New York Sour: How to Float Red Wine on a Whisky Sour, Three Ways
Whisky Clan cocktail guide | 5 November 2026 | Serves one per recipe | Adults of legal drinking age only
A ruby-red stripe over a golden whisky sour makes the New York Sour look theatrical, but the flavour change is the real reason to learn it. The dry red wine brings dark fruit, tannin and a little extra acidity; the lemon provides lift; and the choice of whisky determines whether the drink feels rounded, peppery or gently smoky. We'll make the recognised classic, compare bourbon with rye, and then try a clearly labelled Whisky Clan Scotch-inspired adaptation. A softer Irish whiskey swap is included, too.

What is a New York Sour?
At its simplest, a New York Sour is a whiskey sour topped with a small, carefully poured layer of dry red wine. The International Bartenders Association (IBA) specifies 60 ml rye whiskey or bourbon, 30 ml fresh lemon juice, 22.5 ml simple syrup and a 15 ml red-wine float, with a few drops of egg white as an optional element. That is our reference standard, not a claim that every bar uses the same formula.
The wine goes on last, so your first sip catches its fruit and tannic edge before the drink gradually integrates. It is not simply a whisky sour made purple by shaking everything together. A float works best when the base is properly chilled and the wine is added very gently.
What to have ready
Equipment: a 30/60 ml jigger, cocktail shaker, Hawthorne strainer (fine strainer optional), bar spoon, citrus juicer and vegetable peeler. Glass: a chilled old-fashioned/rocks glass, around 250–300 ml capacity. Ice: plenty for shaking plus one fresh large cube or several clean solid cubes for serving. Yield: one cocktail per recipe; roughly 125–145 ml of liquid before dilution, depending on the formula, plus ice. Dilution during shaking will increase the actual volume.
Simple syrup, 1:1: dissolve equal weights of white sugar and water (for example, 50 g of each), cool, cover and refrigerate promptly. Make small quantities and discard if appearance or smell changes. Always measure lemon juice freshly: bottled lemon can be less lively and may alter acidity.
Why the origin story is more complicated than the name
Despite the New York name, the red-wine-topped whiskey sour appears in reporting from Chicago in the 1880s. Cocktail historian David Wondrich, writing for The Oxford Companion to Spirits & Cocktails, cites a 25 November 1883 Chicago Tribune reference to claret added to a whiskey sour, and notes that the New York Sour name was already attested in Boston by December 1885. Other names attached to related drinks included Continental and Southern Sour.
Some contemporary histories instead highlight the drink's appearance under the New York Sour name in the widely circulated 1934 Old Mr. Boston guide. These statements need not mean the drink was invented in 1934: early evidence, different names and later popular printed recipes are separate questions. The original bartender is not securely established. Nor should the Scotch version below be presented as a documented Scottish tradition; it is our modern creative variation.
Comparison: bourbon, rye and Scotch
| Version | Whisky | Lemon | Sweetener | Dry red wine | Typical effect | Choose it if… | |---|---|---:|---:|---:|---|---| | Bourbon classic (IBA base) | 60 ml bourbon | 30 ml | 22.5 ml 1:1 simple syrup | 15 ml | Round vanilla and caramel notes soften the sharp lemon; dark fruit sits over a sweeter-feeling base. | You want an easy introduction with a fuller, mellow profile. | | Rye classic (IBA base) | 60 ml rye whiskey | 30 ml | 22.5 ml 1:1 simple syrup | 15 ml | Rye's characteristic peppery/dry impression gives the wine's tannin more contrast. | You prefer a brisker, spice-led sour. | | Whisky Clan Scotch & honey twist (creative, not a historic regional recipe) | 50 ml unpeated blended Scotch | 25 ml | 15 ml 1:1 honey syrup | 15 ml | A lighter honeyed grain/malt character, with a softly floral sweetness and less forceful lemon. | You want to explore Scotch without allowing smoke to dominate the wine. |
Each row makes one drink. The IBA classic permits bourbon or rye; the Scotch version and its adjusted proportions are Whisky Clan's own interpretation. All three contain alcohol and may contain wine sulphites. The foaming option is omitted from the comparison because it is optional for every version.
Recipe 1: Bourbon New York Sour
One serving | Preparation: about five minutes | Style: recognised New York Sour base
Ingredients: 60 ml bourbon; 30 ml freshly squeezed lemon juice; 22.5 ml 1:1 simple syrup; 15 ml dry red wine (try a dry Shiraz/Syrah or Malbec); optional a few drops of pasteurised egg white or approximately 15 ml aquafaba for more foam; one orange or lemon zest twist; fresh ice.
Chill a rocks glass and have a fresh large ice cube waiting. Measure everything before you begin; keep the wine separate.
Pour bourbon, lemon and simple syrup into a shaker. If using pasteurised egg white or aquafaba, shake without ice first for about 10 seconds, then add ice. Without foamer, proceed straight to the ice shake.
Shake firmly with ice for 10–15 seconds until the tin is cold. Strain into the prepared glass over fresh ice, fine-straining if you want a smoother-looking surface.
Rest the spoon's back close to the drink's surface and pour the 15 ml wine slowly across it. The aim is a floating burgundy cap, not a fast pour into the centre.
Express lemon or orange oils gently over the top and add the twist. Serve immediately, unstirred, for the visual contrast.
In the glass: bourbon's sweet corn and oak-associated notes can make the sour seem softer than the rye version, though actual sweetness depends on the bottling. Choose a dry, rather than sweet, red wine so the float doesn't become syrupy. Optional egg/foam improves a creamy impression but can blur the sharp line between red and gold.
Recipe 2: Rye New York Sour
One serving | Preparation: about five minutes | Style: equally valid IBA whisky choice
Ingredients: 60 ml rye whiskey; 30 ml fresh lemon juice; 22.5 ml 1:1 simple syrup; 15 ml dry red wine; fresh ice; lemon zest. Optional 1 dash aromatic bitters is a Whisky Clan seasoning choice, not part of the IBA New York Sour specification.
Place the rye, lemon and simple syrup in a cocktail shaker. Add bitters now only if you want an extra spice layer.
Fill with hard ice and shake vigorously for 10–15 seconds.
Strain over a large fresh cube into a chilled rocks glass. Keep the glass still.
Float 15 ml dry wine over an inverted bar spoon, working slowly from one edge. Finish with an expressed lemon twist.
Taste a little of the wine-topped surface, then let the drink integrate as you sip. Avoid immediately mixing away the float if you want to experience the contrast.
In the glass: a rye-forward bottling can taste firmer and more herbal/peppery, which balances the tannic wine. If the sour feels too angular, add 5 ml simple syrup to your next preparation rather than pouring unmeasured sugar into the finished glass.
Recipe 3: Whisky Clan Scotch and honey twist
One serving | Preparation: about five minutes | This is an original Whisky Clan variation, not a documented Scottish classic
Ingredients: 50 ml unpeated or lightly peated blended Scotch; 25 ml fresh lemon juice; 15 ml 1:1 honey syrup; 15 ml dry red wine; ice; a strip of lemon peel. Optional: replace 5 ml of the blended Scotch with 5 ml of a peated Islay whisky for a faint smoky accent. This is a sensory experiment, not a claim about how people in Scotland customarily serve this cocktail.
Make a small amount of honey syrup by dissolving equal parts honey and warm water; allow it to cool. Use a runny honey with a taste you like.
Put the blended Scotch, lemon and honey syrup in a shaker with ice. Shake for 10–15 seconds and strain into a rocks glass over a fresh large cube.
Hold the back of a spoon just at the surface and trickle the 15 ml red wine onto it. Stop immediately once the float spreads.
Squeeze the oils from a piece of lemon peel above the glass, then garnish. If adding the small smoky Islay component, keep the total Scotch at 50 ml.
In the glass: delicate malt/grain, honey and lemon can be pleasantly aromatic beneath a dry-red float. Very smoky whisky may compete with wine tannin and citrus, so start with a small proportion. Don't call it a traditional New York Sour formula: the recipe and balance are deliberately different.
How to float red wine cleanly
The float matters more than a fancy garnish. Chill the base, keep the wine separate and pour slowly. A spoon held too far above the liquid lets the wine fall through and mix; a spoon near the top allows it to spread. A medium-bodied dry red that you would happily drink by itself is a sensible starting choice; a very sweet wine pushes the cocktail towards dessert, while a very tannic wine can make it taste drying.
Four quick adjustments: if the colour disperses immediately, shake/strain onto fresh ice and lower the spoon next time; if the red top is patchy, pour a consistent thin stream rather than splashes; if the drink is too sour, adjust next round's syrup by 5 ml; if the wine dominates, measure just 10–15 ml and avoid free-pouring. The soft foam created by pasteurised egg or aquafaba can affect the layering: for a high-contrast photo-style appearance, omit it.
Swap guide: Irish whiskey, sweetness, bitters and foam
Irish whiskey: for a gentle, approachable Whisky Clan variation, use 60 ml blended Irish whiskey, 30 ml lemon, 22.5 ml 1:1 simple syrup and 15 ml dry red wine. Prepare by the same method as the bourbon recipe. A lighter, grain-led example may feel softer and less peppery; this is a flavour experiment, not an established national tradition. A pot-still-led bottling could behave differently from a light blend.
Sweetener: plain 1:1 simple syrup gives a neutral baseline, good for side-by-side whisky testing. Honey syrup adds floral or herbal notes, while a small amount of demerara syrup can nudge towards darker sugar flavours. Changing from 1:1 to more concentrated 2:1 syrup changes the sweetness; don't substitute the same millilitres without tasting and recalibrating.
Bitters: one dash of aromatic bitters adds a little warm spice to the rye version. Orange bitters can emphasise citrus peel. Either is an optional creative seasoning; not essential to the IBA New York Sour.
Foam: the IBA allows a little egg white, but there is no requirement to use it. If you do, choose pasteurised egg white, use hygienic equipment and note egg allergy; a no-egg version is simplest. About 15 ml aquafaba can produce a foamy alternative, though the texture and flavour are not identical. Wine may contain sulphites, and not every wine is vegan-friendly even without egg.
Other wines: claret-style dry red, Shiraz/Syrah and Malbec can all work. Port is sweeter and changes the drink significantly; if you use it, label it a personal riff rather than claiming you have made the standard New York Sour. There is no wine-free substitute that gives exactly the same aroma and flavour.
Troubleshooting and questions
Can I make it without a cocktail shaker?
A leakproof jar with a secure lid can mix an alcohol-and-citrus sour in a pinch; strain carefully through a tea strainer and avoid anything not designed to tolerate cold shaking. A proper shaker and jigger make consistency much easier. Never shake carbonated ingredients.
Is rye always better than bourbon?
No. Rye generally offers a more spice-led impression, but differences between individual whiskeys can outweigh the category label. The cleanest test is to use the same wine, ice, lemon and syrup for both, adjusting only the whiskey.
Do you need egg white for the red-wine float?
No. Egg white is optional in the official IBA formulation. It can add body and foam but may soften the contrast between the layers. For the clearest burgundy cap, make the no-egg version first.
Can I prepare a batch for guests?
Pre-measure and refrigerate the whisky, lemon and syrup for a small adult gathering, but shake each portion with fresh ice and add the wine float only at service. Keep per-person portions measured and avoid topping up glasses invisibly.
