Can Beer Be Made From Recycled Wastewater?

Stone Brewing unveiled its "Full Circle Pale Ale," which was made using recycled water from San Diego's Pure Water project.

This was all done in the name of sustainability, the brewery said, noting how the historic drought in California affected the state's water sources. San Diego's Pure Water project — which aims to provide 30 million gallons (110 million liters) of recycled water a day to the city by 2021 — offered the brewery an opportunity to use a new water source to brew beer, while also helping raise awareness for the project.
