Hey, folks – I hope you’re all doing well!

Today, I’m thrilled to share another rhubarb cocktail that quickly became one of my favourites. Rhubarb and cherries are a classic culinary pairing, yet surprisingly few cocktails combine the two. The tartness of homemade rhubarb syrup perfectly complements the richness of cherry liqueur, while fresh lemon keeps everything crisp and lively. The result is a cocktail that feels familiar yet distinctive, making it equally suitable for a casual summer evening or a dinner party. So, let’s dive into this cherry rhubarb sour!

Why You’ll Love This Cherry Rhubarb Gin Sour with Empress 1908 Gin

If you enjoy classic gin sours but also appreciate seasonal ingredients, this Cherry Rhubarb Gin Sour deserves a place on your summer cocktail list. Although the ingredient list is short, each component contributes something unique to the final drink.

• Balanced sweet and tart flavours. Fresh lemon and rhubarb syrup create a lively backbone, while cherry liqueur adds just enough sweetness and depth.
• Elegant yet approachable. Despite its sophisticated flavour profile, this cocktail requires no complicated techniques or specialty equipment beyond a cocktail shaker.
• Perfect for homemade rhubarb syrup. If you’ve already prepared a batch of rhubarb syrup, this recipe is one of the most rewarding ways to enjoy it.
• Easy to customize. Depending on your preferences, you can make it more cherry-forward, slightly tarter, or even create a silky egg white version.
• Naturally beautiful. Homemade rhubarb syrup gives the cocktail its lovely rosy colour. Although I used Empress 1908 Indigo Gin, the syrup contributes most of the vibrant hue.

Cherry Rhubarb Gin Sour: Flavour Profile

Before making this Cherry Rhubarb Gin Sour, it helps to know what to expect. Unlike many fruit cocktails that lean heavily toward sweetness, this drink remains refreshing and spirit-forward.

• Bright citrus notes from freshly squeezed lemon juice immediately awaken the palate.
• Fresh rhubarb flavour provides pleasant tartness without becoming overpowering.
• Cherry liqueur adds subtle richness and a deeper fruit character rather than dominating the drink.
• Gin botanicals remain clearly noticeable throughout, especially when using a floral gin such as Empress 1908.
• Smooth, refreshing finish makes this cocktail remarkably easy to sip despite its complexity.

Overall, I would describe this cocktail as layered rather than bold. Every ingredient remains recognizable, yet they blend together beautifully instead of competing for attention.

What Is a Sour Cocktail?

Although countless modern variations exist, the sour is one of the oldest and most influential cocktail families. In fact, many popular drinks – including the Whiskey Sour, Pisco Sour, Amaretto Sour, and classic Gin Sour – follow exactly the same basic concept.

At its core, a sour contains just three essential components:

• A base spirit, such as gin, whiskey, rum, tequila, or brandy.
• Fresh citrus juice, most commonly lemon or lime.
• A sweetener, typically simple syrup, although fruit syrups and liqueurs are also widely used.

Many modern recipes also include:

• Egg white for a creamy texture and stable foam.
• Bitters to add aromatic complexity.
• Fruit liqueurs for additional flavour and depth.

This Cherry Rhubarb Gin Sour stays true to the classic sour formula. However, homemade rhubarb syrup and cherry liqueur give it a distinctive seasonal twist while preserving the bright, refreshing character that defines the family.

The Golden Ratio of a Classic Sour

Many bartenders begin with a simple guideline rather than a rigid formula. It provides an excellent starting point, but it should never prevent you from adjusting a cocktail to suit your ingredients.

A classic sour often follows something close to:

• 2 oz spirit
• ¾ oz citrus juice
• ½–¾ oz sweetener

Nevertheless, no homemade syrup tastes exactly the same. Some batches are intensely tart, while others are considerably sweeter. Likewise, different cherry liqueurs vary in both sweetness and fruit intensity.

For this reason, I always encourage tasting and adjusting.

For example, my homemade rhubarb syrup was especially tart. As a result, I used more cherry liqueur than the original ratio suggested, added a few drops of maraschino cherry syrup, and reduced the lemon slightly. The cocktail became more cherry-forward, yet gin and lemon still remained the predominant flavours.

Think of the classic ratio as a guide rather than a rule – the best cocktail is the one that tastes balanced to you.

Do Cherry and Rhubarb Pair Well with Gin?

Absolutely. While rhubarb and strawberries often receive most of the attention, cherries are equally delicious alongside rhubarb, especially in cocktails.

Several characteristics make this combination work particularly well:

• Rhubarb contributes bright acidity that keeps the drink lively and refreshing.
• Cherry liqueur adds depth with subtle sweetness and darker fruit notes.
• Gin botanicals bridge both flavours, especially citrus, floral, and herbal notes.
• Fresh lemon ties everything together, preventing the cocktail from becoming heavy.

I particularly enjoyed this recipe with Empress 1908 Gin. Its floral character complements both fruits beautifully. However, because the rhubarb syrup contributes most of the cocktail’s colour, using Empress is entirely optional. A quality London Dry or contemporary gin will produce an equally balanced Cherry Rhubarb Gin Sour.

Ingredients You’ll Need for This Cherry Rhubarb Gin Sour

Like most classic cocktails, this Cherry Rhubarb Gin Sour relies on just a handful of ingredients. Because each one plays an important role, using good-quality components will noticeably improve the final drink.

• Gin. Gin forms the backbone of the cocktail, adding botanical, citrus, and herbal notes. I used Empress 1908 Indigo Gin, whose delicate floral character complements both rhubarb and cherries beautifully. However, a quality London Dry or contemporary gin works equally well.
• Fresh lemon juice. Always use freshly squeezed lemon juice whenever possible. It provides brightness and acidity while balancing the sweetness of the syrup and liqueur.
• Rhubarb syrup. Homemade rhubarb syrup contributes tartness, sweetness, and much of the cocktail’s attractive pink colour. Since every homemade batch differs slightly, don’t hesitate to adjust the proportions to suit your syrup.
• Cherry liqueur. Cherry liqueur rounds out the drink with deeper fruit notes and subtle sweetness, creating a more layered flavour profile.
• Bitters. Although optional, I highly recommend using one dash each of cherry and orange bitters. Together, they add aromatic complexity without overpowering the cocktail.

Possible Additions and Variations

One advantage of a classic sour is how easily it adapts to different tastes. Once you’ve tried the original version, consider experimenting with one of these ideas.

• Make it creamier. Add egg white for a silky texture and a beautiful foam.
• Increase the cherry flavour. Add a little more cherry liqueur or a few drops of maraschino cherry syrup.
• Highlight the rhubarb. Increase the rhubarb syrup slightly while reducing the lemon juice.
• Try different bitters. Orange and cherry bitters are my favourite combination, but aromatic bitters also work well.
• Create a sparkling version. Shake the cocktail as usual, strain into a highball glass over ice, and top with club soda.
• Experiment with gin. Compare the floral character of Empress 1908 Gin with a classic London Dry to discover your favourite version.

Choosing the Best Cherry Liqueur for this sour

Cherry liqueurs vary considerably in sweetness and flavour, so don’t worry if you don’t have the exact bottle called for in a recipe. Simply adjust the balance as needed.

• Maraschino liqueur. Often considered the classic bartender’s choice, maraschino is relatively dry with subtle nutty and floral notes. It produces a lighter, crisper cocktail and usually requires little or no additional sweetness.
• Sweet cherry liqueur. This is what I used. It creates a fruitier, richer Cherry Rhubarb Gin Sour with more pronounced cherry flavour.
• Cherry brandy. Rich and smooth, cherry brandy works well if you prefer a fuller-bodied cocktail.
• Kirsch. Since kirsch is dry and less sweet, it produces a noticeably sharper drink. If using it, you may wish to add a little extra rhubarb syrup.

My version differs slightly from the classic approach because I didn’t have maraschino liqueur. Instead, I used a sweet cherry liqueur. Since my homemade rhubarb syrup was also quite tart, I increased the amount of cherry liqueur and added a few drops of maraschino cherry syrup. The result was more cherry-forward, while gin and lemon still remained the dominant flavours.

Choosing the Best Gin for This Cherry Rhubarb Sour

One of the best things about this Cherry Rhubarb Gin Sour is its versatility. Almost any quality gin can produce an excellent cocktail.

• London Dry gin delivers a crisp, juniper-forward profile that keeps the cocktail classic.
• Contemporary gin offers softer botanical notes and allows the fruit flavours to shine.
• Floral gin, including Empress 1908 Indigo Gin, beautifully complements both rhubarb and cherries without overwhelming them.

Although I made this cocktail with Empress 1908 Gin, it isn’t essential. Unlike many Empress cocktails, the rhubarb syrup contributes most of the drink’s gorgeous pink colour.

How to Make a Cherry Rhubarb Gin Sour

Fill a cocktail shaker with ice, then add the gin, fresh lemon juice, rhubarb syrup, cherry liqueur, and bitters. Shake vigorously for about 15 seconds until well chilled, then double strain into a chilled coupe glass. Garnish with a cocktail cherry or a lemon twist and serve immediately.

How to Make It with Egg White

For a silky, foamy version, add one fresh egg white (or about ¾ oz pasteurized egg white) along with the other ingredients. Shake first without ice for about 15 seconds (a dry shake) to build the foam, then add ice and shake again until thoroughly chilled. Double strain into a chilled coupe and, if desired, finish with a few drops of bitters on the foam for an elegant presentation.

Serving and Garnishing Ideas

Although this Cherry Rhubarb Gin Sour looks elegant on its own, a thoughtful garnish makes it feel even more special.

• Serve in a chilled coupe for the classic presentation.
• Serve over one large ice cube in a rocks glass if you prefer a slower-sipping cocktail.
• Garnish with a cocktail cherry to emphasize the cherry notes.
• Add a lemon twist for extra citrus aroma.
• Use a thin ribbon of fresh rhubarb when it’s in season for a beautiful seasonal garnish.
• Decorate the egg white foam with a few drops of bitters if making the frothy version.
