Who Really Makes Kirkland Wine and Spirits at Costco?
Costco is the largest wine retailer in America by volume. It is almost certainly the largest retailer of whiskey in North America. Its Kirkland Signature alcohol program generated over $5 billion in sales in 2020, and the numbers have only grown since. And yet the bottles on those warehouse shelves — the $18 Chablis Premier Cru, the $30 Single Barrel Bourbon, the $8 Malbec from Mendoza — carry no winery name, no distillery address, and no explanation of who actually made them. That is by design. Costco keeps its supplier relationships confidential to protect its pricing power and maintain what it calls “the best possible price for our members.” But wine writers, spirits journalists, government import records, and the occasional label that breaks the rule have revealed more than Costco might prefer. The story behind the Kirkland label is more interesting than the label suggests — and it connects directly to the most significant trends in wine and spirits right now: the bourbon glut, the European winery cash crunch, and the rise of private label as the smartest value play in the drinks world.
The Wine — Who’s Actually Making It
Costco began its private label wine program in 2003. Twenty years later it sells more wine by volume than any other single retailer in America. The program works because Costco brings something most retailers cannot: guaranteed volume purchases, cash payment, and a member base that will actually drink the wine rather than keep it for status. For a producer who needs to move product, that is enormously attractive.
What has surprised wine journalists who have investigated the sourcing is not that Costco uses established producers — it is how good those producers are. The Alcohol and Tobacco Tax and Trade Bureau’s public registry, label approvals, and the occasional producer who simply volunteers the information have revealed a roster that reads like a who’s who of quality-focused winemaking.
Why Smaller Vineyards Say Yes to Costco
The question of why established and respected producers make wine under the Kirkland label — rather than their own — has a straightforward economic answer. Costco purchases in volume, pays promptly, and requires no marketing investment from the producer. A winery that might sell 5,000 cases of its own label wine through a distributor network over twelve months can sell that same volume to Costco in a single purchase order. The tradeoff is price — Costco’s buying power means the producer accepts a lower per-bottle margin. But lower margin on guaranteed volume, paid quickly, is often better than higher margin on uncertain volume that might sit in a warehouse for months. The 2026 bulk wine market data confirms this: the number of private label sellers at the Unified Wine & Grape Symposium increased dramatically as producers across Europe and California sought guaranteed-volume buyers to manage cash flow in a softening market.
The Bourbon — Barton 1792 and the Glut That Created the Opportunity
The bourbon on Costco’s shelves is the most straightforward story in the Kirkland program: it says right on the label who made it. The Kirkland Signature Bottled-in-Bond, Small Batch, and Single Barrel bourbons are produced at Barton 1792 Distillery in Bardstown, Kentucky — the oldest continuously operating distillery in Bardstown, operating since 1879 and owned by the Sazerac Company (which also owns Buffalo Trace).
The Kirkland Single Barrel has become a cult product. At 120 proof and approximately $30, it competes with bourbons retailing at $60 or more. Bourbon enthusiasts have documented consistent quality across multiple barrel selections, and the value proposition is genuine — not a budget product dressed up in warehouse packaging, but a well-made Kentucky straight bourbon at a price that reflects Costco’s buying power rather than the product’s actual quality tier.
The context that makes the bourbon story especially interesting in 2026 is the state of the broader industry. American distilleries — particularly in Kentucky — expanded production aggressively between 2018 and 2022, building new rickhouses and filling barrels in anticipation of continued demand growth. That demand growth has not materialized. Of the nine American whiskey brands selling more than one million cases per year, only Bulleit showed growth in 2025, with the remaining either level or in decline. Jack Daniel’s, the largest American whiskey brand, lost more than a million cases in a single year. Barrel inventories across Kentucky distilleries are at historically high levels as production decisions made between 2018 and 2022 meet a very different consumer environment.
That oversupply creates a buyer’s market for private label partners. Costco is most likely the largest retailer of whiskey in North America, and of the 50 spirit expressions the retailer offers, 20 are private label. For a distillery managing excess inventory, a Costco purchase order — large volume, reliable payment, no marketing cost — is a meaningful outlet. The bourbon glut does not mean the bourbon is lower quality; it means the market conditions that produced Barton 1792’s relationship with Costco are likely to deepen as distilleries seek volume buyers.
The Scotch — Alexander Murray and the Independent Bottler Model
Costco’s Kirkland Signature Scotch bottles openly credit the company behind them: Alexander Murray & Company, which has worked with Kirkland since 2007. Alexander Murray is an independent bottler — a category with a long history in Scotch whisky, where companies purchase aged whisky from distilleries, blend or select single casks, and bottle under their own or their clients’ labels.
In addition to Costco, Alexander Murray is also responsible for Trader Joe’s high-quality, yet affordably priced, Highland Scotch — making it the behind-the-scenes producer of two of the best-value Scotch programs in American retail simultaneously. Each bottle of Kirkland Scotch includes descriptors for region (Speyside, Islay, Highland), barrel type, aging duration, and ABV. The Islay Single Malt in particular earns strong reviews from Scotch enthusiasts who compare it favorably to single malts costing significantly more.
The independent bottler model works because Scottish distilleries produce more whisky than they can sell under their own labels, and the excess goes to blenders and independent bottlers who purchase it in casks and sell it through alternate channels. Costco, via Alexander Murray, is one of the most direct examples of how this system delivers quality Scotch to consumers at prices that the distillery’s own retail operations would not support.
The Rest of the Lineup — Vodka, Gin, Irish Whiskey, and Tequila
The CrushBrew Verdict — What to Buy and Why It Matters
The Kirkland Signature alcohol program is not a collection of budget products in premium packaging. At its best — and it is often at its best — it is a direct pipeline from legitimate producers to Costco members at prices that reflect buying power rather than marketing costs. The wine program in particular delivers genuine quality from genuine producers: Provence rosé from an 18th-century Sumeire chateau, Premier Cru Chablis from Jean-Marc Brocard’s winemaker, Châteauneuf-du-Pape from one of the Southern Rhône’s most respected hands.
The connection to larger industry trends is real. The bourbon glut has made distilleries more receptive to private label volume agreements. The European wine market softening has made smaller producers more willing to accept Costco’s terms in exchange for guaranteed cash flow. The bulk wine and spirits market in 2026 is a buyer’s market, and Costco is one of the most powerful buyers in the world.
The CrushBrew Buy List at Costco
Buy without hesitation: Kirkland French Vodka (Grey Goose’s distillery, one-third the price). Kirkland Single Barrel Bourbon (Barton 1792, 120 proof, ~$30). Kirkland Chablis Premier Cru (Jean-Marc Brocard’s winemaker, ~$19 vs $43 for the producer’s own label). Kirkland Châteauneuf-du-Pape (Guillaume Gonnet, Southern Rhône royalty). Kirkland Côtes de Provence Rosé (Olivier Sumeire, 18th-century Provence producer). Kirkland Islay Single Malt Scotch (Alexander Murray, genuinely good at the price).
Buy if the price is right: Kirkland Malbec from Mendoza (~$8, Broquel producer). Kirkland Rioja Reserva (genuine DOCa wine at warehouse pricing). Kirkland Small Batch Bourbon (solid, though Single Barrel is the better value).
Skip the Kirkland label and buy branded: Tequila (spend the difference on Don Julio or Patrón at Costco institutional pricing). Gin (Hendrick’s or Tanqueray at Costco beats the Kirkland house expression). Canadian Whisky (the sourcing is unclear and the quality is inconsistent).
The Kirkland label is not magic. It is a negotiating position — the leverage that comes from being the largest wine and whiskey retailer in North America, purchasing in quantities that most retailers cannot approach, and passing the resulting savings directly to members. Understanding who is actually making the wine and spirits inside those bottles does not diminish the value. It enhances it. You are not drinking a generic product. You are drinking Provence rosé from a producer whose chateau has been making wine since the 1700s, or Kentucky straight bourbon from the oldest continuously operating distillery in Bardstown, at a price that the producer’s own label cannot compete with. That is a good deal by any measure.
