"Upon grinding, the aroma presents peach, soft caramel, and honeyed sweetness. On the palate, juicy peach leads with crisp apple and star fruit, followed by gentle kiwi brightness and wild rose florals. A smooth caramel note rounds out the cup, giving it a clean, sweet, and very sweet finish."

The Nest x HACHI Coffee Huajing is a collaborative lot produced under the HACHI Project, shaped by a philosophy of controlled experimentation and verifiable quality. HACHI approaches coffee production as a series of observable biological decisions rather than as an inherited routine or loose tradition. Each stage, from cultivar choice to fermentation structure, is treated as a variable that must be understood, managed, and made repeatable. Huajing reflects this disciplined view, with cascade fermentation used to build complexity through sequence and control rather than excess.

This coffee comes from Yundingqing Estate in Shuangjiang County, Lincang, Yunnan, one of China’s developing coffee-growing regions with strong natural potential. The estate sits between 1,450 and 1,600 meters above sea level, where bright sunlight, cooling mountain air, and steady seasonal conditions support slow cherry maturation. The soils are loose, mineral-rich, and organically composed, giving the trees a stable agricultural foundation. Near the Tropic of Cancer, the area benefits from pronounced day-to-night temperature variation, balanced rainfall, and persistent mountain airflows that help preserve plant health and regulate humidity.

Syrina is the variety used for Huajing, bringing a distinctive foundation to this controlled fermentation lot. In this context, the variety serves as the structural base for a process designed to increase aromatic layering while maintaining balance and clarity. Its role is especially important because cascade fermentation depends on the coffee’s ability to carry microbial transformation across multiple stages without losing definition. The resulting expression is guided by both cultivar character and the precision of the production system around it.

After selective harvesting, the cherries enter the first stage of cascade fermentation, where microorganisms begin metabolizing sugars within the mucilage and extracting soluble compounds from the skin and fruit structure. This stage generates a fermentation liquid containing organic acids, alcohols, aromatic precursors, and active microbial populations. In later stages, the metabolically active liquid is not discarded but transferred into a new fermentation cycle with fresh coffee substrate. Because the system already contains adapted microorganisms and nutrients, each subsequent stage begins more quickly and develops through a more complex biochemical pathway.

Through this cascading structure, the fermentation environment evolves continuously from one phase to the next. More microorganisms participate in aromatic compound formation, increasing fragrance intensity, fruit layering, and depth while preserving the cleanliness of the fermentation profile. Huajing, whose name suggests a small path among flowers and a sense of quiet immersion, is designed to express delicacy alongside technical control. The coffee is therefore not defined only by its process, but by the interaction between Yunnan terroir, Syrina variety, and a sequential fermentation system built for precision.
