2,300 feet high at its peak, vineyards on Sonoma Mountain rise above the fog line, allowing grapes to ripen more fully in the extended hours of sunlight. A bit off the beaten path, Sonoma Mountain has a steep, rustic and faraway feeling.

• Climate: More sunlight means warmer days, but the altitude makes for chilly nights.
• Soils: Sonoma Mountain soils are volcanic-based and exceptionally well-draining.
• Varietals: Chardonnay and Cabernet Sauvignon flourish in this high altitude environment.
