Lately I’ve been going through old posts and rediscovering why I liked them so much. Case in point is the keto grapefruit gin fizz cocktail. It’s a refreshing cocktail and I love the flavor combination of ginger and grapefruit! It’s the perfect drink for warmer weather.

My hubby and I made these last weekend and he loved it. He’s not usually one for fruity cocktails but he liked the citrus flavor of the grapefruit with the gin. I don’t always like the taste of gin but with the grapefruit and ginger flavors it was delicious. And the carb count was only 2.9 grams.

There is a tasty simple syrup that goes with this drink and it makes quite a bit so you can keep it in the refrigerator for making non alcoholic drinks too. It has all the flavor without the alcohol and still tastes great.

What type of liquors can you use in this drink?

Most clear alcohols like vodka, gin, rum and tequila have 0 carbs. You have to watch with flavored alcohols as they may have added sugar but the standard liquors will not have any carbs. So they are good drink options if you have a low carb lifestyle. However watch out for the mixers which can have a lot of sugar in them.

I usually prefer vodka in my mixed drinks and you can definitely use that in this recipe. However I also really liked the gin in this one and it is a gin fizz after all. You could probably make it with rum and tequila too but for best results use the gin or vodka. 

Recipe ingredients I used and substitutions.

I just used a few simple ingredients to make this tasty drink – fresh grapefruit, gin, diet ginger ale and a low carb simple syrup. The simple syrup consisted of water, sweetener, fresh ginger root and grapefruit zest.

Fresh Grapefruit
Fresh grapefruit is essential to this recipe because I used a bit of the juice and the zest from the skin. The grapefruit zest is a great way to add flavor without carbs. If you don’t care about carbs you could use bottle pink grapefruit juice. Just make sure there are not any added sugars if you can.

Ocean Spray 100% juice and Simply Grapefruit are two fruit juice brands to try. We are only using 2 tablespoons of juice per drink the impact won’t be too bad crabwise.

Sweetener
My favorite low carb sweetener is Swerve. Today I used their Allulose blend but you can use your choice of sweetener or sugar substitute. And if you don’t care about carb counts you can just use white sugar.

Fresh Ginger & Diet Ginger Ale
If you can find fresh ginger root that would be great. You can also use the ginger paste if you can’t find the root. Aldi carries the paste and sometimes the fresh ginger root.

You use this in the simple syrup but if you can’t find any you could possible skip the simple syrup and just go with the diet ginger ale (any brand). You will want to add a bit of sweetener to the drink and the zest of the grapefruit if you can.

Gin or Vodka
As I mentioned above this delicious gin cocktail can also be made with vodka if you prefer. It might even taste alright with rum or tequila but it’s meant to be made with gin. Any brand will do. I try to buy middle shelf for my keto drinks.

How to make a keto grapefruit gin fizz.

Step 1: To make the simple syrup, heat up a small sauce pan. Turn the heat to medium heat. Add the water, sweetener, grapefruit zest and grated ginger root.

Step 2: Bring the mixture to a simmer and whisk until the sweetener has dissolved. Let it simmer on low for about 5 minutes to reduce the liquid and make it more concentrated. Take off the heat and let cool a bit. When cool, strain into a small jar and set aside.

Step 3: Fill a cocktail shaker with ice and then add the grapefruit juice, gin and a teaspoon of the simple syrup. Mix and pour into a cocktail glass. Then add enough ginger ale according to your tastes. You can make the drink stronger or weaker to suit you.

If you want you can add a simple garnish to this low carb cocktail by adding a grapefruit slice to the rim of the glass. I love the added pink color.

Cover and store the simple syrup in the refrigerator for a month or so. Please scroll down to view the printable recipe card.

As I mentioned above you can easily make this tasty drink into a mocktail for those who have an alcohol free lifestyle. Just eliminating the alcohol. I’m drinking one right now as a matter of fact!

Other variations and ways to make this drink.

• Use club soda or seltzer water instead of the diet ginger ale. Then add the grapefruit zest and some grated ginger to your glass. Of course you’d want to use the gin and grapefruit juice. And you will want to add some sugar substitute or sweetener.
• Substitute diet ginger beer for the ginger ale. Ginger beer is typically spicier and it gets its carbonation for fermentation. You’ll have to taste test a bit to get the right balance of ginger to grapefruit.
• You can play around with grapefruit and/or ginger flavored seltzer waters as low carb mixers for this cocktail. There are so many of these on the market these days.
