Open: Year Round
Steinbeck Vineyards is comprised of 500 acres of premium wine grapes. The beautiful rolling hills are primarily sandy loam and clay soils. There are two primary soil groups found on Steinbeck Vineyards. The first is Arbuckle-Positas-San Ysidro group, which is characterized by very deep, nearly level to hilly, moderately well drained and well drained fine sandy loams, coarse loams, and loams.
The second is Nacimiento-Ayar group, characterized by moderately deep, strongly sloping to steep, well drained silty clay loams and silty clay. The oak trees, after which Paso Robles - The Pass of the Oaks, is named, thrive in this poor soil and so do our grape vines. As the vines are stressed they perform to their maximum potential, therefore producing a high quality fruit, consistent from year to year.
