Dunham Cellars

A Winery Built Where Planes Once Taxied

The eastern edge of Walla Walla Regional Airport is not the most obvious place to go looking for serious wine. Yet the low-profile industrial buildings along Boeing Avenue have become one of Washington State's more consequential winemaking addresses. Dunham Cellars sits in a repurposed aircraft hangar, a building type that does not apologise for its utilitarian origins. High ceilings, concrete floors, and steel framing define the space. What the building lacks in rustic charm it compensates for with a clarity of purpose: this is a production facility first, and a tasting destination second. That ordering matters when you consider how Walla Walla's wine scene has developed over the past three decades.

Washington's premium wine corridor expanded rapidly through the 1990s and 2000s, pulling in producers who ranged from boutique family operations to well-capitalised out-of-state investors. The wineries that built lasting reputations, rather than just early buzz, tended to share a common orientation: they treated vineyard sourcing as a long-term programme rather than a transactional relationship, and they prioritised consistency in the bottle over novelty in the tasting room. Dunham Cellars, holding a Pearl 2 Star Prestige rating from EP Club in 2025, sits within that tradition-minded cohort.

The Walla Walla Producer Context

Placing Dunham Cellars inside its competitive set requires understanding how Walla Walla's winery population stratifies. At the lower end, there are approachable tourist-facing operations that use the appellation's reputation to drive tasting-room traffic. In the middle, a dense cluster of producers makes creditable red wines from established Washington vineyards but competes primarily on price and distribution reach. At the upper end, a smaller group works with named vineyard sources, applies measurable production discipline, and earns recognition from publication ratings and competition results. Dunham sits in that upper bracket.

Producers like Gramercy Cellars and Sleight of Hand Cellars occupy overlapping territory within the Walla Walla recognition tier, each bringing distinct stylistic approaches to Washington Syrah and Cabernet. K Vintners operates at the more expressive, high-extraction end of the spectrum. Doubleback targets the collector tier with allocation-model Cabernet. Duckhorn's Canvasback label brings Napa capital and distribution muscle to Red Mountain fruit. Dunham's positioning differs from all of these: it combines production scale with individual wine character, reaching a wider retail footprint than most boutique Walla Walla houses while maintaining the kind of critical standing that warrants a prestige rating.

Viticulture, Terroir, and the Eastern Washington Growing Argument

The editorial angle that matters most when assessing any Washington producer is not style or packaging but the sourcing relationship with eastern Washington's established vineyard sites. The Columbia Valley and its sub-appellations, including Walla Walla, Horse Heaven Hills, Red Mountain, and Yakima Valley, produce grapes under conditions that differ substantially from the Pacific Coast wine regions that dominate national conversation. Continental climate patterns mean large diurnal temperature swings during the growing season, which preserves acidity in ripe fruit. Basalt and sandy loam soils, many of them deposited by the Missoula Floods, drain rapidly and stress vines into concentration. Irrigation, managed carefully, controls crop levels in a desert-margin environment where dry-farmed viticulture is the exception rather than the norm.

The sustainability conversation in Washington wine has evolved alongside these soil and climate realities. Unlike California's Central Coast or Oregon's Willamette Valley, where organic and biodynamic certification movements gained early traction and significant public profile, Washington's premium producers have generally approached sustainable viticulture through a more pragmatic lens. That does not mean corners are cut; it means the conversation is less driven by certification marketing and more by the practical realities of growing grapes in a semi-arid region where water management, canopy control, and soil health require responses calibrated to local conditions rather than borrowed frameworks. Producers operating in the upper tier of the Walla Walla recognition set, Dunham among them, are competing on wine quality in a market that reads transparency about farming practices as a baseline expectation rather than a differentiator.

For visitors who care about how grapes are grown, the relevant question when tasting Walla Walla wines is not whether a certification logo appears on the label but what the winery can tell you about the vineyards supplying its fruit, how those sites are managed, and what the farming relationship looks like across multiple vintages. That kind of sourcing depth is what separates a prestige-tier producer from a label operation.

What to Expect on a Visit

The Boeing Avenue address gives Dunham Cellars a different character from the estate wineries set back among vines on Lowden School Road or along the Seven Hills Road corridor. Arriving here feels more like visiting a working production facility than a curated hospitality experience, which is either a drawback or an advantage depending on what you want from a winery visit. For those whose primary interest is the wine, the industrial honesty of the space focuses attention on the product rather than the scenery.

Walla Walla's wine tourism infrastructure has matured significantly, and most prestige-tier producers now maintain staffed tasting rooms with structured programmes. EP Club recommends checking current tasting availability directly before planning a visit, as appointment requirements and seasonal hours vary across the winery calendar. The city sits roughly four hours from Seattle and two and a half hours from Portland, making it a logical long-weekend destination rather than a day trip from either major gateway.

Placing Dunham in a Wider American Wine Conversation

The prestige ratings that EP Club assigns allow useful cross-regional comparisons. A Pearl 2 Star Prestige designation places Dunham Cellars in productive conversation with producers from other American regions operating at equivalent recognition levels, including Accendo Cellars in St. Helena, Adelaida Vineyards in Paso Robles, and Adelsheim Vineyard in Newberg. Each of those producers operates within a distinct regional tradition, and the comparison is not about stylistic similarity but about the shared standard of production discipline and critical acknowledgment that a prestige rating signals. Beyond the United States, the same rating framework connects to producers such as Abadía Retuerta in Sardón de Duero and even, through the breadth of the EP Club programme, sites as different as Aberlour in Speyside. The point is not equivalence of product but equivalence of standing within a curated, editorially assessed tier.

Washington Cabernet Sauvignon has spent the past decade earning a more confident position in the national conversation about serious American red wine, no longer needing Napa as its reference point. Dunham Cellars, operating from its hangar on the airport's edge, is part of the case for that argument.
