This Rhubarb Gin Sour Cocktail adds a flavor twist to the classic craft cocktail. Made with gin, lemon juice, egg white, and homemade rhubarb syrup, this cocktail is sure to become a new favorite.
The Gin Sour cocktail is a classic for a reason. It's the perfect balance of sweet and sour with a creamy element from the egg white (which is optional). I added a spin on this classic by adding some fresh rhubarb syrup in place of the usual simple syrup or sugar. It creates a unique and delicious flavor combination that is perfect with gin.
How to Make A Rhubarb Gin Sour Cocktail
- Place all of the ingredients into a cocktail shaker and dry shake (no ice).
- Add fresh ice to the shaker and shake again until everything is nice and cold.
- Strain through a fine-mesh strainer into your favorite cocktail glass.
- Garnish with a fresh sprig of mint or a rhubarb ribbon (see recipe card for notes).
What Gin to Use
The traditional Gin Sour Cocktail calls for a London dry gin. Because this drink has a fresh garden element from the rhubarb syrup, I would suggest using a botanical dry gin like Aviation Gin or Aria Gin. There are so many different varieties of gin out there and you can certainly use whatever gin you prefer. Any gin will be delicious in this drink.
Egg White Alternative for Cocktails
An alternative to adding egg white to cocktails is to substitute aquafaba. Aquafaba is the “bean liquid” usually from garbanzo beans/chickpeas. It’s gluten-free and dairy-free and an excellent alternative for people with an egg allergy, who don’t consume eggs, or do not want to use raw egg white. Simply substitute 1-2 tablespoon of aquafaba for 1 egg white.
You don’t have to add egg white to this cocktail. I personally like the foam it creates and it makes this cocktail so pretty. Not everyone is comfortable adding egg white to their drink, and that’s ok! See my notes in the recipe card on the USDA comments on egg whites in the recipe.
Tools Needed to Make a Gin Sour
When making a cocktail with egg white or aquafaba, you will need a fine-mesh strainer to achieve that beautiful foam on top.
Any cocktail that is shaken will require a cocktail shaker.
It's also very important to properly measure your ingredients when making a cocktail. If you eyeball it, you will not be happy with your results. Try this set for all of your measuring needs.
And a beautiful cocktail deserves the right glass. This cocktail looks great in a coupe glass like these basics below.

- *The US Department of Agriculture (USDA) considers it safe to use raw eggs if they are pasteurized. Bottom Line: Raw eggs may contain a type of pathogenic bacteria called Salmonella, which can cause food poisoning. However, the risk of an egg being contaminated is quite low. Please proceed at your own risk and decide if you are ok with this. I have never had an issue.
- To make a rhubarb ribbon, use a vegetable peeler and peel off a thin strip of rhubarb bark.

What a delicious and refreshing drink! Perfect for summer!
My son just made rhubarb syrup and has been looking for cocktails to make with it so I'm passing this along.
Oh good, I hope he enjoys this one!
I love this cocktail! Cocktails are so frequently too sweet for me, but this was well balanced. And I love the tip about making the curl - garnishes are important!
Thanks, Jenn. I agree garnishes are so important. Cheers!
oh great idea to use aquafaba! love this
Aquafaba is such a good substitute for egg white and there is no difference in the taste 🙂.

I am always looking for more rhubarb recipes, and this one is so special, as is the rhubarb syrup itself! Such a fun cocktail! And, we still have rhubarb growing well in this hot August heat thanks to extra watering.
How nice, you can enjoy rhubarb all summer! Our rhubarb is usually best at the beginning of the summer so I make extra syrup for later. Enjoy!
This Gin Rhubarb Cocktail is just what the Dr. ordered. Perfect for a hot summer day!
Yes! It's perfect for hot summer days!
