A San Francisco tech company has turned building wastewater into a craft beer that is now outselling Corona and Stella Artois, according to a recent report. The brewery's product leverages advanced water recycling technology, converting gray water from commercial buildings into a crisp lager. Even skeptics have embraced the brew, which debuted as a niche experiment but quickly gained traction in local markets.
The company behind the beer uses a multi-stage filtration system that includes reverse osmosis and UV treatment to purify wastewater before fermentation. The resulting beverage is indistinguishable from traditional beer, passing blind taste tests. While specific sales figures were not disclosed, the report notes that the beer has surpassed volume sales of both Corona and Stella Artois in select San Francisco venues, a remarkable feat for a newcomer.
This success comes amid growing water scarcity concerns and a broader push for sustainable consumption. The beer's popularity suggests that consumers are willing to accept recycled water products when presented with high-quality, transparent branding. Experts point to similar trends in other sectors, such as recycled clothing and upcycled food, where sustainability credentials drive purchasing decisions.
The breakthrough could accelerate investment in water recycling infrastructure for consumer goods, particularly in drought-prone regions. However, scaling the technology remains challenging, as current systems require significant energy and capital. The company plans to expand to other cities, though regulatory hurdles around water reuse vary widely by jurisdiction.
Founded by a team of engineers and brewers with backgrounds in environmental science, the startup has raised an undisclosed sum from impact investors. One local bar owner remarked, "People come for the novelty but stay for the taste—it's genuinely good beer."
