Tucked at the southern gateway of wine country, Sonoma offers something Napa can’t: a slower pace, deeper roots, and historic charm.
While Napa Valley gets much of the spotlight, South Sonoma is where California winemaking began — and where travelers in search of authenticity and beauty are richly rewarded.
In this post, we explore four must-visit estates — Viansa, Gloria Ferrer, Buena Vista, and Sebastiani — while diving into the story of Sonoma’s iconic plaza, California’s first vineyards, and why this region continues to thrive with old-world heart and new-world flavor.
📜 A Quick History of Sonoma
Founded in 1835, Sonoma was built around the Sonoma Plaza, still the largest town square in California
It was the site of the 1846 Bear Flag Revolt, which led to California’s transition from Mexican to American rule
Franciscan monks planted the first mission vineyards here in the early 1800s, laying the foundation for modern winemaking
