Which valley serves as a shared appellation between Washington and Oregon?

Willamette Valley
Columbia Gorge
Snake River Valley
Redwood Valley

The correct answer is: Columbia Gorge

The Columbia Gorge is indeed the correct choice as a shared appellation between Washington and Oregon. This unique region straddles the Columbia River and benefits from diverse microclimates and varied elevations, which allow for a wide range of grape varieties to thrive. The geology of the area, combined with its cooler temperatures and significant sunlight, creates an ideal environment for viticulture, making it a noteworthy wine-producing region shared by both states. The Willamette Valley is primarily located in Oregon and is well known for its exceptional Pinot Noir, but it does not extend into Washington. The Snake River Valley is primarily associated with Idaho, although it does have some overlap with eastern Washington. Redwood Valley, on the other hand, is located in California, away from the shared geography of Washington and Oregon.
