GEMSTONE VINEYARDS is a unique 16 acre vineyard site with a rich history of producing exceptional Cabernet Sauvignon for over 25 years. Our vineyard is sustainably farmed and meticulously maintained, pruned and harvested by hand. Situated on a gradual, western facing slope in the Yountville appellation, GEMSTONE is truly a study of terroir. It is comprised of gravelly alluvial deposits from the volcanic soils of nearby Pritchard Hill, layered on top of sandstone bedrock and interspersed with remnants of the fluvial floodplain that worked tirelessly for centuries to create the verdant and fertile basin of the Napa Valley below. On this unique and varied site we have planted 20 micro-blocks of heritage grape varieties including 11 different clones of heirloom Cabernet Sauvignon vines, plus multiple hand-selected rootstocks and extensive variation in trellising systems.

We are fortunate to partner with winemaker Thomas Rivers Brown, one of the most extraordinary talents in winemaking today. His non-interventionist approach aligns with our commitment to terroir, allowing our vineyard’s character to guide the style of our wines. Originally from South Carolina, Thomas made his way to Napa Valley in the mid-1990’s after graduating from the University of Virginia. He underwent enviable training from some of the most respected and prestigious winemakers in the valley, honing his talent and extraordinary palate to become one of Napa Valley’s most sought-after winemakers. Since that time, Brown’s wines have garnered critical and public acclaim including being named Food + Wine’s, ‘Winemaker of the Year’ in 2017 and being featured as Wine Spectator's "Top Gun" in 2018."
