Summer has always been my favourite season. Give me a sunny terrace, a barbecue with friends, or a warm evening that seems to last forever, and I’m in my element. While I’ll happily pour myself a dram of whisky even when the thermometer climbs well above 25°C—usually later in the evening, when the air starts to cool—most people instinctively reach for something a little lighter and more refreshing during the day. And when it really gets too hot outside? I like to opt for refreshing Summer Whisky Cocktails!
That doesn’t mean whisky has to stay on the shelf until autumn.
In fact, I think whisky makes some of the most characterful summer cocktails you’ll ever taste. Unlike vodka or white rum, it brings depth, texture and personality to every glass. Whether it’s the gentle smoke of an Islay single malt, the orchard fruit of a Speyside whisky or the sweet spice of a good bourbon, the right whisky doesn’t disappear in a cocktail—it becomes the reason you remember it.
I’ve always believed that the best whisky cocktails don’t try to hide the whisky. They celebrate it.
If you’re looking for the history of whisky cocktails, timeless classics like the Old Fashioned or Manhattan, or want to understand why whisky and cocktails have gone hand in hand for more than two centuries, be sure to check out my Complete Guide to Whisky Cocktails. There you’ll find the stories behind the classics and several essential recipes to get started.
Today, however, we’re doing something a little different.
These are the eight whisky cocktails I keep coming back to every summer. Some are famous, others are less well known, but every single one lets the whisky remain the star of the show.
New York Sour
My Favourite Version: Ledaig Sinclair Series with a Rioja Float
If I could only drink one whisky cocktail for the rest of the summer, this would probably be it.
The New York Sour already sits among my all-time favourite cocktails, but after experimenting one evening I discovered a combination that completely transformed it. Instead of using a bourbon, I reached for Ledaig Sinclair Series, a beautifully peated single malt finished in Rioja wine casks. Then, rather than using any red wine for the float, I matched it with a good Rioja.
It felt like the two were made for each other.
The gentle smoke weaves through the fresh lemon juice, while the Rioja finish in the whisky creates a seamless bridge to the wine floating on top. The result is smoky, fruity, refreshing and surprisingly elegant. It’s one of those drinks that always gets people asking, “What did you put in this?”
A Brief History
Despite its name, the New York Sour probably wasn’t born in New York at all. Early versions appeared in the late nineteenth century under names such as the Continental Sour before the dramatic red wine float eventually became its defining feature. Today it’s considered one of the most visually striking members of the whisky sour family—and for good reason.
Ingredients
- 60ml Ledaig Sinclair Series
- 30ml freshly squeezed lemon juice
- 20ml simple syrup
- 15ml Rioja red wine
- Ice
- Optional: egg white for a silkier texture
How to Make It
- Add the whisky, lemon juice, simple syrup and egg white (if using) to a shaker.
- Dry shake without ice if you’re using egg white.
- Add ice and shake again until well chilled.
- Strain into a rocks glass filled with fresh ice.
- Slowly pour the Rioja over the back of a spoon so it floats neatly on top.
- Sit back for a second and admire the layers before taking your first sip.
Martijn’s Twist
Most recipes call for bourbon, but I genuinely think Ledaig Sinclair Series takes this cocktail to another level. The whisky’s gentle peat never overwhelms the drink, while its Rioja cask influence ties the entire cocktail together beautifully. Pairing it with an actual Rioja float creates one of the most satisfying flavour combinations I’ve stumbled across in years.
Penicillin
The Cocktail That Proves Smoke Can Be Refreshing
The Penicillin is one of those cocktails that seems impossible on paper.
Peated whisky.
Fresh ginger.
Honey.
Lemon.
Yet somehow, they come together in perfect harmony.
It’s also one of the cocktails that converted several of my friends who claimed they didn’t like peated whisky. The smoke doesn’t dominate; instead, it acts almost like seasoning, adding depth and complexity without stealing the spotlight.
When temperatures start dropping later in the evening and everyone swaps spritzes for something with a little more character, this is usually what I reach for.
A Brief History
The Penicillin is a modern classic, created in the mid-2000s by renowned bartender Sam Ross in New York. Unlike many famous whisky cocktails that date back more than a century, the Penicillin proves that genuinely new classics are still being created. Within just a few years it had earned a place on cocktail menus all over the world.
Ingredients
- 50ml blended Scotch whisky
- 20ml fresh lemon juice
- 20ml honey-ginger syrup
- 10ml Laphroaig 10 Year Old
- Ice
- Candied ginger (optional garnish)
For the honey-ginger syrup
- 100ml honey
- 100ml hot water
- Fresh ginger, sliced
Allow the ginger to steep while the syrup cools before straining.
How to Make It
- Add the blended Scotch, lemon juice and honey-ginger syrup to a cocktail shaker.
- Fill with ice and shake vigorously.
- Strain over fresh ice into a rocks glass.
- Carefully float the Laphroaig 10 on top.
- Garnish with a piece of candied ginger if desired.
Martijn’s Twist
Most recipes simply recommend “a peated Scotch” for the float, but for me there’s only one answer: Laphroaig 10.
Its medicinal smoke, seaweed and iodine notes cut through the sweetness perfectly without becoming overwhelming. The first sip greets you with fragrant peat before slowly evolving into citrus, honey and warming ginger. It’s bold, refreshing and unmistakably whisky-driven—the very definition of letting the whisky shine.
Blood and Sand
My Favourite Version: Monkey Shoulder
The Blood and Sand is one of those cocktails that doesn’t get nearly enough love.
Perhaps it’s because the name sounds a little intimidating, or because orange juice isn’t something most whisky enthusiasts immediately associate with classic cocktails. Whatever the reason, it’s a shame, because when it’s made properly, this is one of the brightest and most balanced whisky cocktails you can drink on a warm afternoon.
The combination of citrus, cherry liqueur and sweet vermouth creates layers of fruit without becoming overly sweet, while the whisky keeps everything grounded. It almost drinks like a sophisticated summer aperitif rather than a whisky cocktail.
For me, Monkey Shoulder is the perfect choice. Its creamy malt profile and orchard fruit notes blend beautifully with the orange juice, allowing every ingredient to contribute without any single flavour dominating.
A Brief History
The Blood and Sand first appeared in The Savoy Cocktail Book in 1930 and was named after Rudolph Valentino’s silent film Blood and Sand. Unlike many classic cocktails from the era, it never achieved the same popularity as drinks like the Manhattan or Whisky Sour. That’s surprising, because few cocktails manage to balance sweet, bitter and citrus flavours quite as effortlessly.
Ingredients
- 30ml Monkey Shoulder
- 30ml sweet vermouth
- 30ml Cherry Heering
- 30ml freshly squeezed orange juice
- Ice
- Orange peel (optional garnish)
How to Make It
- Add all ingredients to a cocktail shaker.
- Fill with plenty of ice.
- Shake until thoroughly chilled.
- Double strain into a chilled coupe glass.
- Garnish with a twist of orange peel.
Martijn’s Twist
Most recipes simply say to use “blended Scotch,” but Monkey Shoulder feels as though it was created for this cocktail. Its soft vanilla, honey and ripe fruit complement the Cherry Heering perfectly, while the citrus keeps everything wonderfully refreshing. If you’re introducing someone to Scotch whisky cocktails, this is one I’d confidently place in front of them.
Geisha Martini
My Favourite Version: Suntory Toki
I’ll admit it—I only discovered the Geisha Martini a few years ago, and I immediately wondered why it isn’t far more popular.
It’s elegant without feeling pretentious, refreshing without becoming too delicate, and perhaps most importantly, it allows Japanese whisky to do exactly what Japanese whisky does best: showcase subtlety.
This isn’t a cocktail that tries to overpower your palate with sugar or heavy spices. Instead, it rewards slow sipping, making it an ideal companion for a warm summer evening as the sun begins to disappear.
Whenever I make one, I almost instinctively reach for Suntory Toki. Its crisp apple, gentle vanilla and light spice fit the drink so naturally that it almost feels like the cocktail was designed around it.
A Brief History
Unlike many of the cocktails on this list, the Geisha Martini is a relatively modern creation inspired by Japanese flavours and aesthetics rather than nineteenth-century cocktail books. It combines the clean elegance often associated with Japanese bartending with ingredients that highlight freshness and balance over intensity.
Ingredients
- 50ml Suntory Toki
- 25ml sake
- 15ml lychee liqueur
- 10ml fresh lime juice
- Ice
- Lychee or edible flower for garnish
How to Make It
- Add all ingredients to a cocktail shaker filled with ice.
- Shake until well chilled.
- Double strain into a chilled martini glass.
- Garnish with a lychee or an edible flower.
Martijn’s Twist
I’ve experimented with several Japanese whiskies in this cocktail, but I always come back to Suntory Toki. Its fresh orchard fruit, gentle oak and subtle spice never overpower the delicate lychee and sake. The result is light, elegant and incredibly easy to drink on a warm evening—exactly what a summer cocktail should be.
Journey of Brothers
My Favourite Version: Glenfiddich 12 Year Old
This is probably the least familiar cocktail on this list, but it absolutely deserves more attention.
The first time I came across the Journey of Brothers, I wasn’t expecting much. Yet after one sip I knew this wasn’t another cocktail trying to disguise whisky behind layers of fruit and sugar. Instead, it celebrates the whisky, allowing fresh citrus and herbal notes to lift rather than hide the spirit.
It feels modern, vibrant and wonderfully refreshing while still tasting unmistakably like whisky.
That’s exactly why I love it.
For this cocktail, I always reach for Glenfiddich 12. Its signature pear and apple character provides a bright backbone that immediately makes the drink feel summery, while its gentle oak keeps everything beautifully balanced.
A Brief History
The Journey of Brothers is a contemporary whisky cocktail inspired by the idea of bringing together different traditions and flavours in one harmonious serve. While it doesn’t have the century-old pedigree of classics like the Sazerac or Blood and Sand, it reflects today’s cocktail culture, where creativity and quality ingredients take centre stage.
Ingredients
- 50ml Glenfiddich 12 Year Old
- 20ml elderflower liqueur
- 20ml fresh lemon juice
- 10ml honey syrup
- 2 dashes orange bitters
- Ice
- Lemon twist
How to Make It
- Add all ingredients to a shaker filled with ice.
- Shake vigorously for around fifteen seconds.
- Double strain into a chilled coupe glass.
- Express the oils from a lemon twist over the drink before garnishing.
Martijn’s Twist
Some cocktails call for bold, powerful whiskies. This isn’t one of them.
Glenfiddich 12’s delicate orchard fruit and honey notes allow the elderflower to shine without becoming floral overload. The orange bitters add just enough depth to stop the cocktail drifting into sweetness, creating a drink that’s incredibly refreshing while remaining unmistakably Scotch. It’s one of those cocktails that quietly surprises people—and often ends up becoming their favourite of the evening.
Mint Julep
My Favourite Version: Woodford Reserve Double Oaked
If there is one whisky cocktail that truly deserves the title of summer classic, it’s the Mint Julep.
Served ice cold, packed with crushed ice and bursting with fresh mint, it’s the kind of drink that instantly cools you down on a hot afternoon. It’s no coincidence that it has become synonymous with the Kentucky Derby, where thousands are enjoyed every year under the spring sunshine.
Many recipes recommend a classic bourbon, and that certainly works, but I like my Mint Julep with a little more depth. Woodford Reserve Double Oaked brings layers of vanilla, toasted oak and caramel that remain beautifully present even as the crushed ice slowly melts.
A Brief History
The Mint Julep dates back to the eighteenth century in the southern United States, where it was originally enjoyed as a refreshing morning drink—believe it or not, sometimes even before breakfast. By the late nineteenth century it had become closely associated with Kentucky bourbon, and today it’s considered one of America’s most iconic whisky cocktails.
Ingredients
- 60ml Woodford Reserve Double Oaked
- 10ml simple syrup
- 8–10 fresh mint leaves
- Crushed ice
- Fresh mint sprig for garnish
How to Make It
- Lightly muddle the mint leaves with the simple syrup in the bottom of a julep cup or rocks glass.
- Fill the glass halfway with crushed ice.
- Add the bourbon and stir until the outside of the glass begins to frost.
- Top with more crushed ice to create a small mound.
- Garnish generously with a fresh mint sprig.
Martijn’s Twist
Many people save Double Oaked for drinking neat, but I actually think it makes one of the finest Mint Juleps imaginable. As the ice slowly melts, new layers of vanilla, toasted marshmallow and caramel emerge, making every sip slightly different from the last. It’s rich enough to remain unmistakably bourbon while still feeling wonderfully refreshing.
Sazerac
My Favourite Version: Sazerac Rye
Some cocktails are refreshing.
Others are iconic.
The Sazerac somehow manages to be both.
This isn’t the sort of cocktail I’d order while sitting by the pool in the blazing afternoon sun. Instead, it’s the drink I pour as the barbecue winds down, conversations become a little quieter and the evening begins to cool. It has more intensity than most cocktails on this list, yet thanks to the absinthe rinse and bright lemon oils it never feels heavy.
If you’ve never made one before, don’t let its reputation intimidate you. It’s surprisingly straightforward once you’ve mastered the technique.
A Brief History
Often considered America’s oldest cocktail, the Sazerac was born in New Orleans during the nineteenth century. Originally made with Cognac, it gradually evolved into the rye-based version we know today after American rye whisky became more widely available. Its distinctive absinthe rinse gives the cocktail its unmistakable aromatic character and has helped make it one of the world’s true cocktail legends.
Ingredients
- 60ml Sazerac Rye
- 1 sugar cube (or 10ml simple syrup)
- 2 dashes Peychaud’s Bitters
- Absinthe
- Lemon peel
How to Make It
- Chill a rocks glass and rinse it with a small amount of absinthe before discarding the excess.
- In a separate mixing glass, muddle the sugar cube with the bitters (or simply combine the syrup and bitters).
- Add the rye whisky and plenty of ice.
- Stir until well chilled.
- Strain into the prepared glass.
- Express the oils from a lemon peel over the drink and discard the peel or use it as garnish.
Martijn’s Twist
Some cocktails invite experimentation.
The Sazerac isn’t really one of them.
For me, Sazerac Rye simply belongs in a Sazerac. Its peppery spice, gentle sweetness and herbal notes feel perfectly at home alongside Peychaud’s Bitters and absinthe. Sometimes the classic choice really is the best one.
Ronan Collins
My Favourite Version: Jameson
Every list needs one cocktail that proves whisky doesn’t have to be complicated.
The Ronan Collins is exactly that.
Bright, crisp and incredibly easy to drink, it’s the cocktail I often recommend to people who normally order a gin and tonic or a vodka soda. Irish whiskey’s naturally approachable style makes it an ideal foundation for a long, refreshing drink that still delivers plenty of character.
And if there’s one bottle that’s almost always within arm’s reach when I’m mixing one, it’s Jameson.
Reliable?
Absolutely.
Boring?
Not even close.
A Brief History
The Ronan Collins is a modern Irish interpretation of the classic Tom Collins, replacing gin with Irish whiskey while retaining the refreshing citrus-forward style that made the original famous. It showcases exactly why Irish whiskey has become such a popular choice in contemporary cocktail bars: it’s smooth enough to welcome newcomers yet flavourful enough to satisfy experienced whisky drinkers.
Ingredients
- 50ml Jameson Irish Whiskey
- 25ml fresh lemon juice
- 15ml simple syrup
- Chilled soda water
- Ice
- Lemon wheel
How to Make It
- Fill a Collins glass with plenty of ice.
- Add the Jameson, lemon juice and simple syrup.
- Stir briefly.
- Top with chilled soda water.
- Garnish with a lemon wheel.
Martijn’s Twist
This cocktail reminds me that not every great whisky drink needs to be complicated. Jameson’s gentle orchard fruit, vanilla and subtle spice make it wonderfully refreshing without ever losing its Irish whiskey identity. Sometimes simplicity really is the ultimate luxury—especially on a warm summer afternoon.
My Final Thoughts on Summer Whisky Cocktails
One of the biggest misconceptions about whisky is that it’s only a drink for dark winter evenings, roaring fireplaces and heavy armchairs.
I couldn’t disagree more.
While I still love ending a summer’s day with a neat dram under the stars, these cocktails prove that whisky deserves a place in the sunshine just as much as any other spirit. They don’t hide the whisky behind endless syrups or fruit juices; they celebrate what makes it unique, whether that’s the smoky coastal character of Laphroaig, the elegant subtlety of Suntory Toki or the creamy maltiness of Monkey Shoulder.

After all, whisky is far more versatile than many people realise. Neat, with a splash of water or shaken into a beautifully balanced cocktail, there’s no wrong way to enjoy it—as long as the whisky still gets the chance to tell its story.
Which one would I make first?
Without hesitation, the smoky New York Sour.
If you only try one cocktail from this list before summer ends, make it that one.
