Planted in 1999, Denner Vineyards is a winegrowing estate on the far western border of the Paso Robles AVA. The 156 acres press up against the Santa Lucia Range, giving the site great diversity of elevation, aspect and soil. Previously dry farmed barley, the estate is nestled into the Templeton Gap, an East/West corridor where the marine layer can reach the inland valleys. As a result the estate receives large diurnal temperature swings without high moisture pressure, giving it a near perfect growing climate.
