From Zero Flavor, to Coffee Flavor: the “No.0 Flavor” Born for Coffee

The launch opened with a concept trailer, “From Zero Flavor, to Coffee Flavor.” Long Zongye, chairman of Feilongyu Group, then took the stage to elaborate on the product philosophy of ZERO·No.0 Flavor: the so-called “No.0 Flavor” means removing excess off-flavors from the water so it does not compete with the coffee’s own taste, paying tribute to the unique flavor of every cup of coffee with a pure water baseline.

As a local time-honored water enterprise that has been deeply rooted in Guizhou’s drinking-water industry for 33 years, Feilongyu leverages the advantages of five major deep rock-spring sources in the province, adheres to natural-source extraction without artificial mineral blending, and strictly benchmarks against SCA international specialty-coffee water standards. It has refined two product lines—ZERO·RICH (full-bodied) and ZERO·PURE (clear). The full-bodied version uses a golden 1:2.7 calcium-to-magnesium ratio to lock in coffee sweetness and enhance the rounded, full body, suited to medium-dark roast beans and commercial use in specialty cafés. The clear version is compatible with mainstream extraction methods such as pour-over, espresso, and cold brew, precisely highlighting the fruity acidity and floral layers of light-roast beans. Both products share a portable 5-liter format at an accessible price of 9.9 yuan per jug; with sodium content below 10 mg/L and rich natural magnesium, they address industry pain points such as salty milk coffee and cluttered flavors at the root, filling a gap in China’s market for affordable specialty coffee-specific water.

On-site keynote sharing: “Not All Water Is Worthy of Brewing Coffee.”

From the Practitioner’s Perspective: a Great Cup of Coffee Needs Great Water

Lei Ming, vice president of the Guiyang Coffee Industry Association and owner of Blackstone Coffee, drew on years of coffee experience and brewing practice to deliver an on-site keynote. Starting from his hands-on experience in daily brewing and café service, he shared with the audience the importance of good water for presenting coffee’s flavor: the quality of a cup of coffee begins with the choice of water. Lei Ming expressed strong recognition of Feilongyu ZERO·No.0 Flavor Coffee-Specific Water—its clean, clear quality and stable taste better restore the bean’s own flavor when brewing, making it a trustworthy choice of brewing water for both coffee professionals and enthusiasts.

The launch also screened a Wudang District city promotional video. Luo Yun, deputy director of the Wudang District Investment Promotion Bureau, took the stage to present Wudang’s industries, showcasing the district’s business environment and development opportunities for nurturing local enterprises and growing its specialty water and coffee-consumption industries, and extending an invitation to cooperate to the coffee brands and investment institutions present.

On-site Cupping and Free Tasting: Visitors Experience “From Zero Flavor, to Coffee Flavor” Firsthand

After the main-stage program, guests and visitors moved to Feilongyu’s exhibition hall (booth 1T120) brewing experience zone to join the on-site cupping activity. Professional baristas brewed live with ZERO·No.0 Flavor Coffee-Specific Water, and visitors, through blind comparisons of the same beans and same technique with different water sources, directly felt how quality water improves a coffee’s cleanliness, sweetness, and flavor layers. Notably, the on-site tasting won unanimous praise from many coffee professionals, including high recognition from several coffee champions. Long queues formed in front of the booth, and the cupping experience proved hugely popular.

China’s First: a New Coffee-Water Quality Standard Going from Guizhou to the Nation

From its appearance at the coffee expo to the official product launch, Feilongyu’s rollout of China’s first coffee-specific water marks a key step in local water enterprises’ industrial extension into the specialty-coffee track. A company representative said that going forward it will continue to promote the concept of specialty-coffee water through professional, standardized coffee-specific water products, and, leveraging Guiyang’s “Coffee City” industrial advantages, drive the deep integration and mutual empowerment of the local water industry and the specialty-coffee industry, helping upgrade Guizhou’s distinctive consumer industries.
