Napa Valley's
Hidden
Treasure
Family-owned since 1994 — where 25 acres of estate vineyards meet ancient cave cellars carved from volcanic bedrock.
A Legacy Carved in Stone
Founded in 1994 by the Del Dotto family, our estate sits along the historic St. Helena Highway in the heart of Napa Valley. What began as a dream to craft wines of extraordinary character has grown into one of the valley's most distinctive destinations.
Our estate is defined by two extraordinary features: 25 acres of meticulously tended vineyards producing fruit of exceptional concentration, and a network of ancient limestone caves that stretch beneath our property — naturally cooled, perfectly humid, and ideal for aging wines to perfection.
Every bottle bearing the Del Dotto name carries the signature of this place — the mineral-rich soils, the morning fog rolling through the Mayacamas, and a family tradition of hospitality that dates back generations.
