The limited-time holiday flavor is actually clear rather than brown in color (maybe so as not to be mistaken with cola?). It's described as "Dew with a blast of artificial gingerbread flavor" and comes in both 12-oz cans and 20-oz bottles.

You can find Mtn Dew Gingerbread Snap'd now at participating retailers nationwide and online, while supplies last.
