What makes pepsi throwback and Mountain Dew different than regular pepsi?

Pepsi Throwback is made with real sugar instead of high fructose corn syrup, giving it a different taste profile that some consumers find more nostalgic or "classic." Mountain Dew, on the other hand, is a citrus-flavored soft drink with its own unique formula, featuring higher caffeine levels and a distinct flavor that sets it apart from both regular Pepsi and Pepsi Throwback. While both alternatives offer a different taste experience, the key difference lies in their ingredients and flavor profiles.
