The Moscow Mule is a classic highball made fancier by having its own special glass. So far I have always made them in collins glasses but I finally got some copper moscow mule mugs and made them up properly. The copper mug is able to hold temperatures better than glass, resulting in a colder cocktail for a longer time with less dilution. They are certainly delicious in any glass but these mugs are gonna be a game changer in the summer.
So before we get into the simple recipe, a mule and a buck are the same thing. They are both highballs involving ginger ale/ beer. The gin buck is what I am most familiar with although I have heard of gin gin mule as well and I dont know why the are different. Perhaps they are not and buck is classic terminology and it got renamed after the popularity of moscow mules? That popularity began in LA in the 50's as a bit of marketing for the new on the scene russian vodkas. You don't really need a recipe for this, you can do it to taste. Keep in mind, you don't want too much soda because there will be some dilution from the ice and the whole point of naming it a mule is that its got some kick to it. Here's how I usually do it, with some citrus adjustment based on brand of ginger beer. (Reeds is way more citrusy and requires less):::::::::::::
3oz ginger beer
1/2oz lime juice
Fill copper mug with ice. Add vodka and lime and stir. Top with ginger beer. Add more lime wedges to taste. Unless I've already squeezed a lot of lime juice, I usually just ream half a lime into the glass then throw in the entire half peel.
Tequila also makes a fine substitute at the same proportions....
