New York (CNN) — 7UP, which popularized lemon-lime flavoring when it rolled out nearly a century ago, is changing its taste for the first time in 15 years. The soda is permanently reformulating its recipe as it faces increased competition, slightly reducing lemon for a “lime-forward” taste in response to younger drinkers’ thirst for citrus flavors. 7UP’s refreshed recipe will also be used in Cherry 7UP, as well as zero sugar versions that debut in mid-August. The lemon-lime beverage category generates $5 billion in revenue in the United States, according to Circana. Still, the lemon-lime category is dominated by Coca-Cola’s Sprite, controlling a 9% share of 2025 sales.
