🍹 Keto Caipirinha Recipe — Brazil’s Iconic Cocktail, Made Low-Carb

The Caipirinha (pronounced kai-pee-REEN-ya) is Brazil’s national cocktail — simple, refreshing, and packed with citrusy punch. Traditionally, it’s made with lime, sugar, and cachaça, but that sugar adds unnecessary carbs. Luckily, with a smart swap, you can enjoy this tropical favorite while keeping it keto-friendly.

In this recipe, we’ll break down each ingredient, why it belongs in the drink, and how to adapt it for a low-carb lifestyle.


🥃 Ingredients (Per Glass)

  • 1 lime, cut into wedges (about 5–6g net carbs)

  • 2 teaspoons Keystone Pantry Allulose (0g net carbs)

  • 2 oz cachaça (Brazilian sugarcane spirit) (0g carbs)

  • Ice cubes or crushed ice


🧾 Ingredient Breakdown & Keto Benefits

Lime 🍋

The star of the Caipirinha. Limes bring acidity, freshness, and bright tropical flavor. They also contain vitamin C and antioxidants. While limes do contribute a small amount of carbs (about 5–6g net carbs per fruit), they’re essential to the balance of this cocktail. The tartness cuts through the spirit’s warmth and gives the drink its signature zing.

Keto Note: One lime won’t derail your carb count for the day, especially if you enjoy this drink occasionally.


Keystone Pantry Allulose 🍬

Traditionally, Caipirinhas use white sugar, but that adds around 8g carbs per drink. Allulose is a natural rare sugar that tastes and behaves like sugar but has zero net carbs and no impact on blood sugar levels. It dissolves beautifully when muddled with lime and gives the same smooth sweetness without the carb load.

Keto Note: Allulose makes this cocktail fully keto-approved, transforming a 14g-carb drink into a much lighter option.


Cachaça 🥃

Cachaça is Brazil’s beloved sugarcane spirit — similar to rum but with a fresher, earthier, and slightly grassy flavor profile. Despite being made from sugarcane juice, it’s distilled, meaning all the sugars are converted into alcohol, leaving 0g carbs behind.

Keto Note: Like vodka, rum, or tequila, cachaça is naturally carb-free, making it an excellent choice for a keto-friendly cocktail.


Ice ❄️

It may seem simple, but ice is a key ingredient in a Caipirinha. Crushed ice chills the drink quickly, dilutes slightly to mellow the alcohol, and creates that refreshing, beachside experience Caipirinhas are famous for.

Keto Note: No carbs here — just the essential chill factor.


🍸 How to Make a Keto Caipirinha

  1. Place lime wedges into a sturdy glass.

  2. Sprinkle with 2 teaspoons of Keystone Pantry Allulose.

  3. Muddle gently to release the lime juice and oils from the zest.

  4. Fill the glass with ice (crushed if possible).

  5. Pour in 2 oz cachaça.

  6. Stir well to blend flavors.

  7. Garnish with a lime wheel and enjoy!

❓ Keto Caipirinha FAQ

Q: Is cachaça keto-friendly?
A: Yes! Although it’s made from sugarcane juice, cachaça is a distilled spirit. All the sugars are fermented into alcohol, leaving behind 0g carbs per serving — making it keto-friendly, just like vodka, rum, tequila, or whiskey.


Q: Can I use rum instead of cachaça?
A: You can substitute light rum if you don’t have cachaça, but the flavor will be slightly different. Rum tends to be sweeter and smoother, while cachaça has a fresh, earthy, grassy note that makes the Caipirinha unique. For the most authentic experience, stick with cachaça.


Q: Why use allulose instead of sugar?
A: Traditional Caipirinhas use sugar, which adds about 8g carbs per drink. Allulose provides the same sweetness and mouthfeel but with zero net carbs and no blood sugar impact. It keeps the drink keto-friendly while preserving authenticity.


Q: How many carbs are in a traditional Caipirinha?
A: A classic Caipirinha made with sugar has about 13–14g carbs per drink (mostly from sugar, with some from lime). Our keto version cuts that down to just 5–6g net carbs, coming only from the lime.


Q: Can I make this cocktail even lower in carbs?
A: Yes! If you want to cut carbs further, you can reduce the amount of lime used or swap some wedges for a squeeze of lime juice. This will slightly reduce the citrus oils but lower the carb count closer to 3–4g net carbs.


Q: Is all alcohol keto-friendly?
A: Not all alcohol is keto. Beer, sweet wines, liqueurs, and cocktails made with syrups or mixers usually contain high amounts of sugar. Distilled spirits like vodka, rum, tequila, whiskey, gin, and cachaça are carb-free and safe in moderation on keto.
