Every winemaker knows that great wines are made in the vineyard and that he or she should do everything possible to work with the vineyard owners to produce premium grapes.

The Columbia Valley Terroir Offers Unique Growing Conditions

Columbia Valley Terroir Offers Exceptional Growing Conditions


Winemaker Holly Turner has been fortunate to have worked with fruit from nearly all parts of the vast Columbia Valley Appellation, thus developing a winemaking philosophy which is well suited to our area.

Each growing area in the Columbia Valley has its own unique characteristics that contribute to making the wines distinctive. The French use the term “terroir,” which refers to the factors at each growing site that contribute to making the wines unique. These factors include the soil type, irrigation management, canopy management, cropping levels, and overall climate. Occasionally, the grapes from an individual vineyard will be of such superb quality that they warrant being bottled separate from other vineyards to showcase the resulting wine.

Wine Blending

Holly strongly believes that the blending of grapes from several different vineyards will most often result in the most superb wines possible. At Three Rivers Winery, we utilize blending to maximize wine quality whenever warranted.

Blending of wines is analogous to cooking with herbs. When used alone, fresh herbs can enhance the flavor of most foods, but when several herbs are used in combination they can result in a superb culinary dish.

The Best Fruit

Three Rivers uses wine grapes from many different areas within the Columbia Valley Appellation, including high quality vineyards in both the Lower Columbia and Walla Walla Valley sub-Appellations. Several of these vineyards were recently planted and will not produce a usable crop for several years. We continue to source grapes from a wide array of vineyards in several diverse geographic zones to deliver the highest quality wines.
