The Walla Walla Valley is a viticultural area of superlatives, not just in terms of the wines it produces, but also in the sense of the geologic events in which it and its soils were created. Our climate could not be more suitable to world-class wine production, as our growing season is long, warm, and virtually devoid of rainfall as a result of the rainshadow effect of the Cascade mountain range. As a result of this, we are able to control the growth of the vines through cautious irrigation of our deep, well-drained soils. These soils were formed approximately thirteen thousand years ago. During this time, a series of enormous floods, known as the 'Bretz' or 'Spokane' floods inundated the Walla Walla Valley as glaciers retreated toward the poles at the end of the last ice age, to an elevation of 1200 feet. The silt deposits left behind by the floods were picked up by the prevailing winds and blown into what are now stunning rolling hills of 'Loess' (pronounced 'luss") which surround the Walla Walla Valley on all sides. At the same time as the floods, Mt. Mazama in Oregon was continually erupting, and the fallout from the explosions gave our soils a relatively high percentage (10-15%) of volcanic glass, which contributes to fertility and excellent water drainage. We are so lucky to be working in the soils and climate of the Walla Walla Valley, and believe that it is growing, and will continue to grow, some of the finest wine grapes on earth.
