Moscow Mule Recipe: A Bright Ginger-Lime Cocktail

A Moscow Mule is a refreshing American cocktail made with vodka, fresh lime juice, and spicy ginger beer, served cold over ice. Its lively balance of citrus and ginger makes it easy to mix directly in the glass, and the garnish and ginger-beer amount are simple to adjust to taste.

This drink is for adults of legal drinking age; drink responsibly.

Ingredients

1½ fl oz vodka (45 ml): Choose a neutral, unflavored vodka so the lime and ginger remain clear. A standard 80-proof vodka is suitable.
½ fl oz fresh lime juice (15 ml): This is 1 tablespoon (15 ml), usually about half of a juicy lime. Squeeze it just before mixing for the brightest flavor.
5 fl oz ginger beer (150 ml): Use a carbonated, nonalcoholic ginger beer, not ginger ale. Ginger beers vary in sweetness and heat, so choose one you enjoy drinking on its own.
1 cup ice cubes (about 140 g): Use enough to fill the serving mug or glass nearly to the top. Larger, firm cubes melt more slowly than crushed ice.
1 lime wheel or wedge (about 10 g): Cut from a washed lime for garnish. A wedge can also be squeezed into the drink at the table.
1 small mint sprig (about 2 g), optional: This adds a fresh aroma, but the cocktail is complete without it.
2 dashes aromatic bitters (about 1 ml), optional: Bitters add a faint spice note. Leave them out for a straightforward vodka, lime, and ginger version.

Instructions

Prepare the glass and garnish. Chill a copper mug or a sturdy highball glass if convenient, then cut a lime wheel or wedge. If using mint, rinse it and gently pat it dry. A copper mug is traditional, but a glass works just as well; choose a food-safe lined mug rather than unlined copper for contact with acidic lime.
Add the vodka and lime. Pour 1½ fl oz (45 ml) vodka and ½ fl oz (15 ml) fresh lime juice into the mug. Add the optional bitters now so they distribute easily. No cocktail shaker is needed: building the drink in its serving glass keeps the method quick and avoids losing carbonation later.
Fill with ice. Add about 1 cup (140 g) ice, or enough cubes to fill the mug almost to the rim. The drink should be cold before the ginger beer goes in. If the glass is only partly filled, the smaller amount of ice may melt faster and dilute the cocktail.
Top with ginger beer. Slowly pour in 5 fl oz (150 ml) ginger beer. Pouring gently helps preserve its fizz. Give the drink one brief, gentle stir from the bottom upward with a bar spoon or long spoon; avoid vigorous stirring, which knocks out carbonation.
Garnish and serve right away. Add the lime wheel or wedge and, if desired, the mint sprig. To release mint aroma, lightly clap the sprig between your palms before placing it on top; do not muddle it, since crushed mint can add bitter, grassy flavors. Serve with a straw or a cocktail pick and enjoy while the ice is firm and the ginger beer is sparkling.

Tips

Choose ginger beer by its flavor, not just its label. Some bottles are sharp and peppery, while others are sweeter and mild. If yours tastes especially hot or sweet, start with about 4 fl oz (120 ml), taste, and add more as needed. Ginger ale is a possible fallback, but it is usually softer, sweeter, and less ginger-forward, so the finished drink will taste gentler and less spicy.

Use fresh lime and measure it. Bottled lime juice can work in a pinch, but its flavor is often flatter or more tart than freshly squeezed juice. Start with the stated ½ fl oz (15 ml); adding extra lime without adjusting the ginger beer can make the drink too sharp. If your lime is unusually tart, add a small splash more ginger beer rather than sugar, which can blur the crisp flavor.

Protect the bubbles. Add ginger beer after the vodka, lime, and ice, then stir only once or twice. Do not shake the ginger beer with the other ingredients: carbonated liquid can foam and lose its sparkle. Open the bottle immediately before pouring and keep the remaining ginger beer chilled according to its label.

Keep the ice and cup clean. Large, solid cubes make a colder drink with less rapid dilution than crushed or partly melted ice. If using a copper-style mug, make sure its interior is lined with food-safe stainless steel or another suitable coating. A chilled glass is an easy substitute, and there is no need to buy special bar equipment to make a good Mule.

Serving Suggestions

Serve the Mule as soon as it is mixed, while the ginger beer is fizzy and the ice is still holding its shape. A lime wedge gives guests the option to add more citrus, while a lime wheel makes a simple garnish that does not crowd the rim. If you use mint, keep it fresh and place it where its aroma can be noticed as you lift the glass.

For a casual gathering, set out chilled ginger beer, cut lime, ice, and measured vodka so each drink can be built individually. This is better than pouring a large batch over ice in advance, because ice melts and carbonation fades while a pitcher sits. Serve alongside salty snacks such as roasted nuts, crisp potato chips, or savory appetizers; their texture and saltiness pair well with the cocktail’s tart, gingery character.

Variations

Make it less sweet or more tart. Use a drier ginger beer, or begin with 4 fl oz (120 ml) and add a little at a time. For extra citrus, increase the lime juice by 1 teaspoon (5 ml), taste, and stop when it is balanced. Adding a large pour of lime all at once can overwhelm the ginger, so adjust in small increments.

Try a different spirit. A Kentucky Mule substitutes bourbon for vodka, bringing a warmer, oakier taste. A Mexican Mule uses tequila for a more vegetal, peppery flavor. Keep the same starting quantities—1½ fl oz (45 ml) spirit, ½ fl oz (15 ml) lime, and 5 fl oz (150 ml) ginger beer—then adjust the ginger beer to suit the spirit and your preference.

Add cucumber or berries. For a cucumber Mule, add two thin cucumber slices to the glass before the liquid and press them gently once with a spoon; do not crush them into pulp. For a berry variation, lightly press two raspberries in the glass before adding the vodka and lime. Both options make the drink fruitier and can add a little color, while the ginger beer still supplies the characteristic spice.

Make a no-alcohol version. Leave out the vodka and use 5 fl oz (150 ml) ginger beer with ½ fl oz (15 ml) lime juice over ice. For a little more body without adding alcohol, top with 1 fl oz (30 ml) chilled sparkling water or a nonalcoholic spirit designed for mixing. The result is a ginger-lime cooler rather than a traditional Mule, and the flavor will depend on the ginger beer you choose.

Storage and Reheating

A Moscow Mule is best mixed and served immediately. Ice quickly dilutes the drink, and ginger beer loses carbonation after it is poured, so an assembled cocktail does not store well. If you need to step away, refrigerate any leftover drink within 2 hours; expect it to be flatter and more diluted, and do not keep it for more than a day. Discard a drink that has been left at room temperature for longer than 2 hours.

For a small amount of advance preparation, squeeze the lime and measure the vodka into a covered container, then refrigerate for up to 24 hours for best flavor. Add fresh ice and ginger beer only when serving. Keep opened ginger beer refrigerated and follow its package directions for how long it retains quality. There is no reheating step for this cold cocktail.

Frequently Asked Questions

Can I make a Moscow Mule without a copper mug?
Yes. A highball glass or another sturdy drinking glass works perfectly. The mug is a familiar way to serve the drink, but it does not change the ingredients or method. If choosing copper, use a food-safe lined interior because acidic drinks such as this one contain lime juice.

Is ginger beer alcoholic?
Most ginger beer sold for making this cocktail is a nonalcoholic carbonated soft drink, but products can differ. Check the label if you need to confirm its alcohol content. The recipe’s vodka is what makes this version an alcoholic cocktail.

Should I shake a Moscow Mule?
No. Mix the vodka and lime directly in the serving glass, add ice, and top with ginger beer. Shaking carbonated ginger beer can make it foam and lose bubbles. If you prefer to chill the vodka and lime first, you can shake those two ingredients with ice, strain them into a fresh glass of ice, and add the ginger beer afterward.

What can I use instead of ginger beer?
Ginger ale is the easiest substitute, but it usually tastes sweeter and less spicy, making a milder Mule. Start with a slightly smaller pour, taste, and add more if needed. A ginger syrup combined with plain sparkling water can also provide ginger flavor and fizz, but it is often sweeter and less crisp than ginger beer.

Can I make a pitcher ahead of time?
You can combine the vodka and lime juice in a covered pitcher and refrigerate it for up to 24 hours, but do not add ice or ginger beer until just before serving. Pour the chilled mixture into individual ice-filled glasses and top each one with ginger beer. This preserves the fizz and prevents the pitcher from becoming watery.
