Washington's Red Mountain AVA

At Long Shadows, we source fruit from some of the best vineyard sites in Washington. A number of those vineyards are found in Red Mountain AVA.

This AVA is part of the larger Yakima Valley AVA, which is part of the larger Columbia Valley AVA. It is located between a bend in the Yakima River in south central Washington, about 75 miles ENE of Walla Walla.

Red Mountain is neither red, nor a mountain, but the area does take on a reddish hue in springtime as the cheatgrass changes color. It's a very small, very warm region.

In 1975, the first vineyard on Red Mountain was planted mainly as an experiment. The following harvests proved that the land had something special to offer.

Formed by the Missoula floods over 10,000 years ago, this great geologic event scraped hills and reformed the land, depositing mineral rich soils throughout Washington and Oregon.

The terroir of Red Mountain can be attributed to a number of factors. The high alkalinity and calcium rich soil encourage the vines to go deep for resources, establishing a robust root system that generates character and nuance. Other factors like perfect slope and sun exposure, a long and dry growing season, and warming winds in the summer and cooling winds in the fall all contribute to concentrated berries and depth of flavor.

The fruit from the Red Mountain AVA provide backbone, dark fruit flavors, and incredible intensity of color.
