The Gin Gin mule was invented by Audrey Saunders, owner of Pegu Club—one of the early influential bars in the cocktail renaissance of the early/mid-aughts. And while the Gin Gin version of the Mule didn’t quite take on the ubiquity of the Moscow Mule among the cocktail-consuming public (it’s tough to argue with those copper mugs and an endorsement from Oprah), it gained credibility within the bartending community almost immediately. Soon after its creation, the drink popped up at other bars that were early entrants in the reinvigorated cocktail movement, like The Varnish in Los Angeles.
Today, the good word of the Gin Gin Mule has spread far and wide, and it’s one of a handful of newer cocktails that can justifiably be called classics. While it has elements of both a Mojito and a Buck, Saunders says her highball is a Mule through and through, thanks to the ginger beer. She uses a house-made ginger beer at Pegu Club that's super easy to make at home, but if you have to go with a store-bought version, we like a gingerier brand like Maine Root, Fever Tree or Reed’s. As long as you stay away from a sweet bottle of ginger ale, you’ll be OK.
