What is Kirkland Signature?

Most brands usually stick to what they’re good at and stay in that genre. Lays has created some of the best chips in the world. Oreo has made some of the best cookies. And Heinz specializes in condiments. 

For Kirkland Signature, though, you can purchase their wine and dog food in one run. So what is this brand and why is it so big in Costco? 

Kirkland Signature is Costco’s private label and has been around for more than two decades. But it wasn’t always this popular. When Costco first popped up around the US, it carried more brand names than Kirkland Signature, but over time, it slowly incorporated more of its label into the retailer. 

Reasons to Shop Kirkland Signature Brand?

Not sure if you want to change from your favorite brands to Kirkland Signature? There are several reasons why picking Kirkland Signature can benefit you. 

The biggest reason is that it’s at a discounted rate compared to the other popular brands without skimping on quality. Most shoppers would rather pay an extra dollar or so to get high-quality products from popular brands. However, with Kirkland Signature, you can be comforted knowing that Costco examines every recipe and product to ensure you’re satisfied. 

The other reason is that you’re buying brand-name products, just without the cost. All of Kirkland Signature’s products are sourced from well-known brands within their industry, it’s just that Costco has created a special recipe or product within that brand name to use in their own private label. This means, that when you’re buying Kirkland Signature coffee grounds, you’re actually getting Starbucks coffee without paying extra for that label.

Is Kirkland Signature Available Anywhere Else? 

No. Kirkland Signature is exclusive to Costco. If you want to experience name brands at a discounted rate, you’ll need to head to your local Costco to shop for the brand.

Who Makes Costco Kirkland Products? 

So who exactly is behind Costco Kirkland Signature products? With the wide range of products that Kirkland Signature has, it’s safe to say that there are many. While we don’t know every product, we do know some. Here are just a few products that are sourced by big-name brands.

Alexander Murray Scotch

Kirkland Signature Scotch whiskies are incredibly affordable and tasty. These bottles are actually made by Scotch independent bottlers, Alexander Murray & Co., a brand that has become incredibly well-known in the industry over the past few years. Alexander Murray & Co. is based in Calabasas, California, and has been around since 2004. 

In a 2016 interview with Market Watch, the CEO and President of Alexander Murray, Steve Lipp, confirmed that Costco is one of the biggest sellers of their scotch, selling around 100,000 cases or more a year.

Diamond Pet Food

Don’t skimp on food for your furry friends! Kirkland Signature dog food is just as good as the rest of the premium brands you see at your local stores. There have been several reviews that confirm that Kirkland Signature get their dog food sourced from Diamond Pet Foods, which has a reputation for producing some of the highest quality pet food. 

They own several brands like Diamond Naturals, Nutra-Gold, and Taste of the Wild. Not only does your pet get the nutrients they deserve in all stages of life, but you don’t have to overspend to get the brand name.

That’s right! When you purchase the discounted price of Kirkland Signature coffee grounds, you’re actually getting high-quality Starbucks coffee. While Costco carries several big names for their coffee products, like Rogers Family and Kuerig Cups, Starbucks is one of the top ones. 

Starbucks is one of the top companies in the coffee industry. Starbucks began with its first store opening in 1971 in Seattle’s Pike Place Market and has since grown into one of the largest coffeehouse chains ever with 35,700 stores worldwide.

Jelly Belly Candy

Jelly Belly, Kirkland Signature, Costco

From scotch to jelly beans, Kirkland Signature has it all. But of course, Costco has their candy sourced from one of the leading names in confectionery. Jelly Belly is pretty much the king of beans in the candy world, so having Kirkland Signature’s private label on this 4lb jug is worthwhile. 

Jelly Belly was around in 1979 and has a total of 100 flavors. But for this tub of 49 flavors, it’ll only cost around $19.99. For a 5lb bag from Jelly Belly themselves at only 20 flavors, you’re looking at a rate of $69.99.

Bumble Bee Tuna

Kirkland Signature, Bumble Bee Seafood, Costco

Canned fish is a pantry staple for many. It’s quick to snack on and even better with recipes. But purchasing generic canned fish can be a gamble for many. Thankfully, Costco lets you enjoy canned fish without the worry about the quality. The Kirkland Signature canned tuna was confirmed to be sourced from Bumble Bee according to a 2003 interview with Money CNN

While Bumble Bee Seafoods didn’t truly get their feet on the ground until 1960, their history began in 1899 when seven canners began processing salmon. Bumble Bee Seafoods is in every major retailer and is known for creating canned, packaged, and even snack-processed fish.

In a 2016 interview with WSB-TV, CEO Craig Jelinek confirmed that Duracell is behind the batteries under Kirkland Signature’s name. Duracell was founded in 1924 and is one of the leading manufacturers of alkaline batteries, specialty cells, and rechargeables.
