Perched at the summit of Diamond Mountain, CONSTANT has been a private homestead since the 1890s and continues to be a private home to this day, unspoiled and largely hidden from the public – until now. Over 100 years of light-handed farming, minimal winemaking, and a remote mountain sensibility have resulted in one of the most unique, pristinely-preserved, and bountiful vineyards in the Napa Valley, and we are excited to share our wines, available by allocation only.
