There’s something about a Scotch Sour that just feels right — bright, smoky, and smooth, all in one sip. It’s the kind of cocktail that’s easy to love and even easier to whip up once you know a few simple tricks. I thought I’d share one of my favorite after-dinner cocktails with you — it’s been my go-to for cozy evenings and small get-togethers alike.
Scotch Sour
Ingredients
You’ll need:
- 2 oz (60ml) Scotch whisky
- ¾ oz (22ml) fresh lemon juice
- ½ oz (15ml) simple syrup
- 1 egg white (optional, for a silky froth)
- Ice cubes (enough to fill a shaker)
Equipment:
- Cocktail shaker
- Strainer
- Old Fashioned glass (or any short, sturdy glass)
Prep Time & Servings
- Prep Time: 5 minutes
- Serves: 1
Method
- First things first — chill your glass. Pop it in the freezer while you mix.
- Fill your cocktail shaker about halfway with ice.
- Pour in the Scotch whisky, lemon juice, and simple syrup.
- If you’re feeling fancy (and want that gorgeous foam), crack in the egg white.
- Now, shake it like you mean it! Give it a good, strong shake for about 15 seconds — you want it icy cold and a little frothy.
- Strain the drink into your chilled glass. It should look smooth and inviting, with a light frothy top if you used egg white.
- Optional: Garnish with a lemon twist or a cherry for a little extra flair.
Tips for the Best Scotch Sour
- Use fresh lemon juice — bottled just doesn’t have the same zing.
- Shake hard if you’re using egg white. It needs that energy to whip up into that signature froth.
- Taste before you pour — if you like it sweeter, add a tiny splash more syrup.
Storage Instructions
Scotch Sours are best enjoyed fresh. If you absolutely must prep ahead, mix everything except the egg white and keep it in the fridge for up to 24 hours. Shake with ice and egg white (if using) just before serving.
Ingredient Swaps
- No simple syrup? Use honey or agave syrup — just thin it with a little warm water first.
- Vegan? Swap the egg white for 2 tablespoons of aquafaba (the liquid from a can of chickpeas). It froths up beautifully!
- Want it a little richer? Try maple syrup instead of simple syrup for a cozy, autumn twist.
What to Expect
The first sip hits you with a bright lemony pop, quickly followed by the smoky warmth of the Scotch. There’s just enough sweetness to round it all out. It’s smooth, refreshing, and a little bit fancy without trying too hard. I’ve made this drink countless times, and here’s a tip I learned along the way: a slightly less peaty Scotch (like a good blended one) makes the best, most balanced sour.
Food Pairings
A Scotch Sour loves good company. Try it with:
- Smoked salmon: The smoky flavors are a match made in heaven.
- Barbecue ribs: Sweet, sticky ribs and a tart cocktail? Yes, please.
- Dark chocolate: A little square of good chocolate after a sip is pure magic.
Variations to Try
Smoky Scotch Sour
- Use a peaty Islay Scotch for a deeper, smoky flavor.
- Garnish with an orange twist to brighten it up.
Spiced Scotch Sour
- Muddle a cinnamon stick and a couple of cloves with the syrup before shaking.
- Great for chilly nights when you want a little spice.
Herbal Scotch Sour
- Infuse your simple syrup with rosemary or thyme.
- Adds an earthy, savory twist that’s really special.
Light & Fizzy Scotch Sour
- Top your finished drink with a splash of soda water.
- Perfect for when you want something a bit lighter and more refreshing.
Common Questions
What’s the best Scotch to use?
Go for a blended Scotch that’s smooth and not too smoky. Save the heavy peaty ones for sipping neat.
Can I make a big batch?
Absolutely! Just multiply the ingredients by the number of servings. Skip the egg white if you’re batching — it’s easier that way. Shake individual servings with egg white if you still want that frothy top.
Can I make it vegan?
Yes! Use aquafaba instead of egg white — it’s a fantastic plant-based swap and froths up like a dream.
How long should I shake it?
About 15 seconds should do it. The shaker should feel freezing cold to the touch, and you should hear a satisfying slosh.
Can I save leftovers?
It’s really best fresh, but if you must, you can keep it in the fridge for a day. Stir well before drinking.
How many calories are in a Scotch Sour?
Roughly 200 calories per serving. You can cut back a bit by using less syrup or swapping to a sugar-free option.
Serving Suggestions
Serve your Scotch Sour in a chilled Old Fashioned glass with a lemon twist for a classic touch. If you’re feeling fancy, a cherry on top never hurt anyone. It’s a great drink to kick off a dinner party or to sip slowly on a quiet evening.
If you’re planning a party, pair it with a simple cheese board or smoky appetizers to really let the drink shine. And if you want a little dessert pairing? A rich chocolate tart or a handful of roasted nuts would be just the thing.
A Scotch Sour is one of those cocktails that’s endlessly satisfying — simple, stylish, and a little surprising. Once you master it, you’ll find yourself coming back to it again and again, just like I have. Cheers!
