Willamette Valley Wine Regions: A Traveler’s Guide

History of the Willamette Valley Wine Region

Willamette Valley Terroir

The Willamette Valley’s layout, cool climate, and diverse soils play a huge role in what ends up in your glass. From the protective mountains to the ocean breezes, everything works together to create the unique wines this Oregon wine country is known for. Let’s explore what makes this Pacific Northwest region so great for winemaking.

Geography

The Willamette Valley stretches about 100 miles from Portland in the north to Eugene in the south and 60 miles across. It sits between the Cascade Mountains to the east and the Coast Range to the west, protecting it from cold air and rain coming off the Pacific Ocean.

Shaped by the Missoula Floods at the end of the last Ice Age, the valley’s vineyards are mostly found on the western side of the Willamette River, on the slopes of the coastal mountains and in valleys formed by the river’s tributaries. The Van Duzer Corridor, a gap in the Coast Range Mountains, lets in cool ocean breezes that help keep the grapes’ acidity just right.

Vineyards are usually planted between 200 and 700 feet in elevation, avoiding the richer valley floor soils and cooler hilltops.

Climate

The Willamette Valley has a cool, mediterranean climate. The mountains around the valley protect it from cold Pacific winds and heavy coastal rains. So, while winters are cool and wet, summers are warm and dry, with hardly any rain from June to September.

Summer days see up to 16 hours of sunlight, giving the grapes plenty of time to ripen. But temps are moderated by morning fog and cool breezes that flow through the Van Duzer Corridor gap in the Coastal Range. This, combined with cool evenings, helps keep the wines’ fresh acidity.

With climate change, the valley is seeing warmer weather and drier conditions. This brings new challenges like droughts and unwelcome pests that survive winter.

Soils

The Willamette Valley’s soils are a big part of what makes its wines special. You’ll find three main types:

• Jory – A red volcanic soil that’s rich in clay and iron. The clay helps keep vines healthy during dry summers. Jory is known for helping Pinot Noir develop minerality and bright red fruit flavors.
• Willakenzie – A marine sedimentary soil that comes from ancient ocean floors. These soils make the vines work a bit harder, adding black fruits and structure to the wines.
• Laurelwood – A windblown loess soil. It’s more fertile than Willakenzie. But it’s shallow and drains well. This makes earthy wines with rustic tannins.

Willamette Valley Wines

The Willamette Valley is all about cool-climate wines. And Pinot Noir is the star. This grape thrives here, making up most of the valley’s vineyards. The style can vary a lot depending on the AVA and even the specific vineyard.

I tasted Pinot Noirs with bright red fruit flavors like cherry and raspberry, often with hints of spice or earthy undertones. And others that were more intense, with dark fruit and a fuller body.

Different clones of Pinot Noir add even more variety. Pommard and Wadensvil were most often used to start. But the Dijon clones from Burgundy became popular in the ‘90s. Each brings its own character to the wine. And clones are often blended to add complexity.

The Chardonnay really stood out for me here too. Winemakers are leaning toward a more Burgundian style. Some barrel fermentation is used, often in more neutral oak. And aging the wine on its lees may be done for added texture. But I found most of the Chardonnays still had a nice crispness.

Pinot Gris is another popular planting. Most I tasted were made in a fresh, fruity style, ranging from dry to off-dry. Some winemakers are experimenting with skin contact, giving the wine a deeper color and unique flavors.

Gamay Noir is also becoming a favorite grape variety. You can find light and fruity styles to bolder, age-worthy bottles.

American Viticultural Areas of the Willamette Valley

The Willamette Valley is home to 12 different American Viticultural Areas (AVAs), each with its own flavors and vibe depending on where the grapes are grown.

Whether you’re into bright, fruity Pinot Noir or something richer and more complex, you’ll find it here. Plus, there are plenty of other great white and red wines to explore.

Here’s a quick look at what makes each AVA unique.
