Watermill Estate Vineyard

The soils of Watermill Estate Vineyard consist of very deep, excessively drained soils formed in basaltic alluvium mixed with loess at the surface. These soils contain a large fraction of fist size basalt cobblestones and unique geochemical signature (particularly higher levels of Iron), resulting in wines which are savory, with notes of roasted meat, olive tapenade, flowers and mineral. Syrah is the super star of the vineyard, displaying a bold, earthy character some people refer to as “The Rocks funk.” The Cabernet franc is one of the best we work with in Washington State as well. The bottom line, all the varietals tend to showcase deep color, complex flavors, silky tannins and savory aromatics.

Soil Type

Freewater very cobbly loam: Soils of the Freewater series are comprised mainly of basaltic alluvium derived from the erosion of the Blue Mountains. The course rocky nature of these soils provides many key viticultural advantages. Please click on the link for more in depth information on the distinguishing features of this soil type. The average annual precipitation is 11 inches.


The vineyard is situated in a little cooler area of alluvial fan. The Rocks District vineyards tend to bud break early and then slow way down during the final ripening phase due to a significant diurnal temperature swing.
