Jungle juice is the name given to an makeshift mix of liquor that is usually served for group consumption. There are countless recipes and even websites devoted solely to it. The term has also been used for similar less-than-reputable alcoholic concoctions.
Henceforth, it was born out of the necessity to keep soberness at bay by soldiers located in jungles abroad. Specifically US soldiers stationed in the Southwest Pacific during WWII. The United States did not provide its soldiers with “booze”. So, being Americans they channelled their industriousness and made their own hooch.
They fermented anything sugar-based they could get their hands. The results was often a swampy-looking 100-proof elixir of rum punch that was sure to get you good and smashed. They mixed their swamp water with whatever they could find, often lemonade. Thus the birth of American go-to party beverage was born – Jungle Juice. This is also the basis for typical student trashcan juice.
