Soil & Climate

Much of the soil composition at Defiance is the result of millions of years of marine shell deposit creating limestone layers. The soils are a clay loom, rich in limestone and sandstone. The vineyard employs a state of the art duel drip system to ensure detailed, accurate water management. 

One of the key ingredients to making Paso Robles a notable wine AVA, rests in the region's dramatic temperature swings between the daytime and night, especially close to harvest. Famous wine regions share commonalities in the Growing Degree Days (GDD) required to ripen and balance the wine. Heat ripens the fruit to promote the big and bold flavors unique to California. Coolness preserves the acidity required to add high notes and protect the complexity needed to make a wine interesting, agreeable and ageable. The combination of the two is responsible for the balance and structure of the wine.  Paso is uniquely situated to achieve the high end on both spectrums while averaging to a balanced GDD region, promoting an experimental and fun wine area. In fact, Tablas Creek likes to point out to its sister winery,  Château de Beaucastel in the Rhone valley, that while it’s 105 degrees in Paso and 80 degrees in the Rhone, it is in fact cooler in Paso.
