A collection of single-vineyard wines sculpted from Napa Valley’s ancient soils.

Lithology – /lIˈθɒlədʒi/ – noun

The study of the formation, composition, and classification of rocks.

Napa Valley is a tale of fire and ash, molten rock, and explosive geological forces that etched their mark upon the land millennia ago. Over time, this substance has weathered and decomposed, creating soil that is rich in minerals and well-drained — the perfect conditions for exceptional grapevines to thrive. In these unique soils, our acclaimed winemakers dig a little deeper to create a distinguished collection of wines, each a powerful testament to the earth’s ability to shape and refine the flavors in your glass.

Our story

At Lithology, we draw inspiration from Napa Valley’s ancient terrain, crafting wines as layered as the soils from which they emerge. Rooted in the original stone building on Meadowood Lane, our winery is a testament to our commitment to tradition and innovation. Our grapes are sourced from esteemed vineyards in Oakville, Rutherford, and St. Helena, where hot days and cool nights foster the ideal conditions for producing world-class Cabernet Sauvignon and Cabernet Franc.

Guided by a visionary team, including owner Alejandro Bulgheroni, an esteemed international vintner and entrepreneur renowned for his humanitarian and ecological endeavors, Lithology embodies a spirit of innovation and excellence.
