Mountain Dew Ice (stylized as "MTN DEW ICE") is described by the brand as "a crisp, clear, carbonated soft drink made with a splash of real juice that will keep Dew Nation charged and refreshed."
Unlike Sprite, 7 Up, and Pepsi's own Mist Twist (stylized as "Mist Twst" but not "Mst Twst" for whatever reason), Mountain Dew Ice contains caffeine (91mg per 20 ounces).
The new soda arrives in stores nationwide starting Monday, January 15, 2018. You can find it in 20-oz bottles, 2-liter bottles, and 12-oz cans.
