How many carbs are in keto mojito mocktail?

Each serving has 2.5g net carbs (3.5g total carbs minus 1g fiber), 12 calories, 0.3g protein, and 0.1g fat. This recipe makes 1 mocktail, with the carbs coming almost entirely from the fresh lime juice and mint.

Is this mojito mocktail alcohol-free?

Yes, this is a completely alcohol-free mocktail that uses sparkling water in place of rum. To make a boozy keto version, add 1.5 ounces of white rum, which is carb-free but adds about 100 calories per shot.

Why is fresh lime juice keto if fruit is high in carbs?

Lime juice is used in tiny amounts. One tablespoon contains only about 1.3g of carbs, so it adds bright citrus flavor without pushing you out of ketosis, especially when paired with a zero-carb sweetener like erythritol or monk fruit.

This bright, bubbly keto mojito mocktail delivers all the muddled mint and fresh lime flavor of the classic cocktail without the sugar, rum, or carbs. It comes together in five minutes and keeps you cool and refreshed at just 2.5g net carbs per glass.

Instructions

Add the mint leaves, lime juice, and powdered sweetener to a sturdy highball glass. Gently muddle for 15 to 20 seconds to bruise the mint and release its oils without shredding the leaves.

Add the lime wedges and give them a light press with the muddler to express a little more juice into the glass.

Fill the glass to the top with ice cubes.

Top with chilled sparkling water and stir gently from the bottom to lift the mint and distribute the lime.

Garnish with a fresh mint sprig and a lime wheel, then serve immediately while bubbly.

Tips & notes

Use a powdered (confectioners-style) sweetener so it dissolves cleanly; granular erythritol can settle and feel gritty at the bottom of the glass.

For a sweeter, more authentic mojito flavor, make a quick keto simple syrup ahead of time by simmering 1/4 cup water with 1/4 cup allulose until dissolved, then chill and use 1 tablespoon in place of the powdered sweetener.

Best made fresh and served right away, as the carbonation fades and the mint darkens within an hour.
