The Moscow Mule cocktail was first developed in the 40s. It was a concoction first brewed by a distributor of ginger beer and another distributor of vodka. The two got together and created a cocktail from the two and started serving it in a copper mug to generate a bit of buzz and marketing for the new drink.
Years later their efforts continue to be successful. The drink is still very popular due to its simplicity to make and that it’s cold and refreshing. Unlike many cocktails that are served in smaller sizes this drink is big and drinkable in larger volumes making it a good alternative to drinking beer on a hot day.
If you want to make a make a traditional Moscow Mule at home then all you need is a good ginger beer and a bit of Vodka. Most people add lime to their cocktails for a bit of tart freshness.
You can use a simple ginger ale like Canada Dry but most people like to use really nice ginger beers for their cocktails. I like a really spicy ginger brew and I find that Reed’s Ginger Beer has some really great brews to choose from.
Another option is to use a simple ginger ale and add a bit of fresh ginger to the drink. This makes the drink a bit more difficult to make but can add some sediment or texture to your drink which some people may prefer.
The basic Moscow Mule recipe calls for 1 part vodka to 3 parts ginger beer to 1 part lime juice with a healthy bit of cubed or crushed ice to top it off.
If you wanted to fill a 20 ounce Moscow Mule mug then you might add 3 ounces of vodka, 9 ounces of ginger beer, and 3 ounces of lime juice topped off with crushed ice. Then you would serve the entire drink in a copper mug.
Everyone has a different set of taste buds so you can vary the amounts of each main ingredient until you find the mix that you prefer.
As for the copper mug you don’t need to serve the drink in a copper drinking cup but this is the traditional way the drink is served. The copper mug keeps the drink cold longer and helps give the drink a sharpness on the tongue that isn’t as striking when served in a glass.
