The distillery is capturing the fog working with sustainable water and fog researching nonprofit FogQuest.
In an effort led by head distiller Caley Shoemaker, Hangar One partnered with the organization to harvest fog for craft vodka making. The technology used is low cost and low energy, with specialized designed mesh used to power the process.
Shoemaker touted that the process is environmentally sound, in light of California's water shortage. Meanwhile, all profits to the vodka sales of the Fog Point vodkas go to the California Water Conservancy.
Inspired by the farmers she works with to create flavored vodkas, "I experience season change through what's available at the farmer's market," Shoemaker told CNBC.
"The drought is just the first thing that comes up every time — how that's affecting the fruit's quality, grape availability, the wine making and all that kind of stuff."
Vodka can be made with almost anything so long as it is distilled to 190 proof or higher.The water needed to bring the bottle back to 80 proof, in this case, is fog water.
By harnessing water this way, the distillery takes pressure off the environment in a time of severe drought. After six months of harvesting fog at about half a liter to a full liter per day, the distillery released just under 2,500 bottles. They've since sold out for retail sale but can still be found in restaurants.
In order to feed fog-thirsty patrons, the stuff is being caught in Berkeley Hills, Outer Sunset, the Presidio and Sutro Tower, which has yielded an above average return. More than just a gimmicky vodka, the move helps alleviate the stress of water usage in a state still grappling with a drought.
