SAN DIEGO, Calif. – An unusual brew is grabbing headlines out west.

San Diego Mayor Kevin Faulconer joined others in raising a glass Thursday to toast Stone Brewing's new "Pure Water" beer.

The sustainable blend is made using recycled water from the city's pure water facility, designed to give people a taste of the future.

The city hopes to use purification technology that some have nicknamed "toilet tap" to create about a third of San Diego's water supply by 2035.
