Non-alcoholic additives, juices mixers
Generic for plain water used as a diluting agent in various mixed drinks, sometimes as the sole mixer. Historically American whiskey is often requested with water using a euphemism such as Bourbon spring water," "Bourbon branch water," or simply "Bourbon branch". Branch is a term for an underground tributary of water. Water is a constituent in all potable alcohol, be it whiskey, vodka, brandy, rum, gin, or liqueurs. As an additive to classic mixed drinks it was used in the original forms of the cocktail, the sling, the fizz, the swizzle, the julep, punch, and many, many others.
