Tucked away on the corner of Reuss and Tesla Roads in the upper Livermore Valley is a 64-acre site, situated on a sloped, alluvial bench with well-draining, “outwash” shaly loam soils from the surrounding hillsides. The Ghielmetti family – with their highly-regarded consultants, Jim Regusci and Cary Gott – chose this spot for its potential quality. 



Sixth-generation winemaker & proprietor, Steven Kent Mirassou, recognized the vineyard’s potential as well, believing in 2007 that it had the inherently superlative qualities that would allow him to eventually create one of California’s First Growths.


Ghielmetti Estate Vineyard is roughly rectangular in shape but tends to flow downward from all sides (like a tablecloth pushed down in the middle) toward an arroyo that runs through the estate from north to south. The vineyard is topographically varied, ranging in elevation from 500 to almost 1000 feet above sea level. Within the site itself are a number of undulating blocks that provide different exposures to sun and wind. Varieties and clones were specifically and carefully chosen to take full advantage of the different climats these changes in elevation and varied soils provide.


Ghielmetti Estate Vineyard became the predominant fruit source for The Steven Kent Winery in 2005 and the source for Lineage | Livermore Valley in 2007. It is planted to all five of the classic Bordeaux varieties with multiple clones (separate blocks) of Cabernet Sauvignon, Merlot, and Petit Verdot.
