We, as Americans, like our products to do double duty. Even beyond reversible belts and zip-off pants, we want our foods and beverages to be multifunctional. We’re talking protein ice cream and adaptogenic chocolates and, the topic of this ranking, caffeinated water.
Yep, you can finally buy a beverage that both hydrates and stimulates. But what’s the best caffeinated sparkling water to buy? After two eye-opening taste tests, we have the answer.
What we looked for in the best caffeinated sparkling water:
- Flavor: Good sparkling water with caffeine should taste like good seltzer water. We didn’t want any bitter caffeine aftertaste—just a kiss of fruit or plain, crisp bubbly water.
- Fizz factor: Obviously the best sparkling water with caffeine should be pleasantly fizzy. We preferred small, spritzy bubbles.
- Caffeine content: We included a range of caffeine contents on this list. Ideally, we were looking for a can of caffeinated water that would give us enough of a caffeine jolt that it could stand in for a cup of coffee.
We gathered widely available brands and flavors to find the best caffeinated sparkling water you can buy. This list is extensive, tasty, and has enough caffeine to keep you up until the wee hours of the morning.

Best Caffeinated Water, Ranked
- Hiball Grapefruit Energy Seltzer (100mg caffeine)
-
There are lots of grapefruit seltzers out there and Hiball makes one of the best I’ve tried (and definitely the best caffeinated version). The taste is crisp, light, and citrusy. It’s also the most caffeinated of all the sparkling water with caffeine on this list. Grapefruit fans, grab this! — Jordan Myrick

- Ardor Cucumber Mint Sparkling Water (70mg caffeine)
-
If you’re a seltzer hater (me), this is the caffeinated sparkling water for you. It tastes like soda! Sprite, specifically. If you are looking for an actual seltzer, please steer clear of this—it’s zero sugar but it’s sweet. Speaking of clear, this is not. It’s the color of Mountain Dew. Once again, this is a caffeinated sparkling water for sparkling water haters (once again, me). — Jordan Myrick

- Heywell Energy + Lift Cherry Limeade (75mg caffeine)
-
This caffeinated water is water the same way that Spindrift is water, because it’s flavored with not just “natural flavors” but there’s also actual juice in the mix. In fact, one can is 6% juice. It’s nicely tart and zesty—it really does taste like cherry limeade. It goes light on the cherry so you don’t get any of that potentially medicinal flavor. And it includes not only 75mg of caffeine but also some stuff that purports to reduce stress, as well, such as ashwagandha, lemon balm, and l-theanine. If you’re looking for a caffeinated sparkling water that gives you more than a buzz, this is the one to buy. — Justine Sterling

- Ardor Mexican Lime Sparkling Water (100mg caffeine)
-
I was shocked by how much I liked this caffeinated sparkling water. It tastes so wonderfully limey. And not just like lime juice. You can taste lime zest and rind. It’s like they juiced the whole lime into a can of caffeinated sparkling water. — Jordan Myrick

- Juno Mineral Water Rocket (125mg caffeine)
-
All of the other brands of caffeinated seltzer on this list are flavored waters. But, just like not everyone likes milk and sugar in their coffee, some folks don’t want any flavor in their caffeinated water. And this is the best caffeinated water for those people. Made with Celtic salt and 125mg of caffeine, this unflavored caffeinated sparkling water is super fizzy with big, plentiful bubbles. And it truly doesn’t taste like anything except plain seltzer. There’s no bitter caffeine aftertaste. It’s just bubbly water that gets you going. — Justine Sterling

- Ardor White Peach Sparkling Water
-
Ardor White Peach was our favorite classic fruit flavor of caffeinated sparkling water. It has such a nice peachy taste without coming off as artificial. It hits the perfect balance between flavorful and subtle. In general, Ardor makes a good caffeinated water. You’re not going to go wrong with any of their flavors, but White Peach is certainly the best. — Jordan Myrick
