I first made this keto lemon drop martini recipe for the New Year’s Eve as I like to try new alcoholic drinks every year. However now this recipe has become a keto cocktail I drink all year round.
Originally I made it with some Meyer lemons because they gave it a little special flavor but they are not in season all year round so usually I make them with regular lemons.
This is the perfect cocktail for those on a keto diet. It’s refreshing and light so it’s a great sugar free drink for summer as well.
How many carbs are in a martini?
Martini’s are generally made with gin and vermouth. Gin like most alcohol or spirits have 0g carbs. However sweet vermouth has 4g net carbs in 1 oz whereas dry vermouth has 3.4g net carbs per 1 oz (source).
Since you usually only use 1/2 oz of vermouth then the standard dry martini would have only 1.7g net carbs.
Sometimes the term “martini” is used to refer to mixed drinks that mostly use hard alcohol like a cosmopolitan or today’s lemon drop martini recipe. There are so many different kinds of martinis. Learn more about them here.
What’s in a lemon drop martini?
There are only 4 simple ingredients in this low carb martini: vodka, fresh lemon juice & zest, Swerve sweetener and lemon flavored seltzer water.
Specific ingredients and substitutions.
I originally used Meyer lemons because they have a little different taste from regular lemons. However they might be hard to find as they are in season from December to March. I got mine at Trader Joes.
However you can use regular lemons if you want. Note that you want to use both the juice and the zest of these fruits.
As for the vodka I suggest a mid shelf brand. I used Absolute Citron because it has no carbs. However there are many brands of citrus flavored vodka. Just make sure they are not sweet and don’t have added sugar.
And the last two items are La Croix lemon seltzer water and Swerve confectioners sweetener. You can use any kind of lemon flavored sparkling water. And I like the confectioners because it dissolves easily.
If you only have granulated sweetener you might want to make a simple syrup first.
Making a quick simple syrup.
To do this, add 1 cup of water and 1/2 cup of granular sweetener to a pot. Heat until the sugar dissolves completely and then take it off the stove. When it cools down refrigerate it. In this recipe you would 2 tablespoons of the syrup.

A note about the nutrition: I had a hard time figuring out the nutrition for a Meyer lemon. I read that they are sweeter than regular lemons because they have less citric acid. I found this information that said 1 oz of Meyer lemon had only 0.5g net carbs. The other elements of this drink have no carbs. So for this recipe I just used the information for regular lemon juice. Please use your own calculation if you are worried about accuracy.
