Mountain Dew "DEW.S.A" is a new flavor releasing around the 4th of July in the U.S. only. Technically this is a new flavor, but it combines three existing flavors together; Code Red, White Out, and Voltage. The release date will probably be before July 4th. The nutritional facts have not been leaked online so we don't know how much calories and caffeine it will have, and if it will contain artificial sweeteners or not.

​

UPDATE 3/5/17: DEW.S.A. will contain artificial sweeteners even though the three combined sodas currently do not contain them. They will most likely be Ace K (Acesulfame potassium) and Sucralose.

UPDATE 4/26/17: DEW.S.A. has been released, and it is now on the Dew Locator!
