Red Wine
The bar asks different questions of a red than the table does. A float or a punch needs colour, dry fruit and enough tannin to stay audible next to lemon and spirit, which is not the same thing as a good bottle.

Tasting Notes
Blackberry and plum fruit over drying tannin: the qualities that read loudest against citrus and whiskey.
Storage & Handling
Open bottles keep two to three days re-corked in the fridge: bar use is more forgiving than the glass.
Shelf Life
Open: 2 to 3 days refrigerated for cocktail duty
Usage
Cocktails use red wine as a modifier: the New York Sour’s crimson float, mulled winter serves, sangria and punch. Choose dry, fruity and emphatic, and treat fine bottles as drinks in their own right rather than ingredients.
What the Bar Asks of a Red
Wine and the cocktail have been colleagues since the punch bowl, and the bar asks different questions of a red than the table does: not complexity or finesse, but colour, fruit and enough tannin to stay audible next to lemon and spirit. A 15ml float has no room for subtlety.
That rules out most of what makes an expensive bottle expensive. Age, restraint and a long finish are all invisible under citrus, and an oaky red simply arrives as wood.
The New York Sour
The New York Sour is the modern showcase, a stratum of dry red floated over a rye sour so the drink descends from wine to whiskey through a blended middle. Syrah and malbec float best: dark-fruited, structured and unbothered by the citrus below.
The drink is usually drunk without stirring, so the first mouthful is wine, the last is sour, and the middle is the point of the exercise.
Why the Float Floats
It is density rather than technique. A sour carries sugar dissolved in it, and sugar makes the liquid heavier than dry wine, so the wine will sit on top if it is given the chance to settle rather than being dropped in. Pouring slowly over the back of a barspoon held just above the surface spreads the wine sideways instead of down.
It follows that a sour built dry, with little or no sugar, gives the float nothing to sit on and the wine sinks. If a float keeps failing, the problem is usually the drink underneath it rather than the pour.
Beyond the Float
Red wine anchors sangria and mulled serves and lends punches their depth, and in every role the same rule holds: buy honest, fruit-forward and dry. Last night’s open bottle is the traditional source and a perfectly good one, since two or three days of air matters far less here than it would in a glass.
What does not work is the reverse economy of opening something serious for the purpose. A bottle worth thinking about is worth drinking on its own terms.
Top Tips
- Syrah and malbec are the bartender’s reds: dark fruit and enough tannin to survive lemon juice.
- Last night’s open bottle is the traditional and correct source for a float.
- Never float an oaky or delicate red: subtlety drowns in a sour.
Possible Substitutions
- Port, in half measure: sweeter and heavier, for richer floats
- A splash of creme de cassis plus dry red: deepens a thin wine for float duty
Production Method
Fermented on the grape skins, which contribute the colour and tannin that let a red read through citrus and spirit where whites disappear.
Common Questions
What red wine goes in a New York Sour?
Dry and fruit-forward with some tannin: syrah and malbec are the standard calls, because both are dark enough to show as a distinct layer and structured enough to survive the citrus underneath. Presence matters more than pedigree, and last night’s open bottle is the traditional source.
Does the wine need to be good?
It needs to be sound, dry and emphatic, which is not the same as good. Fine wine is wasted in a 15ml float, where age and restraint are invisible under lemon, and a delicate red disappears entirely. An oaky one arrives as wood rather than as fruit.
How long does an open bottle keep for cocktails?
Two or three days re-corked in the fridge: float and punch duty is far more forgiving than drinking it from a glass. Oxidised, vinegary wine is past service in either role.
How do you float red wine on a sour?
Pour it slowly over the back of a barspoon held just above the surface, so it spreads sideways rather than dropping through. It floats because the sweetened sour beneath is the denser liquid, so a sour built too dry gives the wine nothing to sit on.
