“As a local time-honored water enterprise with 33 years in the drinking-water industry, we are actively seeking our position and making contributions in Guiyang’s fine-coffee sector, and officially launching the domestically pioneering coffee-specific water—ZERO·The 0th Flavor.” On September 25, at the 2026 Guiyang International Coffee Expo, Guizhou Feilongyu Industrial Group (hereinafter “Feilongyu Group”) released a professional water product developed for specialty-coffee extraction scenarios, filling a gap in the domestic market for affordable fine-coffee-specific water.

It is an industry consensus that 98% of a cup of coffee is water; water quality is the “0th flavor base” determining a coffee’s aroma, sweet-acidity balance, and clean mouthfeel, and a core factor affecting the stability of specialty-coffee output. Relying on its advantage of five local deep rock-spring water sources, Feilongyu Group adheres to natural-source extraction without artificial mineral blending, rigorously benchmarking the SCA international specialty-coffee water standard, and has developed two coffee-specific waters achieving standardized water parameters and refined flavor adaptation, letting coffee beans fully release their authentic flavor.

The two coffee-specific waters precisely cover both professional-store and home-consumption scenarios. The ZERO·RICH full-bodied version uses a 1:2.7 golden calcium-magnesium ratio to lock in coffee sweetness and enhance body, suiting medium-dark roasts and specialty cafés; the ZERO·PURE clear version is compatible with pour-over, espresso, cold brew, and other mainstream extraction methods, highlighting the fruit acidity and floral layers of light roasts, suiting everyday home brewing. Both products use a unified 5L portable format priced at 9.9 yuan; the low-sodium formula solves the industry pain points of salty milk coffee and messy flavor, delivering professional water quality at a popular price.

During the expo, the Feilongyu Group booth offered immersive coffee-tasting experiences throughout; professional baristas brewed live with ZERO·The 0th Flavor coffee-specific water, and the audience directly felt the improvement in coffee flavor through blind comparisons of the same beans and same technique with different water sources.

Industry practitioners present said that in traditional operations, tap water and ordinary bottled water have large quality fluctuations, easily causing unstable store output and difficult flavor standardization. Feilongyu’s coffee-specific water has stable, controllable parameters and excellent commercial adaptability; several specialty-coffee brands reached trial-use and procurement cooperation intentions on-site. Many coffee enthusiasts said that using this specific water effectively improves the thin flavor and prominent off-notes of home-brewed coffee, and the friendly pricing lets ordinary consumers easily achieve a professional-level brewing experience.

“The launch of this coffee-specific water marks a key step in the industrial extension of local water enterprises into the fine-coffee sector,” said Long Zongye, chairman of Feilongyu Group. In the future, the company will continue to popularize the concept of fine-coffee-specific water with specialized, standardized products, leverage Guiyang’s “Coffee City” industry-development advantage, and promote the deep integration and two-way empowerment of the local water industry and the fine-coffee industry, helping upgrade Guiyang’s distinctive consumer industry.
