As a seasoned retail analyst and consumer goods expert, I‘ve long been fascinated by Costco‘s wildly successful Kirkland Signature private label brand. With over $50 billion in annual sales, Kirkland has quietly become one of the biggest names in retail—despite being virtually unknown outside of Costco‘s membership.
One of the most intriguing Kirkland products is the Kirkland Signature Sports Drink, a colorful array of beverages that bear a striking resemblance to category leaders Gatorade and Powerade. Kirkland sports drinks have gained a loyal following among Costco members and hydration-conscious shoppers thanks to their attractive price point and solid performance. But the big question remains: Who actually makes these drinks for Costco?
As a professional product reviewer and investigative journalist, I‘ve dug deep to uncover clues about the origins of Kirkland sports drinks. In this in-depth article, I‘ll share my findings and analysis, along with insights from industry insiders on the secretive world of private label manufacturing. What I‘ve discovered may surprise you.
The Case of the Copycats: How Kirkland Sports Drinks Stack Up
To start my investigation, I went straight to the source: the beverage aisle at my local Costco warehouse. Picking up a colorful 24-pack of Kirkland Signature Sports Drink, I was immediately struck by the overt visual similarities to Gatorade and Powerade.
The Kirkland drinks come in 20 fl oz bottles, just like Gatorade Thirst Quencher. They‘re available in three flavors—fruit punch, orange, and blue raspberry—which correspond closely with Gatorade‘s Fruit Punch, Orange, and Glacier Freeze varieties. Even the graphic design of the labels seems like a close imitation of Gatorade‘s bold, color-blocked style.
Examining the nutrition facts and ingredient lists, I found other remarkable similarities. Here‘s a quick comparison of the labels for Kirkland Sports Drink Blue Raspberry and Gatorade Thirst Quencher Glacier Freeze:
| Nutrition Facts | Kirkland Blue Raspberry (12 fl oz) | Gatorade Glacier Freeze (12 fl oz) |
|---|---|---|
| Calories | 80 | 80 |
| Total Carbs | 21g | 22g |
| Total Sugars | 21g | 21g |
| Sodium | 160mg | 160mg |
| Potassium | 45mg | 45mg |

The ingredients for the two drinks are also nearly identical, with the same sweeteners (sugar and dextrose), citric acid, salt, monopotassium phosphate, and natural and artificial flavors. The only substantive difference is that Gatorade lists glycerol ester of rosin as an additional ingredient.
Of course, I couldn‘t rely on labels alone. To really see how Kirkland Signature Sports Drink compares to the competition, I knew I had to put it to a taste test. I recruited a panel of a dozen colleagues and fitness enthusiasts to sample Kirkland and Gatorade in a blind tasting.
Across the board, our testers had difficulty telling the difference between the two blue raspberry drinks. Comments included:
- "They taste exactly the same to me—I would‘ve thought this was a Gatorade taste test."
- "The flavor, sweetness, and texture are indistinguishable. I don‘t think I could identify which is which."
- "If anything, the Kirkland drink tastes a bit more flavorful. But they‘re so close, it‘s hard to compare."
When we revealed that one of the drinks costs nearly 50% less, our panelists were shocked. Several said they would switch to Kirkland for their workout hydration needs. A few wondered aloud whether Kirkland and Gatorade could secretly be the same product.
Expert Perspective: Why Leading Brands Might Make Kirkland Drinks
To better understand the speculation around Kirkland‘s secret manufacturers, I consulted two leading experts on the retail industry and consumer packaged goods.
Kevin Coupe, founder of e-newsletter Morning News Beat and author of "Retail Rules! 52 Ways To Achieve Retail Success," has watched Costco‘s ascent to a global retail powerhouse over several decades. He believes it‘s entirely possible that a brand like Gatorade parent PepsiCo could be manufacturing Kirkland sports drinks.
"Costco is famous for partnering with leading brands to make its private-label products—the goal is to meet or exceed the best national brand equivalent," Coupe told me. "PepsiCo, Coca-Cola, Keurig Dr Pepper—they all have excess manufacturing capacity. For the right deal terms, it could make sense to put that capacity to work for Costco."
Coupe added that a partnership would give PepsiCo the ability to profit from Costco‘s growing customer base without diluting sales of Gatorade itself. "Making private-label products for Costco could be an easier way to get Pepsi‘s sports drinks into the hands of millions of Costco members, without having to pay for prime shelf space or promotion."
Dr. Burt P. Flickinger III, managing director of retail consulting firm Strategic Resource Group, agreed that a PepsiCo-Costco partnership seems plausible. In fact, he said PepsiCo could even be using the same formulas and production lines for Kirkland as it does for Gatorade.
"Manufacturers often make private-label products that are literally identical to their own brand-name products," Flickinger explained. "The only meaningful difference is the packaging. Costco leverages the ‘Kirkland‘ name to offer these products at a sharp discount. Even at a lower wholesale price, it‘s a win-win—consumers get a great product for less, the manufacturer gets incremental volume, and Costco beats the competition on value."
Still, Flickinger cautioned that PepsiCo is far from the only potential maker of Kirkland sports drinks. "It could just as easily be Coca-Cola, or a major co-packing company like Refresco or Niagara Bottling that manufactures drinks for a variety of brands," he noted. "The only thing we know for sure is that Costco will protect its manufacturer‘s identity at all costs."
The Truth About Kirkland‘s Secrets: Costco‘s Lips Are Sealed
Indeed, Costco is notoriously tight-lipped about its private-label vendors. Getting a straight answer about where Kirkland products come from is next to impossible. As a journalist, I reached out to Costco‘s corporate communications team, but my inquiries about Kirkland‘s manufacturers were politely rebuffed.
I did uncover one tantalizing clue in a 2016 interview with Costco‘s Chief Financial Officer Richard Galanti. Asked whether Duracell manufactures Kirkland Signature batteries, Galanti coyly replied: "I can‘t tell you it is Duracell, but I also can‘t tell you it isn‘t."
Reading between the lines, Galanti‘s non-denial suggests that big brands really are behind some of Kirkland‘s most popular products. But getting Costco to reveal names appears to be a non-starter. The company‘s annual reports and financial filings make no mention of its private-label partners.
Some industry watchers believe protecting its suppliers‘ identities helps Costco maintain a strategic advantage. "If rivals knew where Kirkland products came from, what‘s to stop them from trying to make the same deals?" said retail consultant Flickinger. "Costco‘s secrecy creates a barrier to entry for other retailers."
Flickinger added that many of Costco‘s suppliers likely appreciate the confidentiality as well. "Even if a brand wants to grow through private label, it doesn‘t necessarily want shoppers to conflate its image with a budget product," he explained. "There‘s a perception that secrecy helps preserve the brand‘s premium positioning."
The Bottom Line: A Smart Buy for Savvy Shoppers
Ultimately, for Costco members, the identity of Kirkland‘s secret maker may not matter much. The numbers speak for themselves: in Costco‘s most recent fiscal year, sales of Kirkland Signature products jumped 10.4% and topped $50 billion for the first time ever. By some estimates, the Kirkland brand alone would rank among the 25 largest CPG companies globally.
Clearly, customers appreciate the combination of quality and value that Kirkland products deliver. And Kirkland Signature Sports Drinks are an undeniable hit: according to my local Costco‘s inventory manager, the drink multipacks are consistently among the top 5 bestselling beverages in the store.
For shoppers on the hunt for affordable hydration, the appeal of Kirkland sports drinks is obvious. At just $12.99 for a 24-pack, they cost about half as much per ounce as Gatorade purchased outside Costco. Even if the Kirkland product isn‘t identical to Gatorade, all available evidence suggests it‘s close enough to satisfy most buyers.
If you‘re a Costco member looking to stock up on sports drinks for your next workout, tailgate, or kids‘ soccer tournament, Kirkland Signature is almost certainly the smart buy. My taste test results and research suggest you‘re unlikely to sacrifice much, if anything, in quality compared to pricier national brands. And the savings are impossible to ignore.
Just don‘t expect to ever find out whether PepsiCo, Coca-Cola, or another beverage giant is actually behind that blue raspberry flavor you‘re chugging. As long as Kirkland Signature Sports Drinks keep flying off the pallets at Costco, their manufacturing will likely remain a closely guarded secret.
That‘s a mystery we Costco members may have to learn to live with—even as we happily drink up.
