8 Best New Costco Beverages Of 2026 (So Far)

Costco is well-known for its constantly evolving lineup of products across its many warehouses, and 2026 has been no different. While we already discussed the best new deli items at Costco in 2026 a few months back and will likely look toward other departments as the year comes to an end, today is all about the many drinks and beverages that stole the show at Costco despite not having appeared at stores prior to this year.

While it isn't always the most noteworthy category at grocery stores, Costco has a large, varied, and popular selection of drinks; meaning each new product has big shoes to fill if it wants to live up to the hype. This year, Costco has expanded its assortment of pre-packaged teas and coffee drinks as well as capitalized on the popularity of both health-oriented beverages and energy drinks. However, not all of the new beverages are created equal — these ones stood out from the crowd and have impressed the overall Costco fanbase.

Starting things off is a beverage with a minor caveat. Saint James Organic Brewed Tea technically first arrived at select Costco locations back in 2024, but its nationwide rollout at the retailer didn't take place until July 2026. Since then, the organic tea brand has been a heavy-hitter on Costco shelves. The variety pack containing Saint James Red Raspberry and Classic Mango which is currently available at the store has been well-reviewed by Costco shoppers online.

Moving on from bottled tea to canned coffee, Slate Mocha Lattes were one of the first new beverages to appear at Costco this year, having been spotted by shoppers in mid-January. The drink is a flavorful blend of coffee and ultra-filtered milk; making it tasty, convenient, and appealing to people with lactose-free diets. Slate Mocha Lattes are set apart even further by their nutrition profile. Each can of the drink features 14 grams of protein and just 1 gram of sugar, making it a popular choice for anyone looking for a healthier ready-to-drink coffee option.

A more seasonal ready-to-drink coffee that debuted at Costco this year was La Colombe Pumpkin Spice Latte. While not everyone has been onboard with the pumpkin spice craze over the years, this La Colombe product was met with plenty of praise when it arrived in late summer, even making it onto our list of the best new Costco finds of August 2026. The drink is frothy and creamy despite being lactose-free and is easily among the best seasonal drinks you'll find at Costco.

Moving on to a new version of an already very popular product which just recently made its way to Costco, the Starbucks Strawberry Açaí Lemonade Refresher was an immediate hit at the wholesale store. Since June, the Starbucks product has been sold in 2-packs at Costco, with each individual container having 40 ounces of Refresher within it. Because the drink is intended to be mixed with water, this equals 20 servings of the drink altogether.

The product is not currently available on Costco's website but people have spotted the 2-pack of Starbucks Strawberry Açaí Lemonade Refresher for just $8.99 when shopping in-person.

Perhaps the most unique drink that has debuted at Costco in 2026 is from Clean Simple Eats, which released its Frosted Lemonade Protein Soda in May. In terms of both flavor and substance, the drink has been a hit. The beverage is currently only available in the Southwestern United States, but the company hopes to expand to nationwide distribution in the future. And it may very well succeed since the soda contains a whopping 20 grams of protein in each can while still tasting like a fairly typical frosted lemonade.

Because this drink is currently only a regional item, it's not yet available on Costco's website. Where available, a 12-pack of the canned beverage costs $31.99, making it one of the more expensive drinks on this list.

Next up is the only Kirkland Signature product on this list, but it most certainly deserves a spotlight. Costco's private label created an instantly beloved sparkling energy drink that has quickly become one of the store's must-try items in the form of the Kirkland Signature Sparkling Energy Drink. The beverage first rolled out in March and, while it was quickly called out as a Celsius dupe by many online, it has several qualities that energy drink fans are sure to enjoy. Each 12-ounce can contains 200 milligrams of caffeine, and every flavor — tropical, orange, and peach — has a clean, mild flavor that's still quite enjoyable despite containing zero sugar.

Mocktails are sometimes seen as mere stand-ins for alcoholic beverages, but the Recess Zero Proof Craft Mocktails that have been at Costco since May of this year are far from simple replacements. The drinks were featured on our list of the best summer beverages at Costco this year and are known for their bold flavor thanks to the agave included in the recipe. At Costco, the non-alcoholic beverages come in variety packs that feature three unique flavors — Classic Cosmo, Lime Margarita, and Grapefruit Paloma.

Finally, the first and only alcoholic beverage on this list is a popular, limited-time drink that took Costco by storm this past August. The Ziz Hugo Sparkling Spritz is a 750-milliliter bottle of carbonated wine that's known for its exquisite flavor and refreshing mouthfeel. In fact, the ready-to-drink Costco product does a great job of emulating the traditional, freshly-made cocktail it's named after, the Hugo Spritz. 

The drink's availability is questionable due to it being a limited release, but if you do manage to find one they're $9.99 for a bottle.
