✨ Technical Specifications
Bedrock Wine Co.’s 'Erster Zweieiiger Zwilling' (meaning 'First Fraternal Twin') Riesling is a compelling exploration of vessel-driven winemaking and historic California terroir. Sourced from the legendary Wirz Vineyard in San Benito County's Cienega Valley, where own-rooted Riesling vines were planted in 1964 on decomposed granite and limestone, this wine represents one half of a unique experimental pair. To highlight how different aging vessels influence the same old-vine fruit, winemaker Morgan Twain-Peterson MW split the harvest: the 'Erster' twin was fermented and aged in a concrete egg. This vessel encourages continuous lees contact and gentle convection currents, resulting in a beautifully textured, mineral-driven white wine that balances Riesling's natural, high-toned acidity with a subtle, rounded weight and distinct saline finish.
🍾 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.
