🔍 Quick Summary

Fort Ross‑Seaview AVA is a remote, high‑elevation coastal ridge within the Sonoma Coast, defined by fog‑free warmth, rugged terrain, and rare, terroir‑driven Pinot Noir and Chardonnay.

📜 History

  • Late 1800s: First planted by Italian settlers and S.P. Hallengren in 1872–1884.

  • 1960s: Much of the ranch was repurposed to create Lake Sonoma; viticulture paused.

  • 1990s: Earliest replantings began around 1992 by Rod and Cathy Park.

  • 2002: Officially designated an AVA—the 12th appellation in Sonoma County.

🧠 What to Know

  1. High-Elevation Refuge – All vineyards lie above 800 feet and extend up to 1,900 ft—above fog influence.

  2. Rocky, Thin Soils – Shallow, iron-rich loam and clay-loam soils drive low yields and flavor concentration.

  3. Invigorating Breath of Wind – Constant breezes and cool nights counterbalance intense sun—promoting even ripening and retaining acid.

  4. Tiny Planted Footprint – Spanning ~15,000 acres, only ~160–190 acres are under vine.

  5. Bold Red Grapes Thrive – Zinfandel leads the pack, followed by Petite Sirah, Syrah, Cabernet Sauvignon, Cabernet Franc, and more. Blanc varietals are rare.

  • 🌞 Climate: Warm, sunny days with cooldown from marine breezes; minimal fog due to inversion layer above Lake Sonoma.

  • 🌡️ Historical Temp Summary: Moderate heat and consistent daily temps deliver balanced ripening with retention of acidity.

  • 🔺 Warming Trend: While specific data isn’t cited, temperature shifts could further affect this already extreme growing site.
