The Columbia Gorge AVA, America’s Most Unique Wine Region

The Land

The Columbia River Gorge AVA is extraordinary, interesting and unique. It lies within the boundaries of the Columbia River Gorge National Scenic Area and is, therefore, federally protected. The appellation lies along a 15 mile stretch of the River which is the Oregon and Washington border. At the western end the river is entering the Cascade Range; in the eastern segment the Columbia is exiting the desert. The latitude ranges between 45° and 46° north, the same as Bordeaux, the Loire Valley, Northern Rhone Valley, Piemonte and Veneto (Italy). This is a largely undiscovered tourism jewel, picked by National Geographic as one of the world’s top 10 destination areas. The Gorge is a magnet for outdoor sports enthusiasts — windsurfing, kite boarding, snow skiing (Mt. Hood), white water rafting, serious fishing, and mountain biking are featured.

Gorge Weather

The Gorge is an area of an incredible range of weather, with up to 60 inches of annual rainfall in the West, down to 9 inches in the East – in just 15 miles! The wind from March through September is relentless, blowing down the Gorge from the west-northwest, near Portland up to 30 miles per hour. Alsatian, Burgundian and Northern Italian grapes thrive in the West end; Bordeaux, Tuscany/Piedmont, Loire and Rhone varieties flourish in the East.

A Multitude of Microclimates

It’s the range of variables that makes this place so unique. The combinations of elevation (50-2000 ft.), heat units, cloud cover, rain levels, and an array of soil types, among other factors, means that virtually any wine grape variety can prosper here. Our chosen plantings include over 20 varieties of grapes from Cabernet Franc to Fiano. There are several unique sub-regions within our small AVA that include Underwood Mountain, the White Salmon River Valley, the Hood River Valley, Mosier, Lyle, and the western The Dalles areas.

Gorge Geology

Perhaps the most remarkable aspect of the Gorge is the influence of ice age floods, some 20,000 years ago. Layers of basalt that spread from Idaho, millions of years ago, have been carved out by (roughly) 20 massive flows of ice and water from the Missoula, Montana area. Ice dams periodically ruptured there, sending walls of water up to 1000 feet high racing through our basalt on the way to the sea, creating the Gorge. Many different soils were deposited along the way, while hillsides were stripped bare by the floods. This geologic history has further added to the diversity of terroirs in the AVA.



15 acres of  Cabernet franc, Syrah, Barbera, Dolcetto, Primitivo, Chenin blanc, Sauvignon blanc, plus 15 other varieties share the land with pears, cherries and other stone-fruit. The Farm sits at a 300 foot elevation, tilted slightly north, facing the Columbia. It is certified organic, and most of the grapes are dry-farmed.


3 acres of Sangiovese, Grenache & Primitivo, sustainably farmed in clay-loam soil with cobbles, at 600 foot elevation facing west to the river and the setting sun.
