The cocktail........a UK invention "The evolution of the cocktail Nobody is exactly sure when the first ?true? cocktail was created, but by the 1860s the drinks using this name usually included some form of liqueur. Bartenders were introduced to the concept officially in 1862, with the publication of How to Mix Drinks by ?Professor? Jerry Thomas, which included ten recipes for ?cocktails?, differentiated from the other drinks in the manual by the introduction of bitters. This charismatic American author and bartender helped to solidify the cocktail?s reputation as an overwhelmingly US-based invention, with a sophistication unmatched by early UK variants. However, the principles behind the cocktail originate far earlier, with some considering London punch-house proprietor James Ashley, who mastered his craft between 1731-1776, as the first to pioneer the mixology which led to the creation of the first ever cocktail."
