What Is a Whiskey Sour
A whiskey sour is a shaken cocktail built on three things: whiskey, fresh citrus, and a sweetener. That is the entire foundation. Everything else, the egg white, the garnish, the choice of whiskey, is a variation on this base. It belongs to the sour family of cocktails, the same group that gives you a Pisco Sour or an Amaretto Sour, where a spirit is balanced against something tart and something sweet until the three stop fighting each other and start working together.
The drink dates back to the mid-1800s and has stayed near the top of every classic cocktail list since, mostly because it is forgiving. You do not need a bar cart full of liqueurs. You need decent whiskey, real lemons, and ten minutes.
Whiskey Sour Ingredients
The full recipe needs very little, and each ingredient earns its place.
- Whiskey: 60ml (2 oz). Bourbon is the traditional choice because its vanilla and caramel notes soften the citrus, but rye and blended Scotch both work.
- Fresh lemon juice: 22-25ml (0.75-1 oz). Bottled juice will not give you the same brightness. Squeeze it fresh.
- Simple syrup: 15-22ml (0.5-0.75 oz). Equal parts sugar and hot water, stirred until clear, then cooled.
- Egg white (optional): one small egg white, or 15-20ml pasteurized liquid egg white.
- Angostura bitters and a cherry or lemon twist for garnish.
That is the entire ingredient list. No juicer required, no obscure liqueur, nothing that needs a special trip to the store.
Classic Whiskey Sour Recipe (Step by Step)
Ingredients
- 60ml bourbon whiskey
- 22ml fresh lemon juice
- 15ml simple syrup
- Ice cubes
- Cherry or orange peel for garnish
Method
- Fill a cocktail shaker with ice.
- Add the bourbon, lemon juice, and simple syrup.
- Shake hard for 12-15 seconds until the shaker feels cold to the touch.
- Strain into a rocks glass over one large ice cube, or into a chilled coupe with no ice.
- Garnish with a cherry, an orange peel, or a few drops of bitters on top.
That is the whole recipe. Total time is under five minutes, and it scales cleanly if you are making a round for guests, just multiply every measurement by the number of drinks.
Whiskey Sour Recipe With Egg White
Adding egg white does not change the flavor much. What it changes is texture. It gives the drink a thick, silky foam on top and a smoother mouthfeel throughout, closer to a dessert than a straight spirit drink. This version is sometimes called a Boston Sour.
What to add
Use one small egg white per serving, or about 15-20ml of pasteurized liquid egg white if you would rather skip raw egg.
The dry shake technique
This is the one step people get wrong. Egg white needs to be shaken twice.
- Add the whiskey, lemon juice, syrup, and egg white to the shaker without ice. Shake hard for 15 seconds. This is the dry shake, and it is what builds the foam.
- Open the shaker, add ice, and shake again for another 15 seconds to chill the drink.
- Strain into a chilled glass. The foam should sit on top in a clean, stable layer.
- Drop three or four dashes of Angostura bitters onto the foam and drag a toothpick through them for a simple design, or just leave it plain.
Skipping the dry shake is the most common mistake with this version. Shake with ice first and the foam never fully forms.
Whiskey Sour Recipe No Egg
If you would rather skip egg altogether, whether for taste, allergies, or a vegan kitchen, you have two solid options.
Option 1: Skip it entirely
The classic recipe above was built without egg white for most of its history. Whiskey, lemon, syrup, shaken hard and strained, is a complete drink on its own. You lose the foam, not the flavor.
Option 2: Use aquafaba
Aquafaba, the liquid drained from a can of chickpeas, foams almost exactly like egg white when shaken. Use 15-20ml in place of the egg white and follow the same dry shake method above. Most people cannot tell the difference once bitters go on top.
Either way, this version keeps everything about the classic recipe except the foam, so it is the one to use if you are short on time or ingredients.
Simple Whiskey Sour Recipe (2-Ingredient Shortcut)
For a genuinely simple version with almost no prep, replace the lemon juice and simple syrup with sour mix or a bottled lemonade.
- 60ml whiskey
- 90ml good quality lemonade or sour mix
Shake with ice and strain, or build it directly in a glass over ice and stir. It will not have the same sharp balance as the fresh-juice version, but it takes under a minute and needs no separate syrup.
What Whiskey to Use in a Whiskey Sour
Bourbon is the standard choice because its sweetness carries the citrus without turning sharp. A few options work particularly well, depending on budget and what is available in India.
| Whiskey | Style | Why it works in a sour |
|---|---|---|
| Wild Turkey 101 | Bourbon | High proof holds up against citrus and syrup without getting lost |
| Maker's Mark | Wheated bourbon | Soft, rounded sweetness, an easy entry point for a first sour |
| Jack Daniel's Old No. 7 | Tennessee whiskey | Charcoal-mellowed profile that pairs cleanly with lemon |
| Jim Beam White | Bourbon | Budget-friendly and reliable for everyday mixing |
| Royal Stag | IMFL whisky | Affordable local option for a lighter, easy-drinking sour |
If bourbon is not available or you want to try a variation, rye whiskey gives a spicier, drier sour, and a blended Scotch like the ones covered in our guide to the best whisky for cocktails will also hold up well.

The Whiskey Sour Ratio
Most sour cocktails follow a rough 2:1:0.75 ratio, two parts spirit, one part citrus, three-quarters part sweetener. This is a starting point, not a rule. Lemons vary in sharpness, so taste as you go and adjust the syrup up or down by a few milliliters until the tartness and sweetness sit evenly against the whiskey. A sour that tastes flat usually needs more lemon. One that tastes harsh usually needs a touch more syrup.
Common Mistakes to Avoid
- Using bottled lemon juice. It tastes flat and slightly bitter compared to fresh juice.
- Under-shaking. A whiskey sour needs a hard 12-15 second shake to properly chill and dilute. A gentle stir will not do it.
- Skipping the dry shake with egg white. Ice added too early prevents the foam from forming.
- Too much syrup. A sour should taste bright, not like dessert. Start light and add more if needed.
- Serving it too warm. Use fresh ice for shaking and, if serving on the rocks, a fresh large cube rather than the shaker ice.
Variations Worth Trying
Once the base recipe is comfortable, a few well-known variations are worth exploring.
- New York Sour: the classic recipe with a small float of red wine on top, poured gently over the back of a spoon.
- Boston Sour: the same as the egg white version above, the name is used interchangeably in many bars.
- Gold Rush: whiskey, lemon juice, and honey syrup instead of simple syrup, served over one large rock with no shaking of egg.

Calories and ABV
A standard whiskey sour made with 60ml of 40% ABV whiskey, fresh lemon juice, and simple syrup runs to roughly 160-180 calories per serving, most of it from the syrup and the whiskey itself. Skipping the egg white does not meaningfully change the calorie count since egg white contributes very little. For a full breakdown of how alcohol content affects a drink like this, see our guide on whisky and calories and what ABV really tells you.
Serving and Garnish Tips
Serve in a rocks glass over one large ice cube for the classic version, or in a chilled coupe with no ice for the egg white version, since the foam holds better without ice diluting it. A brandied cherry or an orange peel, expressed over the glass to release the oils, is the standard garnish. For the egg white version, three or four dashes of Angostura bitters on the foam, dragged into a simple pattern with a toothpick, finishes the drink without needing any special bar tools.
Frequently Asked Questions
What whiskey is best for a whiskey sour?
Bourbon is the most common choice because its natural sweetness balances the lemon juice. Rye whiskey works well too, giving a spicier, drier result.
Can I make a whiskey sour without egg white?
Yes. The classic whiskey sour recipe of whiskey, lemon juice, and simple syrup does not require egg white at all. It only changes the texture, not the core flavor, so leaving it out is completely standard.
What can I use instead of egg white in a whiskey sour?
Aquafaba, the liquid from a can of chickpeas, foams in almost the same way as egg white when shaken and works as a direct vegan substitute.
Why is my whiskey sour not foamy?
The egg white needs a dry shake first, shaken without ice for about 15 seconds, before adding ice and shaking a second time. Adding ice too early stops the foam from forming.
What is the ratio for a whiskey sour?
A standard ratio is 2:1:0.75, two parts whiskey, one part fresh lemon juice, three-quarters part simple syrup. Adjust slightly based on how tart your lemons are.
Is a whiskey sour the same as a Boston sour?
They are effectively the same drink. Boston sour is simply the name commonly used for the version made with egg white.
Final Verdict
The whiskey sour earns its place as a classic because it does not depend on rare ingredients or bartending experience. A bottle of bourbon, fresh lemons, and a bit of syrup gets you the full drink. Add egg white if you want the silky texture, skip it if you want a faster pour, and adjust the ratio to match your own taste for tart versus sweet. Once the base recipe is second nature, every variation on this list becomes a five-minute project instead of a new drink to learn from scratch.
