✨ Technical Specifications
Sourced from the historic Wirz Vineyard in San Benito County's Cienega Valley, Bedrock Wine Co.'s 'Zweiter Zweieiiger Zwilling' (German for 'second fraternal twin') Riesling is a brilliant testament to California's old-vine potential. Planted in 1964 on own roots, these dry-farmed, head-trained vines thrive in decomposed granite and limestone soils under dramatic diurnal temperature swings. Winemaker Morgan Twain-Peterson MW crafted this bottling as part of a 'twin' experiment, exploring how different cellar techniques can coax contrasting personalities from the exact same harvest. This 'second twin' typically undergoes a distinct fermentation path—often incorporating elements of skin contact, native yeast fermentation, and aging in neutral wood—resulting in a textured, deeply mineral, and aromatic white wine that challenges conventional domestic Riesling expectations.
🍾 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.
