Some cocktails have a bark much worse than their bite. The swamp water cocktail thankfully gets its name from its murky green appearance and not from suspect ingredients pulled from the bayou. This cocktail actually has a couple of variations -- one specifically for the sweet tooth and another for the more adventurous. The sweeter version is rum-based, while the more exotic one contains Chartreuse, a high-proof herbal French liqueur. Both recipes are simple enough -- you only have to decide how sugary you want your swamp water to be.
