Mountain Dew (currently stylized as Mtn Dew in the United States and Canada) is the main drink in the Mountain Dew line, and is commonly referred to as the "original" flavor.
Original Mountain Dew is a flavored soda that redefines citrus.
- Main article: Mountain Dew Timeline
Mountain Dew's first lemon-citrus formula was developed back in 1940 by Barney and Ally Hartman, whom were beverage bottlers in Tennessee. It was first distributed in 1954. In 1958, Bill Bridgforth created an improved formula for the drink by merging the existing formula with his Lemonade soda.
It was in 1964 when PepsiCo acquired the brand and production rights of Mountain Dew, allowing them to bottle and distribute it across the country.
Mountain Dew has lasted through each generation since, and has evolved with each, as seen in its series of packaging/logo changes over the years. The drink has since spawned an entire line of products, each with its own flavor or theme; and has launched numerous campaigns and promotions to reach out to its increasingly huge fanbase.
In 2012, Mountain Dew Canada changed the name of this flavor to "Citrus Charge", making Canada the first country to have a different name for the original flavor of Mountain Dew.
Mountain Dew had also been sold in India under the name "Mountain Dew Neon" and sold alongside the regular flavor. Despite the name, Mountain Dew Neon was the same flavor as regular Mountain Dew and the only differences lie in packaging and marketing.
As of April 2018, Arby's had switched to Coca-Cola products which means that Arby's no longer served Mountain Dew in their soda fountains.
As of June 18th, 2018, Frisch's Big Boy, a Cincinnati restaurant company, switched to Coca-Cola products which means that Frisch's Big Boy no longer served Mountain Dew and the Diet version in their soda fountains. Coca-Cola products were expected to be in Frisch's soda fountains by September 2018.
