Mello Yello is a caffeinated, citrus-flavored soft drink produced and distributed by The Coca-Cola Company which was introduced on March 1, 1979 to compete with Pepsi's Mountain Dew.
Mello Yello was withdrawn from Australia in the early 1990's, being replaced with the similar but uncaffeinated Lift.
There have been three flavored variants of Mello Yello in North America. Mello Yello Cherry was released in response to Mountain Dew Code Red. The other two variants were Mello Yello Afterglow (peach-flavored) and Mello Yello Melon. All three were only available for a limited time.
In early 2010, Coca-Cola announced new images of new packaging that it would be re-branding Mello Yello to resemble the packaging in 1979. This re-branding has included an expanded distribution of the product, into such areas of the United States that have not had the product in years such as the Northeast United States and the Western United States. In 2011, Mello Yello began to replace Vault on Coca-Cola Freestyle machines.
