Mountain Dew

Mountain Dew, stylized as Mtn Dew in some countries, is a carbonated soft drink brand produced and owned by PepsiCo. The original formula was invented in 1940 as a mixer by Tennessee beverage bottlers Barney and Ally Hartman. A revised formula was created by Bill Bridgforth in 1958. The rights to this formula were obtained by the Tip Corporation of Marion, Virginia. William H. "Bill" Jones of the Tip Corporation further refined the formula, launching that version of Mountain Dew in 1961.

"Mountain Dew" was originally Southern and/or Scots-Irish slang for moonshine (i.e., homemade whiskey or poitín), as referenced in the Irish folk song "The Rare Old Mountain Dew", dating from 1882. PepsiCo (then The Pepsi-Cola Company) acquired the Mountain Dew brand in 1964, and shortly thereafter in 1969 the logo was modified as the company sought to shift its focus to a "younger, outdoorsy" generation. 

In 2022, PepsiCo partnered with the Boston Beer Company to produce a line of alcohol-infused drinks in four flavors. Labelled "Hard Mtn Dew", the drinks were initially sold in Florida, Iowa and Tennessee, before expanding to other states.
