– Fruity, refreshing, and moderately tart grapefruit as the flavor base
– There is a gentle, effervescent note in the aftertaste that does not intrude on the aroma
– Overall, a pleasant interplay of flavor notes, ranging from fruity and tart to a slightly tart-sweet finish
– The flavor is somewhat reminiscent of Collagen Peptides Pink Grapefruit, combined with a slight sports drink-like touch
– Especially when served ice-cold, it's a delicious refreshment with an extra boost of electrolytes and caffeine

8.5 / 10 Suppligator Rating – What's the community saying?

– First taste impression of a classic sports drink with a fizzy, artificially sweet, somewhat indefinable, fruity flavor
– After a short time, an orange note emerges, which becomes more noticeable as the experience progresses
– The finish leaves a slightly sweet-and-sour fruity note, combined with a distinct “isotonic touch”
– Overall, the balance between the fruit and other flavor notes is a bit off, but it's still very refreshing and easy to drink—with the added electrolytes and caffeine
– The flavor is reminiscent of a mix of Ahoj-Brause Orange, the yellow Nimm2 candies, and Vitaminbrause
