Whiskey Sour Techniques
Three ingredients and a hard shake — a Whiskey Sour is simple to make and easy to make badly. The shake, the dry shake, the ratio, the fresh juice, the strain, and the few words that get you a real one at a bar.

A Manhattan forgives nothing and an Old Fashioned forgives almost everything; the Whiskey Sour sits between them. The lemon and sugar hide a great deal — a slightly soft whiskey, an imperfect pour — but they expose two things without mercy: juice that isn't fresh and a shake that wasn't hard enough. Add egg white and a third skill arrives, because foam has to be built on purpose. The difference between a bar-quality sour and a flat, thin or weeping one is technique, and technique is what this hub teaches.
The skills are above as individual guides; what follows is the order to learn them in and the single page each one replaces.
The Core Skills, in Order
Foundation TechniqueHow to Make a Whiskey Sour (Step-by-Step Method)
Start here. Juice the lemon, measure 2 : ¾ : ¾, shake hard on plenty of ice, strain over fresh ice or into a chilled coupe, garnish — with the mistakes that undo most home sours.
The Skill That Matters MostHow to Shake a Whiskey Sour
How hard, how long, what ice — and for egg white, the dry shake, the reverse dry shake, the blender shortcut and why you double strain.
CalibrationWhiskey Sour Ratios Explained
2 : ¾ : ¾, Difford's 6:3:2, the IBA's 45 : 25 : 20 and the drier 2 : ¾ : ½ — what each does, and how proof, syrup strength and egg white decide which to use.
The Optional Ingredient Everyone Argues AboutEgg White in a Whiskey Sour
What it does, how much (about ½ oz), pasteurized eggs and the FDA's advice, and the aquafaba and foamer substitutes.
The Ingredient Most People Get WrongFresh Lemon Juice
Why every spec says fresh, why sour mix ruined the drink for two decades, and how a few hours' rest helps while a day's wait hurts.

Spirit, serve, egg white — the three decisions in one sentence, and how to tell whether the bar squeezes lemons or pours from a bottle before you commit.
The Five-Minute Checklist
If you only remember one list, make it this one. Each line is a page above; together they are the whole technique.
- Juice the lemon the same day. A few hours' rest in the fridge is fine; past about six it turns bitter.
- Measure. 2 oz rye, ¾ oz lemon, ¾ oz 1:1 syrup (or ½ oz rich). Jigger, not free-pour — the balance lives in a quarter-ounce.
- Decide on egg white. About ½ oz, pasteurized, or 1 oz aquafaba — or none. Thomas's 1887 recipe had none; the IBA calls it optional.
- Shake hard on plenty of ice until the tin frosts and hurts to hold. With egg white, add a shake without ice — before (dry shake) or after (reverse dry shake).
- Strain over fresh ice in a rocks glass, or fine strain into a chilled coupe.
- Garnish — lemon wheel and cherry on the rocks; lemon twist and dashes of Angostura on the foam up.

The Three Shakes
Egg white is where sour technique divides, and the published record is unusually clear about the trade-offs. The dry shake — all ingredients shaken without ice first, then with ice — is Julie Reiner's method: about ten shakes over ten seconds, which she finds gives smaller bubbles and better mouthfeel. The reverse dry shake — shake with ice, strain the ice out, shake again without — is the order Difford's uses for its Whiskey Sour, Boston Sour, New York Sour and Rattlesnake, and a Tales of the Cocktail test found it produced the firmest, most meringue-like head, because the foam is built last and ice never gets a chance to break it down; bartenders quoted by PUNCH note the costs, larger bubbles (Reiner) and a head that settles faster (Ray Keane). Then there are the dissenters: Rob Krueger skips the dry shake entirely and relies on proper ice and a hard shake, Steve Schneider shakes egg drinks with a single 2-by-2-inch cube, Ray Keane blends, and Jeffrey Morgenthaler froths the egg white with an immersion blender before an ordinary iced shake. Tristan Stephenson's warning applies to all of them: over-shake without ice and you get an absurdly foamy drink. Aquafaba needs longer — 10 to 12 seconds dry against roughly six for egg. The full comparison is in how to shake a Whiskey Sour.
Technique needs a rye with the proof to survive the shake — scored and ranked.

Everything here carries to the sour's relatives. A Boston Sour is the egg-white technique in full; a New York Sour adds one skill, floating wine over the back of a spoon; a Gold Rush is the plain shake with honey syrup and a large rock; a Whiskey Smash swaps juicing for muddling. The stirred side of the whiskey bar — the Manhattan's thirty-second stir, the Old Fashioned's rock — is its own hub at Manhattan Techniques and Old Fashioned Techniques; the shared physics is in the science of cocktail dilution. Every ingredient behind the technique is in the Ingredients Guide.
Tools Worth Owning
- A two-piece shaking tin (or a cobbler shaker). Weighted tins seal better and open cleanly after an egg-white shake. Shop.
- Hawthorne strainer plus a fine mesh strainer. Difford's fine-strains every serve; it keeps ice shards and lemon pulp out of the glass.
- A jigger with ¼ oz marks. The sour's balance lives in a quarter-ounce of syrup.
- A citrus press. A hand press juices a lemon in seconds and leaves the bitter pith behind.
- Rocks glasses and 5–6 oz coupes. Shop.
- Large ice. Big, dry cubes from a silicone tray chill hard without over-diluting; crushed ice belongs only in the Smash.
- An immersion blender or small whisk if you make egg-white sours often — Morgenthaler's shortcut to a stable foam.
Frequently Asked Questions
What is the most important technique for a Whiskey Sour?
The shake: hard, on plenty of ice, until the tin frosts. It chills, dilutes and integrates the lemon, syrup and whiskey at once — and with egg white, it builds the foam.
Should a Whiskey Sour be shaken or stirred?
Shaken, always. It contains citrus (and sometimes egg white), which need the aeration and hard chill of a shake. Stirring is for spirit-and-vermouth drinks like the Manhattan.
What is a dry shake?
Shaking the ingredients without ice first so the egg white emulsifies into foam, then adding ice and shaking again. About ten shakes over ten seconds is Julie Reiner's rule of thumb.
What is a reverse dry shake?
Shaking with ice first, straining the ice out, then shaking again without ice. Because ice breaks foam down, building the foam last gives the firmest, most meringue-like head — at the cost of larger bubbles.
Why does my Whiskey Sour taste flat?
Almost always the lemon. Bottled juice and sour mix lack the brightness of fresh juice and often carry preservatives. Juice the lemons the same day; a few hours' rest is fine, a day's is not.
Do I need to double strain a Whiskey Sour?
For the up serve, yes — a fine mesh strainer over the Hawthorne keeps ice shards and pulp off the foam. After a reverse dry shake no final strain is needed, because the ice has already been removed.
Frequently Asked Questions (Voice Search)
How long do you shake a Whiskey Sour?
Until the tin is frosted and painfully cold — hard and brief rather than long and gentle. With egg white, add a roughly ten-second shake without ice before or after.
What is the ratio for a Whiskey Sour?
2 : ¾ : ¾ — two ounces of whiskey to three-quarters of an ounce each of fresh lemon juice and simple syrup. Difford's prefers 2 : 1 : ⅔ with rich syrup.
How do you order a Whiskey Sour?
Say the spirit, the serve and the egg: "Rye Whiskey Sour, up, with egg white." Ask whether they use fresh lemon — if the answer is sour mix, order something else.
What glass is a Whiskey Sour served in?
A rocks glass over fresh ice, or a chilled coupe served up — the coupe especially for egg-white versions, since foam breaks down faster on ice.
