Some say it evolved from medicinal drinks in the Middle East, while others trace it back to early American agriculture. Regardless of its origin, the Julep was a popular drink in the South by the 18th century, often enjoyed as a morning beverage: the alcohol helped ease aches and pains (in a time before aspirin), the sugar provided energy, and the mint awakened and refreshed the senses. It wasn't until the early 20th century that it became linked with the Kentucky Derby, maybe because those who worked in horse racing appreciated this combination of “therapeutic” properties. Or perhaps the Julep's "southern" connection to horse racing was, in part, a matter of proximity to the birthplace of bourbon, combined with a need for a little morning pick-me-up.

The Julep also holds a special place in cocktail history as one of the first popular drinks served with ice. With the rise of ice houses, ice was for the first time a readily available "garnish." Imagine the luxury of a frosty drink in the days before refrigeration!
