✨ Technical Specifications
The Brosseau Vineyard Chardonnay from Bedrock Wine Co. is a stunning expression of one of California's most unique and extreme terroirs. Located in the remote Chalone AVA of Monterey County, the Brosseau Vineyard sits at a high elevation on the volcanic east side of the Salinas Valley. What makes this site legendary is its soil: a rare combination of decomposed granite and limestone, a geological signature highly coveted for Chardonnay. Planted in 1980 by Jon and Jan Brosseau, the vineyard is buffeted by cold winds and intense high-altitude sunlight, yielding grapes with concentrated flavors and a fierce, natural acidity. Winemaker Morgan Twain-Peterson MW coaxes out this dramatic terroir using native yeast fermentation and aging in French oak barrels, with a minimal-intervention approach that prioritizes the vineyard's signature saline minerality, structural tension, and rich, textured stone fruit character over heavy oak influence.
🍾 About the Producer
Established in 2007 by Morgan Twain-Peterson MW—later joined by partner Chris Cottrell—Bedrock Wine Co. began in a converted chicken coop with an urgent viticultural ethos: preserving California's precious heritage vineyards. The winery works closely with ancient, multi-varietal field blends across diverse terroirs, including volcanic, alluvium, granitic, and decomposed limestone parcels spanning Sonoma Valley, Contra Costa County, and the Central Coast. Central to the estate's identity is the historic Bedrock Vineyard, originally planted in 1854, which achieved Regenerative Organic Certification. Bedrock champions dry farming, minimal intervention, and historic head-trained vines. In the cellar, Twain-Peterson employs spontaneous native yeast fermentation, whole-cluster inclusions, and neutral wood, studiously avoiding chemical adjustments or excessive extraction. Beyond its legendary red heritage bottlings, Bedrock crafts benchmark whites and rosés—including the perfumed Compagni Portis Heirloom White, crystalline Wirz Vineyard Riesling, and artisanal expressions of Bien Nacido Chardonnay and Ode to Lulu Rosé—each presenting remarkable tension, saline minerality, and profound historic authenticity.
