Complete reviews and rankings of all six Kirkland Signature Sparkling Energy Drink variety pack flavors
Kirkland Signature Sparkling Energy Drink variety pack features six distinct flavors, each meticulously crafted for a unique taste experience. From bright citrus to bold berries, we've analyzed every flavor in depth. Discover which ones match your energy style, time of day, and taste preferences.
Crack open a can and you're immediately hit with a bright, energizing citrus aroma—a blend of orange, lemon, and a hint of grapefruit. The first sip is crisp and refreshing, with a snappy bite that wakes up your palate. The carbonation is strong and lively, creating a tingling sensation on your tongue.
A complex citrus medley that doesn't feel one-dimensional. You get authentic orange sweetness balanced with tart lemon and a subtle grapefruit earthiness. The finish is clean and dry without being harsh. Some drinkers notice a very slight sucralose aftertaste (the sweetener) on the back of the palate, but it's minimal and doesn't linger long.
Open the can and you're greeted with a rich, fruity aroma that smells like fresh raspberries and blackberries. The first sip is immediately satisfying—smooth, jammy berry flavors coat your palate without any sharpness. The carbonation is medium to strong, creating a pleasant effervescence that doesn't overpower.
A sophisticated berry blend dominated by raspberry and blackberry with subtle blueberry notes underneath. The drink feels naturally sweet (courtesy of the formula) without being cloying. The finish is smooth and slightly fruity—it lingers pleasantly without artificial flavor. Minimal sucralose aftertaste makes this one of the cleaner-tasting flavors in the lineup.
The aroma is unmistakably tropical—sweet mango and subtle passion fruit create an inviting, vacation-like scent. The first sip delivers creamy mango sweetness with a slightly tart passion fruit bite underneath. The carbonation is moderate, giving it a lighter mouthfeel than more aggressive flavors. Your taste buds immediately know: this is a tropical vacation in a can.
Juicy mango is the star, with passion fruit adding complexity and tartness. There's a creamy quality to the finish that suggests subtle vanilla or coconut notes working in the background. The aftertaste is clean and fruity, with a lingering mango sweetness. The sucralose sweetener is barely noticeable here, making it one of the more naturally-tasting flavors available.
Open a can and you're hit with a bright, fresh watermelon aroma that's refreshingly clean. The first sip is crisp and juicy, tasting like fresh-cut watermelon with a light sugar coating. There's a subtle saltiness (from electrolyte minerals) that actually enhances the watermelon flavor rather than detracting from it. The carbonation is strong and adds to the refreshing quality.
Pure, clean watermelon flavor that doesn't taste artificial or waxy. There are subtle hints of fresh lime or citrus in the background that add tartness and prevent the drink from being one-dimensional. The finish is refreshing and crisp, with the watermelon notes lingering pleasantly. Sucralose aftertaste is minimal, and the light sweetness feels balanced.
The aroma is immediately identifiable—sweet, slightly jammy grape scent that smells like premium grape juice. The first sip is bold and unapologetic: this is a dedicated grape flavor, not a subtle hint. The sweetness is pronounced, and the flavor is rich. Carbonation is moderate to strong, creating a pleasant fizzy sensation. This is for dedicated grape lovers.
Deep, fruity grape flavor reminiscent of dark concord grapes or premium grape juice. It's sweeter than some of the other flavors and leans into jammy, candy-like notes. The aftertaste is grape all the way—it lingers noticeably. Some sensitive to sucralose find this flavor amplifies the artificial sweetener aftertaste slightly more than others, likely because of the grape flavor's natural affinity with sugar.
The can opens with a bright, tart lime aroma mixed with subtle cherry notes—it smells like a premium cherry-lime soda. The first sip is immediately striking: tart lime hits first, then smooth cherry sweetness follows. The combination is sophisticated and well-balanced. Carbonation is strong and clean, creating a crisp, tangy sensation that enhances the flavor complexity.
This is a masterclass in flavor balance. Cherry provides natural sweetness and jammy richness, while lime adds tartness and prevents the drink from being cloying. The two flavors dance together rather than fight. The aftertaste starts tart (lime) and finishes sweet (cherry), creating an interesting transition. Minimal artificial aftertaste makes this one of the most naturally-tasting flavor combos in the lineup.
This is the breakout star of the lineup. The moment you open a Peach can, you’re hit with an authentic, delicious peach aroma. It smells like fresh peaches—not artificial, not overly perfumy. The anticipation is real, and the first sip absolutely delivers.
Pure juicy peach flavor with subtle floral notes and whispers of vanilla cream that create an almost creamy mouthfeel. This is the drink that converts skeptics. The balance between natural-tasting sweetness and refreshment is nearly perfect. It tastes like a premium energy drink experience without the premium price tag.
Open an Orange can and you get bright, zippy citrus that’s impossible to ignore. This is the energizer of the bunch—the flavor that wakes up your taste buds immediately. It smells like fresh oranges with a clean, crisp edge that promises an invigorating experience.
Crisp, bright, and genuinely refreshing orange flavor. There’s a complexity here that suggests mandarin notes layered beneath the primary orange, giving it a premium feel. Unlike many artificial orange drinks, this tastes like real citrus. It’s the perfect morning or pre-workout kick, especially for those who love citrus energy drinks.
All six flavors in the variety pack are excellent—each excels in different ways and appeals to different tastes. Here's how they rank overall, plus guidance on which to choose based on your preferences.
The most balanced and versatile flavor. Smooth raspberry-blackberry blend with minimal artificial aftertaste. Works beautifully any time of day, for any activity. This is the flavor that convinced us the variety pack is well-designed.
A sophisticated pairing that surprises and delights. Perfect balance of tart lime and sweet cherry. Equally compelling in the morning, pre-workout, or afternoon. The complexity keeps it interesting across multiple drinks.
Exceptionally refreshing with a clean, light character. Ideal for hot weather or post-workout. The subtle lime tartness prevents one-dimensionality. If you want hydration with energy, this delivers.
Smooth tropical flavor with genuine mango sweetness and passion fruit complexity. Works well for afternoon energy without being too intense. Great for those who find some flavors too aggressive.
A solid multi-citrus blend (orange, lemon, grapefruit) that delivers morning punch and pre-workout energy. Crisp and bright, though citrus energy drinks are common. Still excellent for those who love citrus.
Bold, unmistakable grape for dedicated grape lovers. Very sweet with pronounced jammy character. Not for subtle-flavor preference, but if you want bold, this delivers. Some find the sweetness and artificial aftertaste slightly more pronounced than others.
The variety pack includes 4 cans of each of the six flavors. With ratings ranging from 8.4 to 9.4 out of 10, you truly can't go wrong. Each flavor has its moment to shine and its ideal drinking occasion.
