Exploring Moon Mountain: Sonoma’s Volcanic Organic Wine Paradise Chris Lehoux, July 8, 2026 Vineyard history in the Moon Mountain District traces back to the 1880s when pioneering vintners discovered the region’s rich volcanic soils on the hillsides west of Sonoma. Over a century later, this area became notable for its organic viticulture, leading to its official designation as a unique American Viticultural Area (AVA) in 2013. The Moon Mountain District, named after its eponymous peak, spans 17,663 acres, including over 1,500 acres of vineyards. This area stands out for its combination of volcanic soils, higher elevation, and historical relevance to California’s modern organic wine movement. Within its boundaries, around 16 wineries thrive, sourcing grapes from more than 70 vineyards, many of which also supply fruit to other producers beyond the AVA. The region is distinguished by its volcanic soils and high-elevation winemaking conditions, making it a unique environment conducive to producing high-quality wines. The Moon Mountain District not only showcases the potential of California’s diverse growing conditions but also serves as a focal point for the organic viticulture movement, contributing significantly to the evolution of wine production in the area.
