You’re standing in the warehouse. Your cart is already overflowing with a rotisserie chicken, a 30-pack of toilet paper, and a literal gallon of mayonnaise you didn’t know you needed until three minutes ago. Then you hit the spirits aisle. There it is—the frosted glass of a Grey Goose at Costco bottle, sitting right next to the towering, 1.75-liter monolith of Kirkland Signature French Vodka. One is roughly $50. The other is barely $20.
Your brain does the math. They’re both French. They both use wheat from the Picardy region. They both have that elegant, slender bottle neck.
So, you ask the question everyone asks: "Is Costco just rebottling the Goose?"
It’s a persistent urban legend. It’s the kind of thing people swear is true after two martinis. But the reality of how Grey Goose at Costco operates—and why the Kirkland version exists—is actually way more interesting than a simple private-label swap. Honestly, the liquor industry is built on secrets, but some secrets are easier to crack than others.
The Myth That Won't Die: Is Kirkland Actually Grey Goose?
Let’s kill the rumor immediately. No, Kirkland Signature French Vodka is not Grey Goose.
Joe McCanta, the Global Head of Education for Grey Goose, has gone on the record multiple times to shut this down. It’s a flat "no." They don’t produce private label spirits for anyone. Period. If you’re buying Grey Goose at Costco, you are buying the genuine article produced by Bacardi. If you buy the Kirkland bottle, you’re buying something else entirely.
But wait. Why do they taste so similar?
It comes down to geography and ingredients. Both spirits are produced in the "breadbasket of France." They both utilize soft winter wheat. They both use water that has been naturally filtered through limestone. Because the production methods for high-end French vodka are so regulated and specific, the flavor profiles naturally overlap. It’s like comparing two high-end sourdough loaves from the same neighborhood in San Francisco; they aren't the same bread, but they’re definitely cousins.
The "Grey Goose is Kirkland" theory gained massive traction because of a 2016 victory. In a blind taste test conducted by The Kitchn, the Kirkland bottle actually beat Grey Goose. When a $20 bottle beats a $50 legacy brand, people want to believe they’ve found a glitch in the Matrix.
The Economics of Buying Grey Goose at Costco
Why buy the name brand at all then?
Consistency is the big one. When you buy Grey Goose at Costco, you are paying for a specific, unchanging distillation process overseen by a Maître de Chai (Cellar Master). For Grey Goose, that’s François Thibault. He’s the guy who pioneered the idea that vodka could be a luxury product made from wheat rather than potatoes or rye.

Costco moves massive volume. Because of their "cost-plus" pricing model—where they generally don't mark up items more than 14 or 15 percent—the Grey Goose at Costco price is usually the lowest you’ll find in any retail environment. While a standard liquor store might charge a premium for that frosted bottle to cover their higher overhead, Costco treats it like any other commodity.
It’s a volume game.
They know you’re there for the deals, but they also know that some members won’t show up to a dinner party with a Kirkland bottle. Status matters. Branding matters. The "clink" of a Grey Goose bottle on a granite countertop has a specific social currency that a generic label simply hasn't earned yet, regardless of what's inside the glass.
Where the Water Comes From
Water is the soul of vodka. It’s 60% of what’s in the bottle.
Grey Goose uses water from a dedicated well in Gensac-la-Pallue. This water is naturally filtered through 500 feet of limestone. It’s pure. It’s soft. It gives the spirit that "fat" mouthfeel that makes it go down without the medicinal burn of cheaper spirits.
The Kirkland version also uses French spring water, but it’s not from the same source. This is the nuance people miss. Even if you use the same wheat, different water minerals change the final product. It’s subtle, but if you’re a purist drinking it neat, you’ll notice the Goose has a slightly creamier finish, whereas the Kirkland version tends to have a bit more of a "bright" or "citrusy" bite.
The Logistics of the Costco Liquor Aisle
Costco is the largest wine retailer in the world. Their spirits business is nearly as massive. This gives them incredible leverage. When they stock Grey Goose at Costco, they aren't just buying a few cases; they are buying entire shipping containers.
However, you might notice that not every Costco carries the Goose.
Liquor laws in the United States are a total mess of post-Prohibition era leftovers. Some states, like Texas, don’t allow "publicly traded" corporations to sell hard liquor. In others, Costco can only own a certain number of liquor licenses. If you live in a state like Utah or Pennsylvania, your Costco experience is going to be very different—and likely devoid of that sweet, sweet vodka aisle.
But for those in "wet" states like California, Florida, or Arizona, the spirits section is a goldmine. The price of Grey Goose at Costco typically hovers around $45 to $49 for a 1.75L handle. For context, a 750ml bottle (less than half the size) at a standard grocery store often costs $30 or more.

Identifying the Real Producer
If it's not Grey Goose, who is making the Costco brand?
While Costco is famously tight-lipped about their suppliers, most industry experts point toward Terressentia or Leetree. Specifically, the Kirkland French Vodka is often linked to the Gayant Distillery in France. This is a massive, high-quality operation. They have the scale to meet Costco's demands without sacrificing the "premium" feel.
Is it "better" than Grey Goose? That’s subjective.
Is it the "same"? No.
How to Get the Most Out of Your Purchase
If you’ve committed to the Grey Goose at Costco purchase, you’re likely looking for a specific experience. You want the smoothness. You want the brand recognition.
Don't bury it in sugary mixers.
Grey Goose is designed to be the star. If you’re making a vodka soda with a heavy squeeze of lime, you could honestly get away with the Kirkland brand and nobody would know. But if you are shaking up a classic Martini—dry, slightly dirty, maybe a twist—the nuances of the Grey Goose distillation process actually shine.
The wheat notes are delicate. There’s a hint of almond and black pepper. Cheap vodka just tastes like rubbing alcohol; Grey Goose tastes like the ingredients it came from.
Understanding the 1.75L Commitment
The biggest "risk" of buying Grey Goose at Costco is the size. That 1.75-liter bottle is a beast. It doesn't fit in most standard liquor cabinets. It definitely doesn't fit in a freezer unless you remove a few bags of frozen peas first.
Before you buy, make sure you have a plan for storage. Large bottles are great for parties, but for daily use, they are cumbersome. Pro tip: Decant some into a smaller 750ml bottle for your home bar. It’s easier to pour, and you won't risk dropping a five-pound glass bottle every time you want a drink.

Common Misconceptions About Costco Liquor
People think because it’s a warehouse, the quality might be "seconds" or "misfits."
That's a myth.
The Grey Goose at Costco is the exact same liquid found at the most expensive bars in Manhattan. Bacardi (the parent company) would never risk their brand reputation by selling an inferior batch to their biggest customer. In fact, large retailers often get the freshest stock because their inventory turns over so quickly.
Another weird thing? You don't always need a membership.
In about 14 states—including California, New York, and Texas—state law prohibits stores from requiring a membership for the purchase of alcohol. You can literally walk up to the entrance, tell the attendant you are only there for liquor, and they have to let you in. You won't get the rotisserie chicken, but you'll get your Grey Goose at Costco at the member price. Check your local state laws before you try this, though, or you might end up in an awkward standoff with a guy in a red vest.
The Actionable Verdict
If you are a label-conscious host or someone who truly appreciates the specific, creamy mouthfeel of French wheat vodka, buying Grey Goose at Costco is the smartest way to source it. You're getting the lowest possible retail markup on a world-class spirit.
However, if you are mixing drinks for a crowd or making "punch," the Kirkland Signature French Vodka is the better value. It offers 90% of the quality for 40% of the price.
Next Steps for Your Next Warehouse Trip:
- Check the Origin: Look at the back of the bottle. Genuine Grey Goose will always list Gensac-la-Pallue.
- Verify the Volume: Ensure you’re looking at the 1.75L price tag when comparing to other stores; people often compare the Costco 1.75L price to a 1L price elsewhere and get confused.
- Temperature Matters: If you buy the Goose, store it in the freezer. High-quality wheat vodka becomes slightly syrupy when chilled, enhancing the texture.
- The "Hack": If you live in a "non-membership liquor" state, use the side entrance or the dedicated liquor pod to save the $60 membership fee.
Buying spirits in bulk isn't just about saving money; it's about having the right tool for the right occasion. Whether you choose the brand name or the store brand, the "Costco Vodka" aisle remains one of the few places in the grocery world where you can actually get luxury quality without the luxury tax. Just make sure you have room in the freezer.
