Mountain Dew is a citrus-flavored, caffeinated, carbonated soft drink known for its bright green color and bold, refreshing taste that provides an energizing lift. Originally created in 1940 as a whiskey mixer, it is now owned by PepsiCo and is a popular beverage, especially among gaming and extreme sports enthusiasts. Its distinctive flavor comes from a combination of citrusy components, including orange juice, and it is often associated with a vibrant, adventurous lifestyle.
