Sugar-Free Energy Drinks: From Flavour Trends to Formulation
How beverage R&D teams can compare flavour concepts and assess caffeine bitterness and sweetener aftertaste.
What the market signals
In its Energy Drinks 2025 article, T. Hasegawa U.S.A. highlights citrus, ginger and yuzu among flavour directions to watch. Its earlier U.S. survey summary shows reported consumption of traditional sugar-free energy drinks rising from 17% in 2023 to 21% in 2024. These figures describe the U.S. survey. In Türkiye, Red Bull offers sugar-free editions and Hema İçecek lists sugar-free as an option for private-label production.
Two flavour directions for a pilot
Lemon–lime and yuzu–ginger are two starting points for a citrus pilot. Compare the flavour concepts in the same beverage base. Once a profile is selected, run a separate test to see whether a candidate taste modulator changes the sensory balance. T. Hasegawa’s technical material identifies caffeine as a possible contributor to unwanted taste and describes approaches to bitterness and high-intensity sweetener aftertaste.
How to set up the comparison
Prepare A, the control, and B, the same base with a candidate taste modulator confirmed for the application. Keep caffeine, sweetener, acidity, carbonation and serving temperature consistent. Use blind codes and alternate serving order. Record bitterness on the first sip, then the character and duration of the aftertaste. Check that the intended citrus or fruit character is still identifiable. Confirm the selected solution and dosage in the intended formulation before moving to pilot scale.
