There are a lot more beverages at Costco than you might think. Of course, it has an array of sodas and popular name brand sips, but the Kirkland Signature options deserve a bit of love. They're hidden in various areas of the warehouse, from the fridge to the aisles, but they come with a lot of customer praise. 

I totally understand that buying a couple of gallons or countless containers of a particular beverage can seem daunting, especially if you haven't tried it before. That's why I am drawing on personal experience, Tasting Table articles, other rankings, and customer reviews to give you insights into why these drinks are fan favorites. These are loved for their flavor, flexibility in how you use them, and overall convenience. Then you can make purchases based on what makes sense for your household or needs, whether you're buying for a party or just something for your family to enjoy. 

No matter which drink you get, they are all terrific options you should try at least once. I have sweet and fruity options, something a bit tangy, and even a bubbly beverage so that you can find something for any occasion. For this list, we omitted alcoholic beverages, though there are many amazing Kirkland liquors and Kirkland Signature wine options. As a tip: All of these beverages come with at least two containers, so be aware of the best-by date, open and use one, and save the second for when you need it. Let's start sipping.

Kirkland's Organic Lemonade comes in two enormous 96-fluid-ounce containers. The sipper is made with filtered water, organic lemon juice concentrate, organic sugar, and organic lemon flavor, creating a thoroughly sweet-tart combination. The lemonade gets everything right by finding a tasty balance of sweet and mouth-puckering. It tastes refreshing and very lemon-forward so you never forget what you are drinking. Serve it straight from the jug into your favorite glass. It's perfect served over ice so it's even more frigid as you take a sip. The drink may be classic, but Kirkland still manages to make it shine. 

Once you open it, you need to refrigerate it; consider cracking it open if you know you'll be sipping it over the next few days or plan to serve it at a larger function. No matter what, that shouldn't be a problem, as Costco customers say they drink this regularly, if not daily. "My wife jokes and says that it must be flowing in my veins I drink so much of it," said one reviewer. Others share that it's the perfect sipper for a barbecue or even for taking to the beach. It's versatile too, whether you want to add some berries or perhaps use it as a drink mixer.

I like coconut water in general, and there are a couple of Kirkland Signature offerings to pick from. The most common is the shelf-stable one you'll find in the aisles next to the other packaged drinks. Organic Coconut Water was the top pick in a Kirkland beverage roundup. The writer thought it was scrumptious thanks to its clean but mild taste. It has the coconut flavor with hints of sweetness that come naturally from the coconut water. 

This is great because it comes in packs of 12 or nine, though the sizing is a bit different. The 12-pack has smaller bottles, which is ideal if you want to finish it in one go. These are delicious to sip straight from the container, but they work nicely in smoothies, too. One Costco reviewer said it's just about as close as you can get to cracking a coconut yourself. This is well worth purchasing for your household at least to test them out. But wait, there's another slightly hidden option: I am especially fond of Organic Coconut Water, a variety which you can find in the refrigerated section near the kombuchas and other cold drinks. This option is a little bit more expensive, and you only get six bottles, but the coconut water is really smooth and has a beautiful pink color.

Milk is a household staple, so you're probably well aware of Costco's selection. However, you don't have to buy the big old cartons. Next time you're shopping at the warehouse, consider grabbing the organic milk in the 18-count pack; it might be well worth it. You will get 18 small 8-ounce cartons of organic USDA organic whole milk. These are perfect to have on hand for school, picnics, or anything you may need, because they do not need to be refrigerated until opened. 

That makes them a handy shelf-stable option to keep in your pantry or garage until you need them. Of course, you can place them in the fridge to serve them cold, but, conveniently, it's not a requirement. After perusing the Costco reviews, this type of product is really handy for the elderly, who might not finish a whole carton before it spoils. People say they buy it for their families, parents, and retirement communities because it's so versatile and doesn't require refrigeration. This is a particularly great choice if you need something convenient or don't find yourself drinking large enough quantities of milk to justify purchasing the bigger containers. Reviews mention that they taste good and are amazing for everything from camping to kids' lunchboxes.

Apple juice is such a run-of-the-mill product you can get at virtually any grocery store. Therefore, you might not think that Kirkland's could be anything of interest, but I must admit, it is really scrumptious. It has a delightfully ripe, apple-forward flavor that tastes like you pressed the fruits yourself — something other people agree with. I find that it is quite sweet, so you could add a smidge of water to your cup without ruining the flavor. 

I think it is easily one of Kirkland's best juice options, but others sing praises about this item too. "Probably the best apple juice I've had in a very long time," said one Redditor. "Don't be like me and walk past it for two years, it is worth getting and trying." It's true. It's easy to trek past the jugs of juice in the drink aisle when you're already scrambling around for something more essential, like your favorite protein or bakery bread. Though it might not be at the top of your list, it is worth purchasing. You'll get 2 gallons of 100% U.S.-grown apples — and yes, it is 100% juice. It doesn't hurt that there are plenty of ways to make the store-bought juice taste even better, such as pouring some into a mug to steep your favorite tea or combining it with coconut water.

I love sparkling water; it gives me such satisfaction. If you feel the same way and find yourself reaching for sparkling water over things like juices and sodas, then you genuinely must get Kirkland Signature's Sparkling Water Variety Pack. This pack comes with 35 cans of sparkling water, where you'll get lime, lemon, and grapefruit options. The thing to note is that you get 15 cans of lime flavor, while the other two flavors get 10 each. 

Costco members love this stuff and say that they get two cases at a time. Others declare that it's better than name brands like La Croix or Spindrift. These are perfect, nice and crisp straight from the fridge, but you can pour soda into a glass, add a fruit garnish, or even mix it with your favorite juice. The grapefruit and lemon were first and second, respectively, in a Kirkland sparkling water taste test – the lime still made it into the top four. That is to say, it is loved by many and certainly should make it onto your shopping list at least once. They are true to flavor and refreshing, although our writer thought the lime was a little light on flavor. 

Costco really turned some heads when it introduced its energy drink variety pack in early 2026. Though they are one of the newest Kirkland beverages, the energy drinks have already become a fan favorite. The reviews on Costco's website are glowing, with people saying that every aspect is spectacular, from taste and value to energy levels. People say they have switched from name-brand to Kirkland. 

You will get a 24-count of orange, tropical, and peach flavors. They have zero sugar and 200 milligrams of caffeine to give you a jolt that you need. People say they are better than Celsius and ZOA. Customers have described the flavors as crisp, refreshing, pleasant, and all sorts of favorable adjectives. The consensus is that the flavors aren't too sweet and don't have a particularly potent flavor or carbonation, which can be a huge selling point for some. If you're looking for an affordable source of caffeine or an alternative to some of the pricier name-brand canned energy drinks, this is worth adding to your cart. In fact, they are one of the must-buy Costco items for 2026.

If you are on the hunt for a milk alternative, you already know that Costco has your back. The Kirkland Signature Almond Milk comes with a dozen 1-quart cartons, for a total of 3 gallons. The great thing about these is that they are unsweetened, which gives you more flexibility in how you like to use them. Pour in a dash of maple syrup or honey, and you're good to go; add a sprinkle of cinnamon into your milk or maybe use it as the liquid for your chia pudding; there are a bounty of ways you could use it. 

Reviews say the flavor and quality are great, and the packaging is convenient. Others note that they appreciate that it comes unflavored — sans sweetener or vanilla — which makes it easier to use in cooking. "Exactly What I Want in a Milk Substitute," one person on the Costco website said. The cartons are shelf-stable, so you can pop them in your pantry or tuck them away somewhere safe until you're ready to use them. There's also an organic vanilla-flavored almond milk that people adore. So you really can't go wrong with either Kirkland pick. The vanilla one comes with 6 quarts, so you get half the amount — just something that might factor into your grocery planning.

I am a long-time Costco shopper and have tried a range of things, whether that was for my own family, myself, work, or when hosting parties. These are some of my top picks, as well as options backed by fellow Tasting Table writers in their own reviews; I also sought out customer reviews so you could hear from more than one person about why these are top-notch signature beverages. 

Whether you want something bubbly, refreshing, and light, or prefer a versatile nut milk for your household needs, there are great Kirkland Signature beverages to pick from. Though there are other Kirkland beverages available in-store and online, these were selected for their fantastic flavors, versatility, and convenience. I hope these can bring some flavor and intrigue into your kitchen or whatever you're buying them for.
