel. The combination of these two results in a coffee that offers bright acidity, delicate aromatics, and a rounded sweetness, showcasing the fresh and modern specialty coffee style of the Mount Kerinci region.
• Mount Kerinci is located in the west-central part of Sumatra, Indonesia, within Jambi Province, and is one of the few high-altitude specialty coffee regions in the country. Surrounded by the Kerinci Seblat National Park, the area boasts a pristine ecological environment with rich biodiversity. Coffee is grown at altitudes ranging from 1200 to 1600 meters in fertile volcanic soil. Favorable sunlight, rainfall, and significant diurnal temperature variations allow the coffee cherries to ripen slowly, accumulating higher sweetness and more complex aromatic compounds.
• Unlike traditional Sumatran coffees, which are largely processed using the wet-hulled method, the Mount Kerinci region has recently developed washing, natural, and various experimental fermentation processes, resulting in a cleaner, brighter, and more layered flavor profile. Compared to the heavy body and herbal notes of classic Mandheling, this region’s coffee leans more towards floral, fruity, and crisp acidic profiles, aligning closely with modern specialty coffee standards and offering excellent distinctiveness and appeal.

Process: Lactic Fermentation Natural

• Lactic fermentation natural processing begins with the careful selection of high-quality, ripe coffee cherries. After hand-sorting and screening, the cherries are placed in a controlled environment for fermentation. During this process, lactic acid bacteria convert sugars, resulting in a softer, more rounded acidity while enhancing the sweetness and the delicacy of the fermentation aromatics.
• Once lactic fermentation is complete, the cherries are dried using the natural (sun-dried) method. During drying, the fruit pulp and mucilage remain in contact with the coffee bean, allowing the sugars and aromatic compounds to slowly permeate the green bean, resulting in a fuller fruit sweetness and richer aromatic complexity in the cup. Compared to traditional natural processing, lactic fermentation natural usually yields a cleaner fermented character, softer acidity, and unique flavor notes reminiscent of yogurt, soda, and sake.
• In summary, this Indonesian Mount Kerinci "Blue Bell" lactic fermentation natural is vibrant, with fresh aromas and a lively mouthfeel. From the bright floral and tropical fruit sweetness at the start, to the yogurt-like lactic texture and effervescence in the middle, and finally to the sake-like fermented finish with its clean, lingering sweetness, the layers are distinct and well-defined. It is well-suited for drinkers who appreciate floral and fruity notes, refreshing acidity, unique fermentation profiles, and highly distinctive coffee.
