More About 2018 Immortal Estate Slope Sonoma County Cabernet Sauvignon Immortal Estate, formerly known as Hidden Ridge, was designed by Lynn Hofacket and Tim Milos in 1990. Since its inception, the property has produced perfect 100-point wines, gaining much attention from critics and collectors alike. Expertly harnessing the power of Mountain Cabernet Sauvignon, Tim Milos honed his winemaking skills at Opus One, Stag's Leap, and Cliff Lede. The incredibly steep vineyards of Immortal Estate rank among California's steepest, planted on a staggering 55-degree incline within the Mayacamas range. In 2018, Immortal's 50 acres of vines were divided into thirteen lots harvested over two weeks according to ripeness. The resulting wine is full-bodied and richly layered with tremendous complexity, length, and perfect balance.
