New York Sour
The New York Sour is a whiskey sour wearing a cape of claret, and like several things named for New York it comes from Chicago. Bartenders there were floating red wine on whiskey sours by the 1880s under names like the Continental Sour and the Southern Whiskey Sour; the drink drifted east, and New York, as is its custom, kept the credit. Whatever the byline, the idea has survived a hundred and forty years because it is a genuinely brilliant one. The float is architecture, not decoration. Fifteen millilitres of dry red wine poured over a spoon sits on the sour in a distinct crimson stratum, and the drink is deliberately served unmixed: the first sips arrive through wine, tannic and dark-fruited, the middle blends the two, and the finish is pure sour. One glass, three acts, no extra effort beyond a slow pour. Underneath, the spec is a classic rye sour with the optional egg white turning the wine float into a still life: crimson over silk over amber. It is among the most photographed drinks of the revival for exactly that reason, and among the most satisfying for better ones.

Ingredients
60ml
The foundation: rye keeps the sour dry enough to argue with the wine’s fruit. Bourbon makes a rounder, sweeter reading.
30ml
A full sour measure, running above the syrup rather than level with it, and calibrated before the wine adds its own dry fruit above. Squeeze it to order: the wine float exposes a tired citrus the way nothing else in the sour family does.
22.5ml
The balance for the lemon, calibrated before the wine adds its own dry fruit above.
A few drops
Optional silk: dry-shaken, it gives the wine float a white platform and the drink its famous three-layer look.
15ml
The cape: fifteen millilitres of syrah or malbec floated over a spoon, sitting as a crimson stratum. Presence over pedigree; last night’s open bottle is the traditional source.
Instructions
Add the rye, lemon juice, simple syrup and egg white, if using, to a shaker without ice.
Dry shake for 10 seconds if using the egg white; otherwise proceed.
Add ice and shake hard for 10 to 12 seconds.
Strain into a rocks glass over fresh ice.
Float the red wine by pouring it slowly over the back of a bar spoon held at the surface.
Serve unstirred, and let the drinker find the layers.

Expert Tip
The float wants a slow hand and a full spoon. Hold a bar spoon inverted with its back just touching the surface of the drink and pour the wine down it in a thin ribbon; it will spread out and sit as a clean crimson stratum. Poured straight in it punches through, and you get the mauve compromise nobody ordered. Fifteen millilitres is the measure and it is enough. More wine and the layer thickens until the sour underneath is a rumour; less and the colour goes patchy. If you are using the egg white, dry shake first and let the foam settle for twenty seconds before floating. Wine sits far more cleanly on silk than on liquid, and the crimson-on-white-on-amber result is the whole reason the drink is photographed as often as it is.
Behind the New York Sour
Flavour Profile
The Origin
The recipe appears in the 1880s as the Continental Sour, a Chicago speciality of floating red wine on a whiskey sour, and travels through the bar books under shifting names until New York’s stuck. The claret float was a Gilded Age flourish, wine being the era’s prestige ingredient, and the drink is one of the few survivors of that fashion because the flourish turned out to be functional.
The Wine
A dry, fruit-forward red with some grip is the right float: a syrah or malbec brings dark fruit and enough tannin to read against the citrus, while anything oaky or delicate disappears. The wine does not need to be fine, it needs to be emphatic, and an open bottle from dinner is the traditional and correct source.
The Float Technique
Wine is lighter than the shaken sour beneath it, so the float is physics plus patience: bar spoon inverted at the surface, wine poured in a thin ribbon over its back, glass held still. Over egg-white silk the wine sits even more cleanly, and the crimson-on-white-on-amber result is the drink’s calling card.
How to Serve It
Unstirred, always: the drink is designed as a descent through wine into sour, and mixing it produces a mauve compromise nobody ordered. Rye is the classic engine and keeps the middle act dry; bourbon makes a softer, rounder version. Serve it to wine drinkers as an ambush and to whiskey drinkers as a holiday.
Why Wine Works on a Sour
The float is not simply decorative, and the reason is that wine and a whiskey sour want the same things from each other.
A sour is bright, sharp and slightly sweet, with nothing tannic in it. Red wine brings tannin and dark fruit, which are exactly the two registers the sour lacks. Drunk together they read as a fuller drink; drunk in sequence, which is what the float arranges, they read as a progression from dry and grippy to sharp and clean.
That is why it survived when most Gilded Age flourishes did not. Floating something on a drink for the look of it goes out of fashion. Floating something that fixes a genuine gap in the drink underneath does not.
Choosing the Bottle
The wine needs presence rather than pedigree, which is a genuinely useful thing about this drink: it is one of very few cocktails improved by last night's open bottle.
Dry and fruit-forward with some grip is the specification. Syrah, malbec and a young Rioja all work. What does not work is anything delicate or heavily oaked: a fine Burgundy disappears entirely under lemon and rye, and an oak-heavy red turns the finish woody and confused.
Fifteen millilitres a drink also means a bottle goes a very long way, which is the practical argument for keeping something cheap and emphatic rather than opening something good.

The Spirit
Whiskey (Rye)The whiskey the American classics were written for. Rye is dry and peppery where bourbon is sweet and broad, and a Manhattan or a Sazerac built on the wrong one is a noticeably different drink rather than a near miss.

Whiskey Sour
The Whiskey Sour is one of the oldest documented cocktails in the American canon, printed in Jerry Thomas’s 1862 bar guide, and its structure of whiskey, fresh lemon and sugar is the template every other whiskey sour derives from. The Honey Sour changes the sweetener. The Penicillin changes the sweetener and the technique. The Amaretto Sour changes the base spirit. Understand this drink and the whole family becomes readable. The egg white question matters more here than in most sours, because both versions are widely ordered and both are correct. With it, the drink is a Boston Sour: silky, with the foam carrying the bourbon’s vanilla to the nose before the lemon reaches the palate. Without it, sharper and more direct. Pre-made sour mix has shown a generation this drink at its worst. Built with lemon squeezed to order, a decent bourbon and a properly proportioned syrup, it surprises almost everyone whose expectations were formed by the imitation.
Gold Rush
The Gold Rush was invented at Milk and Honey, the Lower East Side bar that rewrote modern cocktail culture, when T.J. Siegal asked Sasha Petraske for a whiskey sour and got talked into honey instead of sugar. That was 2001, the drink went around the world with the bar’s alumni, and it is now as close to a canonical modern classic as the twenty-first century has produced: bourbon, lemon, honey, done. The honey is the entire intervention and it changes everything: floral weight where sugar is neutral, a waxy richness that rounds bourbon’s corners, and a golden colour that named the drink. Cut into syrup at two parts honey to one part water it integrates like sugar never quite does, and the drink lands somewhere between a whiskey sour and a warm afternoon. Its family tree runs in both directions: back to the Bee’s Knees, the Prohibition gin sour that proved honey and citrus belonged together, and sideways to the Penicillin, Milk and Honey’s other golden child, which is a Gold Rush that emigrated to Islay. Three ingredients, no technique beyond a hard shake, and no excuse for a bad one ever.
Penicillin
The Penicillin was created by Sam Ross at Milk & Honey in New York in 2005 and is one of the most significant original cocktails of the contemporary revival. Ross also created the Paper Plane; the Penicillin is the more complex and more demanding of the two. The structure is a whisky sour built on blended Scotch, sweetened with honey syrup and given its heat by fresh ginger shaken in alongside it, with a float of Lagavulin 16 over the surface. Honey and ginger together define the drink's character, combining floral sweetness with a sharp, spiced bite. The blended Scotch supplies the base, and the float supplies the peated smoke that the blend alone could not deliver at the volume a balanced sour requires. The float is the technique most commonly misapplied. Poured correctly it sits as a distinct aromatic layer, met at the nose and on the first sip before integrating gradually into the drink below.
