Simply put, the vineyards at Éritage have the potential to produce wines of exceptional quality. When combining the caliber of terroir with the expertise of Éritage’s vineyard management team, We have very high expectations for these vineyards. At the onset of due diligence for Éritage, Dr. Kevin Pogue was recruited to provide a complete geological assessment of the Éritage estates, their underlying terroir and their potential for producing the very best wine grapes possible. Without this validation and the presence of exceptional water rights, Éritage would not have been created.Dr. Pogue is a Structural Geologist specializing in the research of geological and geographical controls on the terroir of the Walla Walla Valley American Viticulture Area.

The temperatures are dry and warm throughout the growing season, which in late June and early August often exceed 100 degrees. Based on similarly situated vineyards, average temperatures and growing degree-day (GDD) values should be slightly above average for the Walla Walla Valley AVA. This is especially important when encountering winter freeze, as the higher temperatures and air drainage at Éritage will help prevent frost damage.

Éritage receives annual rainfall of just 12-16 inches, which occurs primarily in the late fall through late spring. With such limited precipitation (due to our position well east of the Cascade Mountain range), we must have reliable irrigation to sustain the vineyards. The valuable combination of dry climate, precise irrigation and well-draining soils allows us to completely control soil moisture, nutrition and stress throughout the growing season to optimize the corresponding fruit production.

The elevations at Éritage range from 890 to 1080 feet across gently sloping hillsides, with both north- and south-facing exposure. The combination of slopes, hilltops and ridge crests offers the ideal balance of excellent cold air drainage and optimal heat unit exposure.

Although not exposed, Columbia River basalt forms the bedrock of the property, covered by a 10 foot layer of windblown (loess) soils of the Walla Walla series. These well-draining soils throughout the property are remarkably consistent, and generally composed of fine sand, gravel, clay and silt.
