The Gin Moscow Mule is a spinoff from the classic Moscow Mule recipe created by Jack Morgan and his two other friends. The classic Moscow Mule is made with lime juice, vodka and ginger beer. But unlike the classic that is best served in copper mugs, the Gin Moscow Mule is usually served in tall glasses. The preference of the glass, though, really depends on the bartender's take to the cocktail.Gin Moscow Mule is also known as Gin-Gin Mule. The name was coined from the gin and ginger beer which are the trademark ingredients for this cocktail. It is a very popular cocktail and was named as one of the 25 most influential cocktails of the century in the May-June 2010 issue of the Imbibe Magazine, a Portland, Oregon based magazine that features all kinds of beverages. This magazine is published every two months and has already received a number of awards for its authoritative articles on all beverages, especially the up and coming ones.
