Realm Cellars is a wine producer located in Napa Valley, in the Stags Leap district. The winery has gained recognition for its Cabernet Sauvignon-based wines, sourced from high-quality vineyards, and has quickly become one of the cult producers in the region. Founded in 2002, Realm Cellars started as a virtual winery, utilizing grapes from other renowned vineyards to craft its wines. Initially, the wines were made at Sherwin Family Vineyards in Spring Mountain, before production moved to Chateau Boswell near St. Helena. The current majority owner, Scott Becker, has brought a new focus to the winery, which now has its own vineyard following the acquisition of Hartwell Estate Vineyards in the Stags Leap District in late 2015. Starting with the 2016 vintage, winemaking began to occur at the former Hartwell winery. Currently, production is equally divided between single-vineyard wines and proprietary blends from various locations in Napa.
