Inside the Decade-Long Bet That Built the World's First Andean Single Malt Whisky
In 2013, two Argentine brothers drove into the wine country of Mendoza with a plan that sounded, to most people in the spirits world, somewhere between ambitious and reckless. When brothers Cristian and Gabriel Williams began building a whisky distillery in Mendoza, Argentina in 2013, they had no established regional model to follow—and no guarantee that the project would ever produce a sellable bottle. The country had world-class Malbec. It had centuries of winemaking tradition rooted in immigrant European culture. What it did not have was a single malt whisky of its own — and certainly not one built from the ground up using Andean terroir as its core philosophy. More than a decade later, those two brothers have not only produced that whisky, they've staked a claim to something bigger: the creation of an entirely new category.
More than a decade later, Williams Casanegra Distillery is releasing limited quantities of single malt shaped by high-altitude barley, glacier-fed water, historic equipment and an unusually stubborn commitment to patience. That commitment is not a marketing line. It is, by any measure, the story of this distillery — a project defined not by its speed to market but by a willingness to let years pass, to keep tasting, and to keep waiting until the whisky was ready on its own terms.
Where the Idea Took Root
In a province where wine seems to define the culture, Gabriel and Cristian Williams asked themselves an inevitable question: "Why not produce a whisky that represents the Andes?" That curiosity — born within a family deeply rooted in whisky-drinking traditions — became the starting point for the brothers, partners, and whisky makers. The question is deceptively simple. The execution was anything but.
Mendoza sits at the eastern base of the Andes in Argentina's Cuyo region. It is, first and foremost, wine country — one of the great viticultural zones on the planet, known internationally for high-altitude Malbec that has found a devoted following among American collectors. But far from the traditional whisky maps, Mendoza has begun writing its own story. At the foot of the Andes, where wine shaped the region's identity for decades, another industry is now emerging — one that seeks to express the province's terroir and unique production conditions.
The Williams brothers grew up in that wine culture but were drawn to whisky — the complexity of its production, the patience it demands, and the way the finest expressions of it are inseparable from the places they come from. Rather than replicating classic styles, their goal was to create something entirely their own: a malt with Andean identity, shaped by altitude, a dry continental climate, and glacial meltwater. That philosophy — terrain over tradition, place over precedent — became the organizing logic of everything Williams Casanegra would eventually build.
The Terroir: High, Cold, and Extreme
Barley at Altitude
For any serious whisky producer, grain is everything. It is the raw material that, in a single malt, accounts for the entirety of the fermentable sugar — and, by extension, much of the flavor potential that no amount of cask management can invent after the fact. The Williams brothers understood this from the beginning, which is why the barley they use is grown not in some agricultural flatland but deep in the mountain valleys where conditions are genuinely extreme.
They planted barley in the Uco Valley of the Andes Mountains, at elevations between approximately 1,500 and 2,500 meters, where strong sunlight, cold temperatures and dramatic shifts between day and night shape the crop. This diurnal temperature variation — the swing between scorching afternoon sun and near-freezing nighttime cold — is the same force that concentrates flavor compounds in Malbec grapes grown at altitude in the same valley. Applied to barley, it creates a crop with a different metabolic fingerprint than what you'd find growing at sea level in Scotland or Kentucky. Cristian remembers finding the land to grow their barley in the Andes. "We felt an inexplicable connection," Cristian recalls. "With our hearts guiding us, we decided to plant barley here — in this wild and extreme terroir."
Glacier Water and Native Yeast
Water is the other foundational ingredient in any whisky, and Casanegra's source is as pure and as geographically specific as any in the world. Water comes from Andean snow and glacier-fed waterways. That glacial meltwater carries a mineral profile that is inseparable from the mountain system that created it — a characteristic that becomes part of the whisky's molecular identity at every stage of production, from mashing through to dilution before bottling.
But the brothers pushed the concept of local terroir even further. The distillery also says it gathers native yeasts from its barley fields, using the surrounding environment to help define the whisky from its earliest stages. This is a decision that very few distilleries in the world make, and it carries real risk. Wild and native yeast fermentations are less predictable than commercially cultivated strains. They are harder to control, more variable from batch to batch, and more susceptible to contamination. But they also carry the biochemical signature of their specific location — the microbial life of the Andean foothills encoded in every fermentation. For a distillery committed to creating something that tastes like nowhere else on Earth, that unpredictability is a feature, not a flaw.
The Distillery: Built from Argentina's Industrial Memory
The Williams Casanegra operation is not just defined by its ingredients. The physical space itself is a statement — and a deeply considered one. Nestled at the foothills of the Andes, in the prestigious wine micro-region of Las Compuertas, Luján de Cuyo, the Williams Casanegra Distillery masterfully bridges Mendoza's winemaking heritage with the refined art of craft distillation. The address may be in one of Mendoza's most famous sub-zones, but the building itself reads like a museum of Argentine industrial history.
Just as distinctive is the distillery itself, located in the Andean foothills of Luján de Cuyo, Las Compuertas. The brothers spent years constructing it with salvaged materials collected from century-old wineries, the Argentine railway and a former Cinzano facility. Every beam, stone, and piece of metalwork carries the weight of that history. Designed with a deep commitment to sustainability and cultural preservation, the architecture of The Williams Casanegra revives the essence of Argentina's industrial and immigrant heritage. Every structural element — wood, copper, stone, burnt brick, and recycled metal — was recovered from emblematic 20th-century Argentine industries.
Equipment with a Century of History
The equipment inside the distillery is as historically rooted as the walls. Cooking, fermentation and distillation equipment made largely from copper is more than a century old. A clay malting oven incorporates historic adobe bricks, while an in-house cooperage allows craftspeople to restore, toast, and maintain barrels on-site. The decision to use a clay malting oven is particularly significant: it is a method associated with old-world craft production, one that imparts subtle earthen and smoky character to the malt that modern industrial kilns simply cannot replicate.
Having an in-house cooperage is a rarity even among elite distilleries in Scotland and the United States. Most distillers buy their barrels from external cooperages and have limited ability to customize the toasting or manage repairs to their specifications. At Casanegra, barrel management is an internal craft — barrels can be restored, re-toasted, and maintained on their terms, giving the brothers precise control over one of the most powerful variables in any aged spirit.
The Casks: Mendoza's Wine Heritage Poured Into Whisky
One of the most compelling aspects of Casanegra's approach to maturation is the decision to use barrels drawn directly from Mendoza's wine industry — a move that connects the whisky to the region's most deeply established tradition. The result is Casanegra Andes Single Malt, a whisky that stands apart through its connection to the Mendocinian landscape — from barley grown at altitude in the Valle de Uco to the use of barrels sourced from some of Mendoza's most renowned wineries, which influence the maturation profile. Chardonnay and Semillón casks, for example, leave their mark on the aging process, weaving the region's winemaking heritage into every bottle.
The logic behind using freshly emptied wine barrels goes beyond romanticism. Casks previously used for regional bottlings give Casanegra access to maturation vessels that remain closely tied to Mendoza. Because the barrels can arrive freshly emptied, they retain aromatic and flavor compounds, and other releases have drawn on rare Cognac pipes, including French oak vessels dating to the 1960s. The contrast between these two extremes — freshly emptied contemporary Chardonnay casks and 60-year-old Cognac pipes — speaks to a maturation philosophy that prizes diversity and complexity over formula. There is no single Casanegra house style born of a single barrel type; instead, each release is a conversation between the spirit and whatever vessel the brothers have determined will complete it best.
The Résistance Collection
That philosophy finds its most extraordinary expression in the distillery's most premium release. The Résistance Collection ages in rare 1968 XXO Cognac pipes for ten years. A ten-year maturation in 1968 Cognac pipes is not the kind of thing that gets decided in a quarterly strategy meeting. It is the product of long-term thinking — of acquiring extraordinary old vessels, filling them carefully, and then having the discipline to leave them alone until the whisky inside has become something worth releasing. It is, in its own way, the perfect distillation of what the Williams brothers have been doing since 2013.
A Decade of Not Selling Anything
The Financial Reality of Patience
The romantic image of two brothers waiting patiently for their whisky to mature glosses over the brutal economic reality of what they actually endured. They waited about a decade for the first release — costs mounting, revenue at zero. For two entrepreneurs and brothers, that sort of stress could have broken the brand and them. Building a distillery, sourcing rare equipment, acquiring aged barrels, employing staff, and maintaining operations for more than ten years without meaningful product revenue is a financial undertaking that most business plans would never survive. The whisky industry, particularly for new single malt producers, demands capital that precedes income by years. At the scale and with the philosophy that Casanegra operates, a decade is not unusual — but it is still genuinely brutal.
The pressure was compounded by the nature of the decisions the brothers were making. But the project's defining ingredient may be time. For years, the brothers tasted their whisky and decided against releasing it. "Spending the entire day in the warehouse tasting whiskies and deciding not to release any because they'll be better next year — and having that happen every single year," Gabriel says, describing the experience of building the company together. That kind of discipline — repeatedly choosing not to sell when a lesser producer would have moved product to recover costs — is remarkable. It also speaks to something beyond commercial calculation: a conviction that what they were making had to be right before it could be released, regardless of what the balance sheet said.
Building Revenue Bridges
While the single malt matured in its barrels and the brothers kept saying no to premature releases, they were not entirely without an income-generating operation. The distillery produces an exceptional collection of wine-based spirits — including grappa, varietal brandies, pisco, lees eaux-de-vie, and vermouths — some developed in collaboration with the region's most renowned wineries. Under the Andina Compañía Destilera label, they were building expertise, industry relationships, and some measure of cash flow while the whisky they actually cared about most continued its unhurried development in the warehouse.
This parallel operation served another strategic purpose: it let the brothers develop their in-house cooperage skills, learn the properties of various barrel types, and conduct a kind of shadow maturation program by aging other spirits — including calvados, brandy, and pisco — specifically so that those used barrels could later be deployed for whisky finishing. In that sense, every bottle of pisco or brandy they sold was also an investment in the future whisky program, seasoning barrels that would eventually hold Casanegra.
Recognition and the Emerging Category
The outside world is beginning to take notice. Casanegra Andes Single Malt was named a finalist for Best Argentine Distillate at the 2026 Winexplorers Awards, an early indication of its growing visibility within Argentina's spirits community. For a distillery that spent the better part of a decade operating in near-total obscurity, that recognition carries genuine weight.
More importantly, the distillery is staking a claim that goes beyond any single award. It created the world's first Andes Single Malt, made entirely with resources sourced from the Andes and aged in barrels that once held Mendoza's finest wines. That is not a modest claim, but it is a defensible one. That's the key element in their whisky — the Andean terroir. Since Casanegra is the first whisky ever made there, it is defining the region. When there is no precedent, the first serious producer becomes the standard — for better and for worse. Everything that comes after will be compared to what Casanegra established.
The Experience: Chupacabras and the Whisky Lifestyle
The brothers have not been content to simply make whisky and sell bottles. They've built an entire experiential ecosystem around the distillery, anchored by a space that functions as both a brand showcase and a destination in its own right. Inside the distillery — and serving as the first stop for visitors — is Chupacabras Whisky Boutique & Club, a space that captures the spirit of the house through an intimate and immersive atmosphere where mountain aesthetics meet contemporary design.
Wood, fire, textures, and dim lighting create an environment that encourages visitors to slow down and stay awhile. The Chupacabras experience is not the typical tasting room setup of a production-first facility. It is a deliberately crafted environment designed to slow people down and let them inhabit the whisky world that the brothers have spent over a decade building. Experiences range from guided tours to curated tastings of different Andes Single Malt expressions, often paired with specially designed food pairings. Among them is a selection of artisanal cheeses chosen to complement and amplify the whisky's notes and complexity. For those who want to push further, there are also lunches and dinners and, for those seeking an even more leisurely experience, a dedicated Cigar Lounge featuring a curated cigar selection.
The visit itself is structured as a journey through the full production process. With personalized visits, tours through its "productive village," and curated tastings, the distillery opens its doors to an experience where whisky also becomes a way of exploring and understanding the Andes. That framing — whisky as a lens for understanding a mountain range and a culture — is the kind of positioning that resonates well beyond the spirits market. It speaks to the same audience that travels to Scotland not just to taste whisky but to stand inside the stone buildings where it is made and feel the weight of that tradition.
What This Means for the Global Single Malt World
The New Geography of Whisky
The global single malt category has been expanding geographically for years. Producers in Taiwan, India, Japan, Australia, and Scandinavia have each proven that exceptional single malt whisky is not the exclusive province of Scotland — or, for that matter, of any particular hemisphere or climate. What Casanegra adds to this story is a producer working at genuine altitude, in a wine-dominated culture, with a radical commitment to local raw materials that goes all the way down to the yeast.
American whiskey drinkers who have followed the growth of craft distilling in the United States over the last fifteen years will recognize the underlying logic: the best producers are the ones who make specific, place-rooted decisions rather than trying to approximate the flavors of more established traditions. The distilleries that endure are the ones that know why they are different and commit to that difference from the ground up. Casanegra's commitment to Andean barley, glacier water, native yeast, and Mendocinian wine barrels is exactly that kind of foundational specificity.
The Terroir Argument Comes to Whisky
For decades, the wine world has organized itself around the concept of terroir — the idea that the specific combination of soil, climate, elevation, and biological environment in a given place produces flavors that cannot be replicated elsewhere. The whisky industry has historically been more resistant to this framing, in part because the dominant producing nations have relied on consistent production methods that deliberately minimize batch-to-batch variation.
What the Williams brothers are doing is essentially importing the terroir argument into single malt whisky, and doing so with a level of conviction that goes further than most whisky producers anywhere in the world. Behind each expression is a commitment to crafting an artisanal spirit with complete traceability and a strong sense of identity. Here, time itself becomes part of the value. Complete traceability — knowing exactly where the barley was grown, what water was used, which yeast fermented it, and which barrel aged it — is the single malt equivalent of a wine estate bottling. It is the fullest possible expression of origin, and it is the direction that the most ambitious tier of the global spirits market is moving.
The Bigger Picture: An Andean Identity Still Being Written
Casanegra is now attempting something larger than producing an Argentine whisky. Through altitude, local ingredients, reclaimed materials, reused casks and long maturation, the brothers are defining what an Andean single malt might become — and proving that sometimes the most ambitious business strategy is refusing to rush.
That last point deserves to sit with American whiskey drinkers for a moment. The domestic craft distilling industry has produced some remarkable spirits, but it has also produced an enormous volume of product that was released too young, aged in undersized barrels to artificially accelerate maturation, or marketed with a terroir story that the liquid itself couldn't back up. The discipline that Cristian and Gabriel Williams exercised — spending years walking into their own warehouse and walking out again without releasing a single bottle — is the kind of long-view thinking that built the great whisky traditions of Scotland and Ireland over centuries. It is rare. It is increasingly valuable. And in an era when consumers are paying serious attention to provenance, authenticity, and the actual decisions that distillers make, it is exactly what separates a brand worth following from one that is simply filling a shelf.
The Williams brothers did not just build a distillery in Mendoza. They built an argument — that the Andes can produce whisky as specific, as serious, and as worth drinking as anything coming out of the established producing nations. With their first limited releases finally in the world, that argument is now something anyone can taste for themselves.
