Tucked into the steep western slope of the Mayacamas Mountains, Sonoma Valley’s newest AVA begins at 400 feet above sea level and rises to the skies above the valley floor, reaching up to 2,700 feet at its peak.

  • Climate: Almost constant bay breezes blow across an entire AVA perched above the average summer fog-line.
  • Soils: The soils of Moon Mountain consist largely of fractured basalt and volcanic ash.
  • Varietals: While home to the historic Monte Rosso Zinfandel, Cabernet Sauvignon is now dominant on these hillside vineyards.
