The site for the vineyard was selected after an extensive study of the area that matched Stephan's experience as a vigneron. He immediately favored the west side of Paso Robles for its sloping hills and authentic quality terroir. The one hundred twenty seven acre property he chose is comprised of multiple hills of various elevation, complex soils and excellent water drainage. He finds the aspects of this terroir to be fundamental in obtaining the high quality fruit necessary to create the wines he has envisioned for L'Aventure.

Because of its close proximity to the ocean, the vineyard is characterized by warm clear days with night time temperatures which can drop by approximately 40 to 50 degrees. This dramatic temperature variation increases the time of the grapes maturation cycle providing fruit that creates a more complex and balanced wine. With clear, sunny days typically lasting well into November, our fruit has the chance to stay on the vine longer to develop mature polyphenols, while the cool nights help retain acids, resulting in the ideal combination of maturity and balance.

The rolling hills that define the vineyard provide multiple facings on which Stephan strategically planted vines with carefully chosen grafted rootstocks. The thin layer of topsoil on these hills covers a succession of siliceous and calcareous shale which consists of old marine bones, shells, diatoms and plankton slowly deposited on the sea bed over millions of years, only to be lifted up through tectonic activity. The combination of these base soils with clay, metals and quartz contribute to the complexity of the fruit in multiple ways. This soil locks up nutrients coaxing the vines to create small, thick skinned berries to ensure protection of its precious seeds. The shale also acts like a sponge, storing water during the rainy season and redistributing it back to the roots in dry season. This assures a perfect feeding for the vines, giving them a balanced water source from which they regulate themselves, as opposed to the bingeing characteristics typically developed with irrigation. The shale also coaxes the vines to send roots deeper to collect water as the surface dries, rather than staying close to the surface and collecting from the drip system.Stephan's choice of this lean terroir provides him with the fruit necessary to create wine with a good balance between alcohol and acidity. The resulting wines are full and rich yet well balanced with finesse and elegance.
