Grocery List

• Produce: 1 fresh lime
• Dairy: None
• Pantry: Dark rum, spicy ginger beer, and ice cubes

Full Ingredients

For the Cocktail

• 1 1/2 cups firm ice cubes, plus more as needed to fill the glass
• 1/2 fluid ounce fresh lime juice, equal to 1 tablespoon
• 4 fluid ounces spicy ginger beer, chilled to 38°F (3°C)
• 2 fluid ounces dark rum

For the Garnish

• 1 lime wheel, about 1/4 inch thick, or 1 small lime wedge

Step-by-Step Instructions

Step 1: Chill the glass

Fill a 10- to 12-ounce highball or Collins glass with approximately 1 1/2 cups of ice. Stir the ice around the glass for 20 seconds to chill the sides thoroughly. If water collects at the bottom, carefully pour it out while keeping the ice in the glass. Add another ice cube or two if needed so the glass is filled nearly to the rim.

Step 2: Add the fresh lime juice

Measure 1/2 fluid ounce, or 1 tablespoon, of freshly squeezed lime juice and pour it evenly over the ice. Fresh juice is important here because its clean acidity cuts through the dark rum and sweet ginger beer more effectively than bottled juice.

Step 3: Pour in the ginger beer

Slowly add 4 fluid ounces of spicy ginger beer chilled to 38°F (3°C). Pour it down the inside wall of the glass to limit foaming and preserve as much carbonation as possible. Leave about 1 inch of space at the top of the glass for the rum.

Step 4: Gently combine the base

Insert a long bar spoon into the glass and make one slow, gentle rotation to distribute the lime juice through the ginger beer. Avoid vigorous stirring, which will flatten the bubbles and make the finished cocktail less refreshing.

Step 5: Float the dark rum

Hold the back of a bar spoon just above the ginger beer with the spoon tip touching the inside edge of the glass. Slowly pour 2 fluid ounces of dark rum over the spoon for about 10 to 15 seconds. The rum should spread across the surface, forming a dark amber layer above the pale, sparkling ginger beer.

Step 6: Garnish and serve

Place a 1/4-inch-thick lime wheel on the rim or tuck a small lime wedge beside the ice. Serve the cocktail immediately while the layers are distinct and the ginger beer is still lively. Present it with a straw or swizzle stick and stir before drinking so the rich rum, spicy ginger, and tart lime become evenly balanced.

Pro Tips

• Choose a bold ginger beer: Use a spicy, full-flavored ginger beer rather than a mild ginger ale. The extra ginger heat stands up to the richness of the rum.
• Keep everything cold: Chill the ginger beer to 38°F (3°C) before building the drink. Colder ingredients reduce ice melt and help preserve the layered appearance.
• Use dense ice: Large, firm cubes melt more slowly than small or hollow cubes, keeping the cocktail flavorful instead of watery.
• Pour the rum slowly: A slow pour over the back of a spoon creates the most visible separation between the golden ginger beer and dark rum.
• Use fresh lime: Squeeze the juice just before mixing for the brightest aroma and cleanest citrus flavor.

Variations

• Extra-Spicy Dark ‘n’ Stormy: Add 1/4 teaspoon finely grated fresh ginger to the lime juice before pouring in the ginger beer. Strain the lime mixture first if you prefer a smoother drink.
• Less-Sweet Version: Replace 1 fluid ounce of the ginger beer with 1 fluid ounce of chilled plain sparkling water. The drink will be drier while retaining its ginger flavor and fizz.
• Zero-Proof Version: Replace the dark rum with 2 fluid ounces of a zero-proof dark cane spirit. Build and garnish the drink in the same way.

Storage & Make-Ahead

This cocktail is best assembled immediately before serving and should not be stored after mixing because the ginger beer will lose carbonation and the ice will dilute the drink. Up to 24 hours ahead, squeeze the lime juice and refrigerate it in a tightly sealed container at 40°F (4°C) or colder. Chill the unopened ginger beer and dark rum in advance, and cut the garnish up to 4 hours ahead. Keep cut lime covered and refrigerated until serving. For several cocktails, pre-measure individual portions of rum and lime juice, but do not combine them with ginger beer until each drink is ready to serve.
