Red Bull Summer Edition (Sudachi Lime)

Red Bull’s annual Summer Edition has returned for 2026 with Citrus Zest, a seasonal flavor based on the bright and tangy profile of Sudachi lime. The limited-time extension first surfaced in the United Kingdom, where it launched in both regular and sugar-free versions, giving you the choice of the calorie level. It also rolled out in multiple can sizes, including the larger 16oz or 473ml, packing a scaled 151mg of caffeine, on par with most of the Monster Energy family.
