Soil Types

There are 60 different soil types within the properties that we manage. The soil series ranges from clay to the finest sandy loams. Due to the immense diversity of soil types, we spend a significant amount of time researching the appropriate rootstock and clone types in order to produce quality fruit. The dominant soil series includes 128 Cropley Clay, 163 Los Osos Diablo Complex, and 216 Tierra Sandy Loam.

In some of our vineyards we have discovered the soils to be comprised of not only clay loam, but marine sediment and also some volcanic rock (serpentine) elements. This addition of serpentine soil in some areas includes high levels of magnesium, which makes our vineyard practices challenging at times.
