The Columbia Valley AVA is an expansive and diverse growing region, stretching across both Washington State and a small portion of Oregon. It covers a staggering 11 million acres (4.5 million hectares) of land, making it one of the largest AVAs in the United States. This vast area is about 185 miles (300 km) wide and 200 miles (320 km) long, showcasing the sheer magnitude of the Columbia Valley.
As a sommelier and brewer, I have had the opportunity to explore and appreciate the size and diversity of the Columbia Valley AVA firsthand. The region's expanse allows for a wide range of microclimates, soil types, and elevations, which in turn contribute to the rich variety of grapes grown here. From the fertile soils of the Yakima Valley to the rugged terrain of the Walla Walla Valley, each sub-region within the Columbia Valley AVA offers its own unique characteristics and flavors.
One of my most memorable experiences in the Columbia Valley was visiting the Red Mountain AVA, a small but highly regarded sub-region within the larger AVA. This area, known for its warm climate and iron-rich soils, produces some of the finest red wines in the region. Walking through the vineyards, I marveled at the sheer beauty of the landscape, with rows upon rows of grapevines stretching out as far as the eye could see.
The Columbia Valley AVA's size also allows for a diverse range of grape varieties to thrive. While it is known for its exceptional Cabernet Sauvignon, Merlot, and Syrah, the region also cultivates other varietals such as Chardonnay, Riesling, and Sauvignon Blanc. Each grape variety expresses itself differently depending on the unique terroir of the sub-region it is grown in, resulting in a captivating array of wines.
In addition to wine production, the Columbia Valley AVA is also home to a growing craft beer scene. With its abundant barley fields and access to pristine water sources, the region provides an ideal environment for brewing. I had the pleasure of visiting several breweries in the area and was impressed by the dedication of the brewers and their commitment to using locally sourced ingredients.
To summarize, the Columbia Valley AVA is a vast and diverse growing region, spanning across Washington State and a small portion of Oregon. With its 11 million acres of land, it offers a multitude of microclimates and soil types, allowing for a wide range of grape varieties to thrive. Whether exploring the vineyards or tasting the wines and beers produced here, the Columbia Valley AVA is a true testament to the beauty and bounty of the Pacific Northwest.
