Why This Region Matters
Volcanic Terroir
Calistoga's soils contain volcanic ash and basalt from Mount St. Helena — imparting a distinctive mineral and earthy character to the wines.
Medieval Castle Winery
Castello di Amorosa is an authentic 13th-century Tuscan castle hand-built over 14 years — the most unique winery experience in all of California.
Hot Springs Capital
Calistoga's geothermal hot springs have attracted wellness seekers since the 1860s. Indian Springs, Solage, and Four Seasons offer world-class spa experiences.
Schramsberg's Historic Caves
Carved in 1862 by Chinese laborers, Schramsberg's caves hold over 2 million aging bottles — and a cave tour is one of the finest winery experiences in Napa.
Climate & Terroir
Warmest part of the valley floor, with volcanic basalt and ash soils from nearby Mount St. Helena. Hot days produce bold, powerful Cabernets. Higher elevation mountain AVAs are cooler, yielding more structured, age-worthy wines.
