Caymus Vineyards was founded by the Wagner family in Rutherford, drawing on vineyard sources across Napa Valley’s diverse benchland and valley-floor soils. The “1858” designation references the year of the Wagner family’s early Napa Valley roots, reflecting the estate’s long-standing connection to the region’s agricultural heritage. The 2018 bottling centers on Napa Valley vineyard sourcing and the winery’s longstanding focus on Cabernet Sauvignon within the valley’s varied terroirs.
