Walla Walla Valley

Quick answer: what is Walla Walla Valley?

Walla Walla Valley is an established American Viticultural Area in the inland Pacific Northwest of the United States. The AVA was established on 6 February 1984 and crosses two states: south-eastern Washington and north-eastern Oregon.

For an Australian wine learner, the simplest comparison is with a recognised Australian wine GI. Both communicate where grapes were grown, although an American Viticultural Area and an Australian Geographical Indication are different legal systems.

Walla Walla Valley is best known for red wines based on Cabernet Sauvignon, Merlot and Syrah. Its warm, dry inland climate can support ripe fruit and full-bodied wines, while cool nights may help preserve acidity. These are broad regional tendencies, not promises: wines vary with grape variety, site, vintage and winemaking.

Where is Walla Walla Valley?

The region is in the inland Pacific Northwest, east of the Cascade Range and near the Blue Mountains. It is not on the United States’ Pacific coast.

The most useful regional centre is Walla Walla, Washington. The city is an orientation point and gives the AVA its name, but the city and the legal wine region are not the same thing. The AVA also includes land in Oregon, including the area around Milton-Freewater.

From Portland, Oregon, Walla Walla Valley is roughly 400 kilometres east. Treat that as broad orientation rather than a precise travel promise: the actual distance and driving time depend on the destination, route and traffic.

The basic hierarchy is:

• United States
• Washington State and Oregon
• Columbia Valley AVA
• Walla Walla Valley AVA

The Columbia Valley AVA is the larger designation. Walla Walla Valley is one of the more specific AVAs within that wider context.

What does AVA mean?

An American Viticultural Area is a federally recognised grape-growing area in the United States. Its boundaries are defined through the country’s regulatory system and are not simply the same as a town, county or visible valley.

This matters because the name on a bottle can describe different levels of geography. A wine may be labelled with a broad designation such as Washington or Columbia Valley, or with the more specific Walla Walla Valley. A smaller AVA may also appear.

The Rocks District of Milton-Freewater is a separate AVA nested within Walla Walla Valley on the Oregon side. It is not another name for the entire Walla Walla Valley AVA.

Climate, landscape and soils

Walla Walla Valley has a warm, dry, inland climate influenced by the wider Columbia Basin. Warm summer days can assist grape ripening, while cooler nights can help retain freshness and natural acidity.

The valley is not climatically uniform. Reported elevations range approximately from 122 to 610 metres, and rainfall varies from about 178 millimetres in the western valley to about 559 millimetres near the Blue Mountain foothills. These figures are useful for understanding regional variation, not conditions in every vineyard.

The region also contains different soil materials, including wind-blown loess, basalt-related material, sand and gravel, as well as deposits associated with ancient glacial floods. It is more accurate to think of Walla Walla Valley as a collection of varied sites than as one single soil type.

That variation does not allow a simple formula such as “this soil always creates this flavour”. Elevation, slope, exposure, irrigation, vine material, harvest timing and winemaking also influence the finished wine.

Which grapes and wine styles matter?

The principal varieties most strongly supported by regional industry evidence are:

• Cabernet Sauvignon
• Merlot
• Syrah

Cabernet Sauvignon may appear on its own or in blends with Merlot and other Bordeaux-associated varieties. Syrah is the same grape that Australian readers commonly call Shiraz, although a Walla Walla Syrah does not have to taste like an Australian Shiraz.

The region is broadly associated with structured red wines, including varietal Cabernet Sauvignon, Merlot and Syrah, as well as Bordeaux- or Rhône-influenced blends. Warm conditions can encourage ripe fruit, colour and body. Cool nights may help retain acidity, while tannin can provide firmness and shape.

In the glass, regional examples may show ripe black or blue fruit, noticeable body, firm or supple tannin, and savoury, herbal or spicy notes. But “Walla Walla Valley” does not guarantee that a wine will be bold, full-bodied, sweet-tasting or heavily tannic. The grape, producer, site and vintage all matter.

How should Australians read a Walla Walla Valley label?

When you see Walla Walla Valley on a bottle, think “specific place of origin”, not “a particular recipe”.

A useful tasting exercise is to ask:

1. Is the wine Cabernet Sauvignon, Merlot, Syrah or a blend?
2. Does it taste ripe and full-bodied, or more savoury and restrained?
3. How does its acidity balance the fruit and alcohol?
4. Is the tannin firm, polished or drying?
5. Does the label name Walla Walla Valley, the broader Columbia Valley, Washington State or a smaller AVA?

A Walla Walla Valley wine is geographically more specific than a generic Washington wine description. However, the designation still does not make every bottle taste alike.

Common questions

Is Walla Walla Valley in Washington or Oregon?

Both. The legal Walla Walla Valley AVA crosses south-eastern Washington State and north-eastern Oregon.

Is Walla Walla Valley the same as Walla Walla city?

No. Walla Walla is a city in Washington and the main regional reference point. Walla Walla Valley is the larger, cross-border wine-growing area.

Is Walla Walla Valley part of Columbia Valley?

Yes. Walla Walla Valley is within the broader Columbia Valley AVA.

Is Walla Walla Valley known for Shiraz?

The grape is generally called Syrah in United States wine contexts. Australian readers will recognise it as the same grape commonly called Shiraz in Australia. Cabernet Sauvignon, Merlot and Syrah are the region’s principal associated varieties.

Is The Rocks District of Milton-Freewater the same region?

No. It is a separate Oregon AVA nested within Walla Walla Valley.
