Publisher's Synopsis
Cocktail an iced drink of wine or distilled liquor mixed with flavoring ingredients." While that's a pretty broad definition, it reflects the modern practice of referring to almost any mixed drink as a cocktail.
The first published definition of a cocktail appeared in an editorial response in The Balance and Columbian Repository of 1806. It read: "Cocktail is a stimulating liquor, composed of spirits of any kind, sugar, water, and bitters." That's the accepted definition of ingredients used today when referring to the "ideal" cocktail.
