The Oak That Started It All: How Westland's Garryana Series Rewrote the Rules of American Whiskey
There is a species of oak growing along the fog-swept lowlands of the Pacific Coast — one that predates the American whiskey industry by millennia — that is now at the center of one of the most compelling movements in craft distilling. Known as Garryana, Oregon white oak, or simply "Garry oak," it is a wood species native to America's Pacific Coast (scientific name: Quercus garryana) that, while ranging from British Columbia to Southern California, is most closely associated with the Pacific Northwest. For most of its history, the tree held little commercial relevance to the spirits world. That began to change when a scrappy Seattle distillery decided to barrel its single malt in Garry oak and dared to ask what the results might look like after years of patient maturation.
The answer, a decade and change later, is Edition 11 of Westland Distillery's Garryana American Single Malt — a release that arrives not merely as an annual collectible but as a statement of where the entire genre of American single malt is heading. For the 11th and newest version of its famed single malt, Westland continued to iterate on its own process, with the final blend incorporating over thirty cask types, including — for the first time ever — beer casks. That is a remarkable detail, even by the standards of a series already known for pushing every boundary it encounters.
A Distillery That Bet on the Pacific Northwest Before Anyone Else Did
Founded in 2010, Seattle's Westland Distillery helped popularize Pacific Northwest single malts. The founding vision was never to recreate a Scottish-style whisky with a Pacific Northwest label slapped on it. It was to interrogate what this specific corner of North America — its barley, its climate, its native forest — could actually contribute to the flavor of a glass of whisky. While the distillery uses the same basic ingredients and processes used for centuries by traditional Old World single malt producers, it does not simply seek to replicate the results of its Scottish predecessors.
Westland's co-founder Matt Hofmann — the distillery's master distiller and an honorary pioneer of the American single malt movement — fell in love with the style after going to Islay and experiencing the drams of Bruichladdich. But the ambition that followed that experience was distinctly American: to build something wholly original, rooted in a sense of place that Scotland could never replicate. The Pacific Northwest, with its maritime climate, its extraordinary barley-growing valleys, and its native oak, offered the raw materials to do exactly that.
All of Westland's expressions are distilled at the Seattle distillery from 100% malted barley and fermented with a unique Belgian Saison brewer's yeast before maturing in one of a variety of cask types, including new American oak, ex-Bourbon, ex-Sherry, and Garry oak, to name a few. That fermentation decision alone — choosing a Belgian Saison yeast rather than a conventional distilling strain — signals how differently Westland thinks about flavor construction. Unlike most single malt producers that stick to uniform and commoditized malt varietals, Westland's expressive malt bill adds unique layers of flavor at the very beginning of the whiskey-making process, and the distillery also employs slow, controlled fermentation to bring out fruity and citrusy qualities in its products.
The Tree Itself: Why Garry Oak Is Unlike Any Other Cooperage Wood
To understand what makes the Garryana series distinctive, you first need to understand what makes the tree itself unusual. The broadleaf hardwood was named in 1839 and offered little commercial value, according to 1920s U.S. Forest Service literature, though the species was noted for making good barrel staves, which were likely used to make beer barrels in the region. For most of the 20th century, the wood remained outside the whiskey industry's orbit entirely.
What the wood does to spirit inside a cask is where things get genuinely interesting. Unlike its favored cousin American oak (Quercus alba), Garryana imparts complex flavor notes like stick molasses, clove, smoke, ground coffee, and blackberry preserves — a vastly different profile when compared to the industry-standard American oak, with its more familiar notes of baking spices, caramel, and tropical coconut. The distinction isn't subtle. Side-by-side, the two oak species produce whiskey profiles so divergent they might as well belong to different traditions.
Garryana is prized for the specific flavors it imparts to whiskey, with a focus on notes of clove and molasses — and it contains no vanillin, interestingly, according to the Westland team. The absence of vanillin is significant: that compound is responsible for the sweet, creamy vanilla notes that American bourbon drinkers have come to expect as a baseline. Without it, Garry oak pushes whiskey in an entirely different direction — toward savory, tannic, darkly spiced territory that rewards contemplation rather than casual sipping.
On its website, Westland calls the wood's impact "spicy, savory, fierce, and tannic," and it tempers those bold flavors with the use of additional cask types, including sherry, rum, brandy, and ex-bourbon barrels. That blending philosophy — using multiple cooperage types to frame and soften the wood's more aggressive characteristics — is central to what makes each annual release a craft exercise rather than simply a novelty.
The Supply Challenge Behind the Bottle
Getting Garry oak into a whiskey cask isn't as simple as calling a cooperage. Due to human development, Garry oak grows in only five percent of its former habitat. It is already a hyper-local species, growing only in the lowlands between southern British Columbia and the northern borders of California. Because of this oak's relative scarcity, no commercial system has been built for its use, meaning Westland has had to create the infrastructure for supply from the ground up.
Owing to its relationships with coopers, Westland works to source this wood, which on average takes years to mature out in the elements. Compared with the traditional practice of taking 'green wood' and manufacturing a cask, Garryana needs considerable time to dry properly before it is ready for cooperage. This is not a wood species that can be rush-ordered from a major stave mill. Every cask filled with Garry oak represents a long chain of supply decisions made years — sometimes decades — in advance.
Given the relative supply considerations of this oak type, use of it from one release to another over the years has waxed and waned. The 2018 third edition, for example, saw limited supplies force the ratios of full-term Garry oak-matured casks to shift dramatically. In that third release, limited supplies forced the ratios of full-term matured Garry oak casks to traditional oak casks to vary more greatly than, say, the fifth edition from 2020, which had a higher percentage of Garry oak casks — 36% Virgin Quercus garryana with 64% first-fill ex-Bourbon — in the blend than any previous edition.
Eleven Years of Annual Releases: A Serial Story Told in Oak
Five years after its founding — a decade before American single malt became an official category — Westland launched its first Garryana whiskey, which aged a portion of its blend in Oregon white oak. The distillery had actually been filling Garry oak casks even earlier than that first release date might suggest. Going back into the history of Westland and its relationship with what's also known as Oregon oak, the distillery first began filling casks made from it back in 2011. That means the wood sitting in those early barrels had already been working on the spirit for several years before a single bottle reached a consumer's hands.
What followed was a series of releases that each used a slightly different configuration of cask types, proportions, and maturation lengths — a controlled experiment in how Garry oak interacts with different supporting woods and different amounts of time. Master Blender Shane Armstrong described the approach this way: "Each edition is iterative and exploratory — a valley between retrospection and progression." That framing captures something essential about the series: it is not a product line in the conventional sense, where consistency is the goal. It is more like an ongoing scientific and artistic investigation, with each release reflecting what the distillery has learned and what it wants to interrogate next.
Armstrong, who has led the Garryana series since its inception, has said, "There is a magic to working with an oak species unique to our region." That sentiment gets at why the series has resonated far beyond Seattle's craft spirits scene. There is something compelling about a distillery that treats its local environment — its actual geography, its native trees — as fundamental raw material rather than marketing backdrop.
Critical Recognition That Opened Doors
The series didn't stay a local secret for long. The eighth edition ranked #3 in Whisky Advocate's Top 20 Whiskies of 2023, a result that put the entire Garryana concept in front of an international audience overnight. Westland's Garryana single malt was placed third best in the world in that 2023 blind taste test conducted by Whisky Advocate magazine, making it the highest-ranked American whiskey that year — and signaling that the Pacific Northwest had arrived as a legitimate force in global whiskey production.
In 2024, Westland's Wine Cask Finish American Single Malt placed #20 on Whisky Advocate's Top 20 Whiskeys of 2024, marking the second consecutive year that the distillery was included in the publication's international rankings. Back-to-back appearances on that list — for different expressions — confirmed that Westland's critical standing wasn't a one-release fluke. The distillery had built something durable.
The Theft That Nearly Derailed Edition 10
The road to the 10th edition was not without drama. In July 2025, Westland Distillery was the victim of a sophisticated theft where a truck arrived at its Burlington, Washington warehouse with apparently valid documents and drove off with ten-year-old Garryana and other whiskeys worth at least $924,000. The incident was investigated by the Skagit County Sheriff in August and reported to the public in September.
Almost half of Westland's new Garryana American single malt was stolen, but the collectible whiskey launched last weekend regardless. The theft was a huge loss, particularly distressing to the team given that it was the oldest Garryana release to date, making the whiskey virtually irreplaceable. The episode underscored in dramatic fashion just how much the series had come to mean — both in financial terms and in cultural cachet. When criminals are willing to forge shipping documents and move fast to steal a specific limited-edition whiskey, that whiskey has clearly transcended hobby-level interest.
Despite everything, to mark a decade of Garryana in 2025, Westland also introduced a 10-year age statement to the annual bottling, which continues with the new 2026 release. That age statement wasn't just a marketing milestone — it represented a genuine commitment made eleven-plus years ago, when the distillery filled those first Garry oak casks and decided to leave them alone long enough to tell a meaningful story.
Edition 11: What's in the Bottle and Why It Matters
Edition 11 brings another significant shift: a return to cask strength, which hasn't been seen with this expression since the inaugural release in 2015. This year, the whiskey is bottled at an uncut 56.8% ABV. That decision is meaningful. Cask strength bottlings preserve everything the wood and time have done to the spirit — no dilution, no softening of edges. For a series defined by bold, spicy, tannic character, bottling at cask strength is essentially an invitation to experience Garry oak at its most uncompromising.
The final blend incorporates over thirty cask types — and for the first time ever in the series, beer casks appear among them. The beer cask inclusion is an intriguing development. Westland has a history of collaborating with Pacific Northwest breweries, and beer casks bring residual hop and grain character that interacts with malt-forward whiskey in ways that are genuinely unpredictable. It's a high-risk, high-reward blending decision, and the fact that it appears in a flagship release rather than a limited experiment suggests confidence in the outcome.
Bottled at cask strength, Garryana Edition 11 features rich, spicy aromatics. The oak introduces a unique expression of the Northwest terroir, and each release reveals a new facet of this rare oak's contribution to flavor. Given the beer cask addition and the return to cask strength, Edition 11 is shaping up as one of the most structurally adventurous releases in the series' run.
Garryana American Single Malt 11th Edition will be available at Westland's Seattle distillery starting November 7, with limited nationwide sales following later that month. Each 700ml bottle carries a suggested retail price of $149.99, and for 2026, the total release count is approximately 4,200 bottles. That is a notably small allocation — smaller than the 6,600 bottles of Edition 9 and the 7,380 bottles of Edition 8 — which will likely make secondary market activity brisk in the weeks following the release.
How Edition 11 Compares to Recent Predecessors
Each edition of Garryana builds on the accumulated knowledge of everything that came before it, and tracking the series across its eleven releases is instructive. Edition 8's tasting notes — new leather, brown sugar butter, dried rose, and plum on the nose, with brown bread, almond croissant, and semi-sweet chocolate on the palate — reflect the PX sherry cask influence that dominated that blend. Edition 9 swung toward a different kind of warmth: tasting notes of burnt marshmallow, biscuit, mocha, and almond cream on the nose, with ground clove, cinnamon stick, faint peppermint, and bread pudding on the palate, the product of a blend that leaned heavily on virgin Garryana oak and first-fill ex-Oloroso butt.
Edition 10 pushed into uncharted territory with its 10-year age statement. The whiskey opened with strong scents of red fruit, including strawberry and raspberry, before transitioning to a rich mix of fudge and walnut, and ending on pale malt and a hint of orange peel. The palate was no less complex, with notes of cocoa, clove, charred oak, graham cracker, and walnut creating a strong earthy undertone that the brand is known for. The mouthfeel was oily with a long finish, delivering brown sugar, oak, and a touch of smoke, with wonderful throughlines displaying the oak, sugars, and complex profiled finishing casks.
Against that backdrop, Edition 11's cask-strength bottling and first-ever beer cask inclusion represent a deliberate departure — a reset to the series' most elemental expression while simultaneously expanding its palette of ingredients. It's a bold move that will reward those who approach the bottle with curiosity rather than expectation.
The Trend Westland Sparked: Other Producers Moving Into Garryana Territory
While Westland's limited-edition single malt is likely the most famous Garryana whiskey on the market, it's not the only one making waves. Westland's success has inspired other companies to experiment with the same oak species, and the result is a new branch of flavor in American whiskey, one where distillers and blenders have only begun to scratch the surface.
The influence extends beyond distilleries that focus on single malt. Several American whiskey producers are leaning into Garryana oak, a Pacific Coast wood species that creates unique and spicy flavors. The broader whiskey industry — including producers working in styles far removed from single malt — has noticed that Garry oak can do things to a spirit that no other American wood can replicate. The question isn't whether Garryana will become a recognized flavor category; by most indications, it already has. The question is how many producers can sustainably source enough of a scarce wood species to make meaningful quantities of it.
It's tough to say exactly who first aged spirits in Garry oak, but distiller and writer Daniel Stewart traces the modern practice to Oregon Barrel Works founder Rick DeFerrari. One of DeFerrari's early customers was Clear Creek Distillery, an Oregon-based craft distillery that helped establish the Pacific Northwest's early craft spirits identity. The groundwork laid by those early experiments — before Westland was even founded — created the foundation on which the Garryana movement now stands.
American Single Malt's Institutional Moment and Westland's Role in It
Along the way, Westland has been recognized as the country's leading producer of American single malt whiskey and founded the formal establishment of the emerging American single malt whiskey category by starting the American Single Malt Whiskey Commission. That institutional work — lobbying for a legal definition, organizing producers, establishing standards — ran in parallel with the artistic work of making whiskey, and both efforts reinforced each other. The Commission's advocacy gave the category legitimacy; Westland's whiskey gave it credibility.
The Garryana series occupies a specific position within Westland's larger catalog. Westland's Outpost Range of American single malt whiskeys features three limited-edition expressions that are released annually — Garryana, Colere, and Solum. This specialized focus explores what's described as "Pacific Northwest Provenance," with these bottlings bringing to life the considerations of Pacific Northwest oak (Garryana), barley (Colere), and peat (Solum) on the development of unique variants of the distillery's whiskeys. Each arm of the Outpost Range isolates a different variable and interrogates it annually, which means the program as a whole functions almost like a long-running academic study of what Pacific Northwest terroir actually means in a glass.
Westland believes the Pacific Northwest is best suited to the curation of single malt whiskey over more popular styles like bourbon. The climate is heavily impacted by the Pacific Ocean and the Cascade Mountains, meaning temperatures never get too hot or too cold — especially compared to Kentucky, Colorado, or Tennessee. That climatic argument is more than marketing copy. Consistent, moderate temperatures mean slower, more even barrel interaction — whiskey that ages with subtlety rather than intensity, building complexity over years rather than forcing extraction in a hot summer warehouse.
What Edition 11 Signals for the Future of the Series
Eleven editions in, the Garryana series has demonstrated a rare quality in annual limited releases: genuine evolution. Most whiskey series that drop on a yearly basis eventually settle into a predictable formula, iterating on proportion rather than concept. Westland's series has consistently refused that comfort. Beer casks in Edition 11. A 10-year age statement debuted in Edition 10. Cask strength returning for the first time since Edition 1. These are not minor tweaks — they are fundamental reconceptions of what the whiskey can be.
The scarcity factor will only grow more complex. With only 3-5% of Garry oak's natural habitat remaining, Westland's goal is to preserve as much of this keystone species' habitat as possible in an effort to perpetuate the species and keep the ecosystem of the Pacific Northwest healthy. That conservation commitment has practical implications for the series' long-term trajectory. The distillery can't simply decide to scale up production dramatically — the wood isn't there to support it. Every bottle of Garryana is, in a sense, a product of the distillery's ability to manage an extraordinarily constrained supply chain while delivering consistent quality at a demanding level.
Seattle's Westland Distillery had been preparing for its milestone moment for over fifteen years, and the Garryana series illustrates exactly why American single malt is a critical part of American whiskey's future. The series is not just a celebration of Westland's groundbreaking use of native oak — it's a statement to the rest of the whiskey world that American single malt stands alongside Scotland, Japan, Ireland, and other major producers as a peer and a category leader.
For the whiskey enthusiast paying attention, the arrival of Edition 11 each November has become a reliable marker of the season — as anticipated as any annual release in American craft spirits. There's a snap in the air, football is back on the airwaves, farmers markets fill with more comforting fare, and Westland Distillery releases its latest edition of Garryana whiskey. That seasonal rhythm has built a kind of loyalty that no advertising campaign could manufacture. Edition 11, with its cask-strength delivery, its thirty-plus cooperage types, and its first-ever beer cask addition, is positioned to be among the most discussed releases in the series' history — and a compelling argument that the best chapter of the Garryana story may still be ahead.
