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.

Three Rivers Sources Grapes from Columbia Valley Among Others

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.

Some of our finest Chardonnay, Riesling, Cabernet Sauvignon, and Merlot come from Bacchus.

Gamache Vineyards

When Gamache first planted in 1982 there were less than two dozen wineries in Washington State. Nearly 30 years of grape growing has given the brothers an appreciation for the unique expression of the site.

Three Rivers receives Chardonnay, Sauvignon Blanc and Malbec from Gamache Vineyards.

Les Collines Vineyard

Les Collines (The Foothills) is one of the higher vineyards in the Walla Walla Valley sitting at the base of the Blue Mountains, with an upper elevation of 1,380 feet. Soil Moisture and weather data is recorded around the clock, producing high-end Merlot for Three Rivers.

Minnick Hills Vineyard

Minnick Hills Vineyard lies 2 miles north of Walla Walla at the point where the valley transitions to rolling hills. This is a perfect site for some of our red varieties including Cabernet Sauvignon and Merlot because of the soil diversity which includes volcanic ash that was deposited following the eruption of Mt. Mazama thousands of years ago.
