"On the rocks" can be traced back to ancient Scotland, the homeland of whisky's ancestors and inventors. In those times, prior to the existence of ice cubes and freezers, the story goes that ingenious Scots cooled their whisky using cold river stones. Today, many people enjoy whisky and other alcoholic beverages with one or two ice cubes. The use of these "rocks" allows you to enjoy alcoholic drinks and any other type of beverage at a refreshing temperature without diluting their content due to the ice melting effect.
