Recycled water was used to make Stone Brewing’s Full Circle Pale Ale – a pioneering effort that’s winning kudos for the City of San Diego. San Diego partnered with Stone Brewing in 2017 to create the beer using advanced-treatment recycled water from the city’s Pure Water Demonstration Facility. The limited-edition beer was served only at an event at the brewery’s Liberty Station restaurant on March 16, 2017, a day Mayor Kevin Faulconer proclaimed “Pure Stone Day” in San Diego. It is no longer available to the public.
