our vineyard

We believe that great wines are created in the vineyard. Meticulous farming and a natural approach to winemaking cultivate the truest expression of our vineyard; creating wines that express the nuances of each block with clarity, depth and richness. Our 16-acre Estate Vineyard is situated on a gentle, west facing slope in the Yountville Appellation. The vineyard consists of gravelly alluvial soil layered over sandstone bedrock, avoiding the vigor of deep, rich soil. This well drained site produces tiny, thick-skinned berries and wines with distinctive characteristics of deep black fruit flavors, earthy minerality, structure and powerful tannins.


The vineyard is divided into micro-blocks of thirteen clones of Cabernet Sauvignon, two clones of Merlot, and two clones each of Cabernet Franc and Petit Verdot. The vines are densely planted to a variety of rootstocks carefully matched to the soil; each clonal block is farmed separately. The blocks are fermented individually, yielding a distinctive palette of fruit and flavors from which the Gemstone are born.
