Moscow Mule Recipe in ml: A Bright, Balanced Cocktail

A Moscow mule is a fizzy cocktail made with vodka, fresh lime juice, and spicy ginger beer, traditionally served over ice in a copper mug. It is widely associated with 1940s America, though accounts of its exact origin differ. This adult drink is for people of legal drinking age; enjoy it responsibly, using the measurements below for a crisp, balanced single serving.

Ingredients

2 fl oz (60 ml) vodka
½ fl oz (15 ml) freshly squeezed lime juice
4 fl oz (120 ml) chilled ginger beer, or enough to top up the glass
1 cup (about 140 g) ice cubes
1 lime wedge, cut from about ⅛ of a lime, for garnish

Instructions

Chill the glass if you like. A copper mug is traditional, but a highball glass or other sturdy glass works just as well. For an especially cold drink, fill the glass with ice while you squeeze the lime, then pour out any water that collects.
Add the ice and base. Fill the glass with the measured ice. Pour in 2 fl oz (60 ml) vodka and ½ fl oz (15 ml) fresh lime juice. If you squeezed the lime directly over the glass, check for seeds and remove any that fell in.
Top with ginger beer. Pour in 4 fl oz (120 ml) chilled ginger beer. Give the drink one gentle turn with a bar spoon, just enough to combine the lime and vodka without flattening the bubbles. Taste before adding more ginger beer; the right amount depends on the glass and the drinker’s preference.
Garnish and serve. Add the lime wedge to the rim or drop it into the drink. Serve right away, while the ginger beer is lively and the ice has not diluted the cocktail.

Tips

Choose ginger beer, not ginger ale, for the classic flavor. Ginger beer is a nonalcoholic, carbonated mixer with a more pronounced ginger bite, though brands vary in sweetness and heat. Ginger ale is usually milder and sweeter, so it makes a softer, less peppery drink. If that is what you have, use it and reduce the lime slightly only if the result tastes too sharp.
Measure the lime rather than relying on the fruit. Limes differ in size and juiciness, and a large squeeze can overwhelm the vodka and ginger. The 15 ml (½ fl oz) amount gives a clear citrus note without making the drink sour. If your lime is especially tart, begin with about 10 ml (2 teaspoons), taste, and add the remaining juice a little at a time.
Keep the mixer cold and pour gently. Chilled ginger beer needs less ice to cool the drink, which helps limit dilution. Add it after the vodka and lime, then stir only briefly. Vigorous stirring or pouring from too high can release carbonation before the drink reaches the table.
Use the copper mug as a serving choice, not a requirement. A mug makes the drink feel especially cold in the hand, but it does not change the basic recipe. Use a clean mug intended for serving beverages, or choose glass if you do not have one. The copper color is traditional; the important elements in the glass are cold ice and fresh fizz.

Serving Suggestions

Serve the mule immediately after mixing, with a napkin or coaster under the glass if condensation is likely. A lime wedge gives guests the option of adding another squeeze, while a thin wheel or half-moon slice makes a tidy garnish. If you are serving several people, set out chilled ginger beer and fresh lime wedges, but add the ginger beer to each glass at the last moment so it stays carbonated.

The standard proportions make one drink with a noticeable ginger kick and a clean lime finish. For a longer, lighter-tasting serve, add a small splash of cold sparkling water after the ginger beer. That softens the ginger flavor and adds volume, so offer it as an optional adjustment rather than changing the core recipe. Keep water and nonalcoholic drinks available alongside cocktails, and label any drink that contains alcohol when serving a group.

Variations

Make it less sweet or more ginger-forward. Ginger beer brands range from dry and fiery to sweet and mild. Start with the measured 120 ml, taste, and adjust with another small pour if the flavor is too intense. A drier ginger beer makes the lime stand out; a sweeter one rounds off the citrus. Avoid adding extra lime automatically, since that can make a sweet mixer taste unbalanced rather than less sweet.

Use bourbon for a Kentucky mule. Replace the vodka with 2 fl oz (60 ml) bourbon and keep the lime and ginger beer quantities the same. Bourbon brings oak and caramel notes, so the cocktail tastes warmer and richer. Rye whiskey also works if you prefer a drier, spicier finish. Both are variations rather than the vodka-based standard.

Try a dark-and-spicy version. Swap in 2 fl oz (60 ml) dark rum for vodka. Its deeper molasses-like flavor pairs well with ginger beer and lime, though it changes the drink substantially. Taste before adding any sweetener; many ginger beers are already sweet enough. Garnish with lime as usual.

Make a nonalcoholic mule. Leave out the vodka and use ½ fl oz (15 ml) lime juice with 4 to 5 fl oz (120 to 150 ml) ginger beer over ice. Top with a splash of sparkling water if you want a less sweet drink. For more body, use a nonalcoholic spirit made for mixing, following its label because products differ in strength and flavor. This version is a useful option for guests who do not want alcohol.

Add a restrained herbal note. Gently clap one small mint sprig between your palms and use it as a garnish, or add a thin slice of cucumber. These additions bring a fresh aroma without taking over the ginger and lime. Avoid muddling mint aggressively: crushing it hard can make the drink taste grassy, and the classic mule does not require herbs.

Storage and Reheating

A finished Moscow mule is best consumed as soon as it is made. Once it sits over ice, melting water dilutes the drink and the ginger beer gradually loses its fizz; refrigeration cannot restore either texture. There is no reheating step for a cocktail, and warming it would spoil its intended cold, carbonated character.

If you need to prepare ahead, measure the vodka and fresh lime juice into a covered container and refrigerate them for up to 24 hours. Keep the ginger beer sealed and chilled separately, then combine the components with fresh ice just before serving. Refrigerate any perishable prepared mixture within 2 hours; discard a drink that has been left out longer rather than saving it. Freshly squeezed lime juice is most aromatic on the day it is made, so squeezing it shortly before serving gives the brightest result.

Frequently Asked Questions

What is the usual Moscow mule ratio?
The recipe here uses 2 parts vodka, ½ part lime juice, and 4 parts ginger beer by volume. That is a useful starting point, not a strict rule: ginger beer sweetness and strength vary, and ice and glass size do too. Keep the vodka and lime measured, then adjust the ginger beer slightly to taste.

Can I make a Moscow mule without a copper mug?
Yes. A highball glass, rocks glass, or any sturdy glass that holds ice works. The mug is a familiar traditional serving vessel, but it is not an ingredient and does not make the drink. Chill the glass if convenient, and focus on using cold ginger beer and serving promptly.

Is ginger beer alcoholic?
Most ginger beer sold as a soft drink is nonalcoholic, but alcoholic fermented versions are also available. Check the product label rather than assuming. For this recipe, use a nonalcoholic ginger beer as the mixer; the vodka supplies the alcohol.

Can I mix a batch for a party?
Yes, but keep the carbonated mixer out until serving. For each drink, combine 60 ml vodka with 15 ml lime juice, then scale those amounts to the number of servings and refrigerate the mixture in a covered container. Pour individual portions over ice and add 120 ml chilled ginger beer per glass. This keeps the fizz stronger than mixing a full pitcher in advance.

How can I make the drink less strong?
Use less vodka and replace the missing volume with extra ginger beer or sparkling water. For example, 45 ml vodka with 120 ml ginger beer and 15 ml lime makes a milder-tasting glass while preserving the familiar flavors. It still contains alcohol, so serve it as an alcoholic drink and adjust the amount responsibly.

Can bottled lime juice replace fresh lime?
It can work when fresh limes are unavailable, but bottled juice often tastes less bright and may have a sharper or more processed flavor. Start with 10 ml (2 teaspoons), taste, and add more only if needed. Freshly squeezed juice is the better choice for a simple cocktail where lime is one of just three main flavors.
