Which AVA is characterized by a scenic gorge and diverse microclimates?

1. Yakima Valley

2. Columbia Gorge

3. Lake Chelan

4. Red Mountain

The correct answer is: Columbia Gorge

The Columbia Gorge AVA is recognized for its stunning geological features and a range of microclimates, which arise from its unique topography and climatic conditions. The gorge acts as a natural corridor that not only provides striking views but also creates varied environments for viticulture, with temperature variations and exposure levels that influence grape growing. This diversity allows for a wide array of grape varieties to thrive, each benefitting from the specific microclimate in which it is cultivated. The ability to grow different varietals in close proximity is a significant advantage for winemakers, which contributes to the region’s distinct wine character. In contrast, while regions like Yakima Valley and Lake Chelan also have their own unique features and climate considerations, they do not feature the same dramatic gorge landscape and range of microclimates that characterize the Columbia Gorge AVA. Red Mountain, known for its warm temperatures and excellent Cabernet Sauvignon, is more uniform in its climatic conditions than the Columbia Gorge, limiting the diversity of microclimates present.
