Ranking All Dunkin’ Zero Energy Drinks: A Complete Guide

Dunkin’ offers a diverse range of beverages, catering to various tastes. From hot coffee drinks to milkshake-like blended options and teas, there’s something for everyone. In March 2026, Dunkin’ unveiled its new energy drink line known as Zero, aiming to join the competitive landscape of upcoming sports and energy beverages. Unlike traditional energy drinks, these offerings contain just 20 calories and zero sugar. Each flavor also boasts 145 milligrams of caffeine, providing an alternative caffeine source beyond coffee. Currently, Dunkin’ features six enticing flavors, prompting me to sample each one.

In my ranking of these drinks, I focused on the harmony of flavors, the authenticity of advertised tastes, and whether I’d consider having them again. Should you be contemplating a Zero energy drink, or unsure which flavor to try first, this guide might help you with your decision. Join me as I embark on this caffeine-fueled journey—perhaps next time, I’ll pair it with one of Dunkin’s breakfast sandwiches to balance out the caffeine rush.

Each Zero energy drink features unique flavorings combined with sparkling water and ice for a refreshing effervescence, reminiscent of Italian soda. Blushpop incorporates Blackberry Tangerine and Tropical Mango flavors, presenting a fruity blend. While the drink is undeniably fruity, it’s excessively sweet, making it difficult to pinpoint specific flavors. The taste can become overwhelming, leading to an unpleasant aftertaste that necessitates water to cleanse the palate. The tangerine and mango notes are faint, overshadowed by the dominating blackberry flavor. Overall, the sweetness detracts from the experience, landing this drink at the bottom of my rankings.

Tropical Mango fares slightly better than Blushpop, with a somewhat less cloying sweetness. While it’s more enjoyable to sip, it remains one of the sweeter options. The mango flavor is more distinguishable here compared to Blushpop, allowing it to emerge more clearly. However, the overall experience feels one-dimensional, akin to drinking a syrupy mango soda. While it’s enjoyable in limited quantities, the sweetness clings to the palate, and after a few sips, you may find yourself reaching for water to cleanse your mouth. For those who appreciate tropical flavors, this may still appeal to you on a hot day.

The Blackberry Tangerine flavor evokes the essence of sweetened fruit tea, albeit in sparkling form. The blackberry notes dominate, reminiscent of Dunkin’ Hibiscus Kiss tea, though it isn’t an exact match. This flavor prominently highlights the blackberry, with a hint of tangerine emerging towards the end of each sip. Compared to the previous drinks, Blackberry Tangerine strikes a better balance between flavors. It offers a more refined taste experience, with the berry and subtle citrus elements combining well. While it edges out Tropical Mango in flavor complexity, it’s not my top choice.

Juicy Peach is on the sweeter side but shows promise. I tried it as is, but customizing it could enhance the experience. Since there’s no option to adjust the number of flavor pumps, asking for a larger cup with extra sparkling water might help balance the sweetness. When overly sweet, it can resemble a flawed fountain soda. However, it improved as the ice melted, tempering the syrupy flavor. It reminds me of the San Pellegrino Peach & Clementine Zero Sugar Sparkling Drink, ranked third out of 12 San Pellegrino sparkling drinks. I enjoy it but find the next option more satisfying.

Glamberry combines flavors from both Blackberry Tangerine and Juicy Peach, delivering a more intriguing fruit medley. The berry and peach notes stand out prominently, while the citrus aspect is less perceptible. The delightful combination encourages repeated sips. Throughout the tasting, I noted that none of the Zero drinks exhibit the off-putting taste typical of many energy beverages, making them easier to enjoy. For those hesitant about energy drinks, Glamberry, along with the top contender, offers a pleasant option.

Topping my list is Sunzest, a standout drink that masterfully combines Tropical Mango and Juicy Peach for a vibrant flavor experience. The peach flavor hits first and seamlessly intertwines with the Tropical Mango, resulting in a delightful fusion that feels like a burst of spring and summer. This drink has garnered appreciation from many, and I often find myself standing alone in my evaluations, so it’s satisfying to find this similarity in taste. Sunzest serves as a refreshing alternative to coffee or tea and could be perfectly paired with items from Dunkin’s food menu, perhaps their hash browns.

The caffeine content is surprisingly undetectable, and the zero-sugar aspect is subtly blended, presenting a taste akin to a sparkling soda. The blend of familiar peach flavors complemented by a hint of mango makes this drink my favorite among the Six Zero options. If I were to choose just one to purchase again, it would inevitably be Sunzest.

The primary criteria for ranking included the balance of flavors, the extent to which the drinks reflected their advertised ingredients, and the likelihood of future enjoyment. Beverages that exhibited overwhelming sweetness or fell short of their flavor promises were ranked lower. In contrast, drinks that demonstrated a balanced and dynamic flavor profile received higher rankings. All items were ordered in medium size with no customizations to experience them as intended by the brand. After sampling each of these beverages, I felt a delightful caffeine buzz—followed by a pressing need for a nap.
