Lithology is a producer of single-vineyard, small production wines sculpted from Napa Valley’s ancient soils.

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. Alejandro’s trust in our team, which includes the dynamic trio of winemaker Matt Sands, geologist Philippe Melka, and global wine influencer Michel Rolland, fuels our pursuit of enigmatic creativity and unparalleled quality.
