This is a super easy cocktail to just eyeball and make to taste. If you want, just squeeze a half of a lime into the cocktail instead of measuring. The traditional copper moscow mule mug is optional, but it just doen't feel like the same without one. The refreshing chill coming through the copper mug.Ginger Beer Note: Ginger Beer is not the same as gingerale (gingerale will work in a pinch). Ginger beer is usually less sweet and has more of a ginger "bite". Every brand will vary, so find the one that you like. Goslings Ginger Beer & Barritt's Ginger Beer are common choices & a good starting point.
1/2oz. (15ml)fresh Lime Juice*see head note
4oz.(120ml)Ginger Beer(not the same as gingerale)
Lime Wedge, for garnish
Add ice to a copper mug*see headnote. Pour in the vodka and lime juice (or just squeeze in 1/2 a lime - add the spent lime shell into the mug after squeezing).
Slowly pour in the ginger beer and gently stir. Garnish with a lime wedge if desired. Enjoy.
