Gemstone
Gemstone is a boutique Napa Valley estate founded in 1996 on a 30-acre property in Yountville, producing Bordeaux-variety wines from estate-grown fruit. The Estate Red Wine and Facets of Gemstone are the flagship expressions — Cabernet Sauvignon-dominant blends with supporting Merlot, Cabernet Franc, Malbec, and Petit Verdot. The estate Yountville block grows on alluvial benchland soils with mixed gravel and clay, producing Cabernet of moderate weight and aromatic finesse rather than the mountain-fruit power of Howell Mountain or Spring Mountain. Philippe Melka consulted on winemaking for a period, lending the wines his characteristic precision and concentration. The estate produces approximately 1,500 cases across its range, with DTC distribution the primary sales channel. At auction, Gemstone averages $175 per bottle across 223 lots with a remarkable ceiling of $3,137 — the latter likely for an exceptional large-format lot or extraordinary library vintage from the estate's early production. The average price is consistent with boutique Yountville Bordeaux-blend territory, and the wide range ($20–$3,137) reflects both modern commercial releases and rare library bottles from the late 1990s and early 2000s when the estate was building its initial reputation. The Estate Cabernet Sauvignon and Facets of Gemstone have attracted favorable reviews from Wine Spectator and Vinous, with scores generally in the 91–93 range confirming the estate's consistent quality baseline.

In the Glass
Gemstone Estate Red is a refined, Yountville Bordeaux blend: blackcurrant, plum, cedar, tobacco, and floral lift from the Yountville valley floor terroir. The Cabernet Sauvignon backbone provides structure and aging potential; Merlot adds roundness and mid-palate texture; Cabernet Franc contributes aromatic complexity. The style is precise rather than powerful — well-integrated oak and polished tannins built for 10–20 years.
