Adelaida's wines begin at the roots, pushing through the rocky limestone soils on the west side of Paso Robles on California's Central Coast. The winery, which originated in 1981, is located 14 miles east of the Pacific Ocean at an elevation of 1,800 feet in the Santa Lucia mountain chain. The winery is a vineyard driven operation that considers itself a foremost proponent of the potential of west side Paso Robles. Adelaida's wild and rugged mountainside vineyards are loaded with limestone and calcareous shale. According to winemaker Terry Culton, "these characteristics cause the vines to strengthen. This results in added stress on the vines, which lowers the yields but produces more intensely flavored fruit". In keeping with the winery's sustainable philosophy, the vineyards are not tilled, encouraging native grasses, wild sage and rosemary to flourish between the rows. Adelaida produces from its own Estate vineyards and a select group of contracted vineyards on the west side of Paso Robles. Amongst its holdings are the two principal estate properties, Viking Vineyard and HMR Vineyard. The mighty Viking Vineyard was planted in 1992 and is now producing great Cabernet Sauvignon and Syrah. The historic HMR Vineyard was pioneered by Dr. Stanley Hoffman in the early 60s. Devoted care and substantial investment have returned these 40+ year old vineyards to their former glory. Intense, high quality wines are convincing first-time tasters and experts alike.
