Bedrock Wine Co.

United States
Philosophy
Native fermentations with minimal handling: whole-cluster work, no inoculation, early harvest for acidity and terroir expression, minimal sorting to preserve fruit diversity, neutral oak preferred over new wood. The cellars embrace uninoculated fermentations and native malolactic conversion, racking sparingly.
Reputation
Bedrock Wine Co. was founded in 2007 by Morgan Twain-Peterson, Master of Wine and son of Ravenswood's Joel Peterson, in a converted 550-square-foot chicken coop on the outskirts of Sonoma. Born from a mission to preserve California's ancient field-blend vineyards—many dating to the 1880s and 1890s—the winery has evolved from humble redwood fermenters into a leading voice in regenerative viticulture, with its Bedrock Vineyard estate (planted in 1854) representing the foundation of the house's work.
AllocationBedrock Vineyard (41 ha per Regenerative Viticulture Foundation) verified as core holding; additional vineyard holdings across CA not fully quantified in sources (Evangelho, Pato, Compagni Portis, Nervo Ranch, et al. operate under different ownership models—some leased/farmed by Bedrock, some Bedrock-owned). Bedrock achieved Regenerative Organic Certification in 2025 on core estate vineyard—unique status as only ancient-vine site in California with this dual certification. Morgan Twain-Peterson is current owner/winemaker; Chris Cottrell joined as co-owner/partner in 2013. Production volume not stated in sources; small-batch artisanal producer (began with six barrels in 2007). Chris Cottrell addition date varies between sources as 2012 and 2013; earliest clear documentation is 2013 joining. UK importer confirmed as Berry Bros. & Rudd; US distribution includes multiple regional importers (Skurnik principal California distributor as of 2025); Japan importer not found in search results. Languages on labels and website: English only verified. Winemaker holds Master of Wine designation (achieved 2017). No parent company or succession concerns identified; family-owned and operated structure continuing.
