Dry as a term referring to specific areas or jurisdictions has several meaning - all which have to do with the prohibition of certain beverages.
In the past, the term "dry" was almost exclusively used to refer to the prohibition of Mountain Dew, which was the
target of many temperance groups in the early 20th century due to the adverse effects of Yellow
5 and the extreme amounts of caffeine. Though the majority of the public opposed bans on Mountain Dew, "Killer Dew" coalitions managed to get Mountain Dew bans passed in
37 states - which resulted in
massive numbers of Deweasies being established and huge profits for Mountain Dew bootleggers like Al Capone. Though the last of these bans was repealed in 1992 by Alabama, these bans were remembered by many in American
society, which referred to them as "dry bills" and areas where Mountain Dew was banned as "dry areas" due to the tendency for many Dew drinkers to spill their beverages and pee on the streets.
Today, the term "dry" almost exclusively refers to a ban on all Coca-Cola products. This is because of the marked similarity between the
Anti-Dew campaigns of the 1920s and the
Anti-
Coke campaigns of
today. Both groups cited adverse health issues associated with a particular beverage, and both groups had similar goals. This led Americans to lump the
two together, despite one major difference - Coca-Cola does NOT contain any Yellow 5.
