Spirit Works Distilling was founded in 2012 by husband and wife Timo and Ashby Marshall in Sebastopol, Sonoma County, California. The distillery was built around a grain-to-glass approach, with the Marshalls producing their own base spirits from grain rather than buying neutral spirit.
The distillery's main grain has been California red winter wheat sourced from the Sacramento area. The grain is milled, mashed and fermented on site before distillation. Spirit Works uses an 800-litre Carl hybrid pot still equipped with two rectifying columns. The longer 21-plate column can produce neutral spirit above 95% ABV, while the shorter five-plate column and pot are used for other distillation work.
The original range included vodka, gin and sloe gin, later expanding to wheat and rye whiskey, bourbon, barrel-aged gin and other small-batch spirits. The distillery's approach also included organic grains and on-site processing as part of its grain-to-glass production model.
In 2020, Spirit Works was named Distillery of the Year by the American Distilling Institute. The award recognised the distillery's spirits as well as its contribution to the American craft-distilling community.
Spirit Works operated a tasting room at The Barlow in Sebastopol for many years. The tasting room later closed, while the distillery continued its spirits business. The current Spirit Works website remains active and presents the company as a Sonoma County spirits producer.
