Ingredient substitution guide

Every shelf has a gap on the night you need the bottle. A good substitution is not a compromise so much as a translation: you keep the drink's structure and change one voice in it. This guide is organized by the role an ingredient plays, because the role tells you what the replacement must do. Most swaps below come from the substitutions written into our recipe records, so a reader moving between a recipe page and this guide will find the same advice in both places.

Two habits make substitution reliable. First, change one ingredient at a time and taste before touching a second. Second, write the swap on the recipe card with the date, so the version that worked is the version you make next time.

Base spirits: stay inside the family

The base spirit carries the weight of the glass, so the safest swap stays within its family: whiskey for whiskey, rum for rum, brandy for brandy. Cross-family swaps make a different drink with its own name, and several classics began that way. Keep the volume the same and watch sweetness: bourbon reads rounder than rye, aged rum fuller than white.

Ingredient	Substitute	Ratio adjustment	What changes in the glass
Bourbon (Old Fashioned, Whiskey Sour)	Straight rye whiskey	Same 2 oz / 60 ml	Drier, spicier, closer to the nineteenth-century build
Rye whiskey (Manhattan)	Bourbon	Same volume; consider a drier vermouth or a third dash of bitters	Rounder and sweeter
Rye whiskey (Manhattan)	Blended Scotch whisky	Same 2:1 ratio	The Rob Roy, softer and often smokier
White rum (Daiquiri, Mojito)	Lightly aged rum, 1 to 3 years	Same volume	Vanilla and a fuller body, less crisp
White rum (Daiquiri)	Rhum agricole blanc	Same volume	Grassy and vegetal, closer to a Ti Punch
Cognac (Sidecar)	Armagnac, or a good Spanish or American brandy	Same 2 oz / 60 ml	Armagnac is rougher and more rustic; California brandy stays gentle
Blanco tequila (Margarita)	Mezcal, or a half-and-half split	Same 2 oz / 60 ml total	Smoke and earth; the lime and liqueur carry it
London dry gin (Martini)	Vodka	Same volume, keep vermouth and add orange bitters	Cleaner and less botanical
Gin (Negroni)	Bourbon or rye	Equal parts, or raise whiskey to 1.5 oz / 45 ml	The Boulevardier, warmer and rounder
Bourbon (Old Fashioned)	Aged rum or reposado tequila	Same volume, same sugar and bitters	Documented modern variations, molasses or agave in place of grain

Modifiers: vermouth, amaro and liqueurs

Vermouth and amaro bring sugar as well as flavor, so a swap here moves sweetness and bitterness at once. Bianco vermouth is pale like dry but sweeter than either, typically above 130 g of sugar per liter, which is why it can replace sweet vermouth in a Negroni but turns a Martini into a softer, sweeter drink. Whatever you open, keep it in the fridge and use it within about six weeks; oxidized vermouth is a common reason a Manhattan tastes flat.

Ingredient	Substitute	Ratio adjustment	What changes in the glass
Sweet vermouth (Manhattan, Negroni)	Half sweet, half dry vermouth	Same total volume	Drier and more herbal; the Perfect Manhattan
Sweet vermouth (Manhattan)	Dry vermouth	Same volume	The Dry Manhattan; lemon twist or olive
Sweet vermouth (Negroni)	Bianco vermouth	Same volume	Paler, sweeter, vanilla-led
Dry vermouth (Martini)	Blanc quinquina with a vodka split	2 oz gin, 0.66 oz vodka, 0.33 oz quinquina	The Vesper, rounder and more bitter-orange
Campari (Negroni)	Another Italian red bitter aperitivo	Same volume, adjust by taste	Lighter bitters make a gentler drink
Cointreau (Margarita, Sidecar, Singapore Sling)	Dry curacao or triple sec	Same volume; in a Margarita pull lime back to 0.75 oz / 22 ml	Lighter and more bitter-orange; sweetness varies by bottle
Cointreau (Sidecar)	Grand Marnier	Same volume; reduce lemon to 0.5 oz / 15 ml	Cognac weight and more sweetness
Benedictine (Singapore Sling)	Yellow Chartreuse or Drambuie	Same 0.25 oz / 7.5 ml	Honeyed herbal weight with a character of its own
Cherry Heering (Singapore Sling)	Another dark cherry liqueur	Same volume	Keeps color and stewed-cherry depth; kirsch makes a drier, paler sling
Part of the base spirit (any stirred drink)	Vermouth or amaro	Swap 0.25 oz / 7.5 ml at a time and taste	Lower alcohol; reduce other sweeteners to match

Sweeteners and syrups: match sweetness, not volume

A 2:1 rich syrup carries more sugar per spoon than a 1:1 simple syrup, so the two are not interchangeable at equal volume. Our house rule, and the one written into the Daiquiri record, is to use about two thirds of the volume when moving from 1:1 to 2:1: 0.75 oz (22 ml) of simple becomes 0.5 oz (15 ml) of rich. Going the other way, raise the volume by about half. Demerara syrup is most commonly made 2:1 and pairs with dark spirits. Agave nectar is used undiluted; as a house starting point, begin at two thirds of the simple syrup volume and taste.

Ingredient	Substitute	Ratio adjustment	What changes in the glass
Simple syrup 1:1 (Daiquiri)	Rich demerara syrup 2:1	0.75 oz / 22 ml becomes 0.5 oz / 15 ml	Molasses warmth, reads older and rounder
Simple syrup (Whiskey Sour)	Honey syrup 1:1 or rich demerara	0.5 oz / 15 ml for either	Honey leans toward the Gold Rush; demerara adds depth
Sugar cube (Old Fashioned)	Maple syrup	0.25 oz / 7.5 ml dark maple	Autumn sweetness, pairs with rye
Sugar cube (Old Fashioned)	Rich demerara syrup	0.25 oz / 7.5 ml	Dissolves instantly; no grains in the glass
Rich demerara syrup (Irish Coffee)	2 tsp brown sugar or 2 brown sugar cubes	Stir until fully dissolved before the cream	The older form; undissolved grains break the cream float
Cointreau (Margarita)	Agave nectar, no orange liqueur	0.5 oz / 15 ml agave	Tommy's Margarita, the purest expression of the tequila
Simple syrup (Mojito)	2 tsp superfine or demerara sugar	Muddle with the mint	Traditional Cuban build; crystals help bruise the leaves
Grenadine (Singapore Sling)	Homemade pomegranate syrup	Equal parts pomegranate juice and sugar, same volume	Tart edge returns; avoid dyed corn-syrup grenadine
Sweetened cream of coconut (Pina Colada)	Unsweetened coconut cream plus rich syrup	1 oz / 30 ml coconut cream and 0.5 oz / 15 ml 2:1 syrup	You control the sugar; texture slightly thinner

Citrus and acids

Lime and lemon are close in acidity and can trade places in an emergency, though lime is greener and lemon brighter, and the drink will read as a cousin rather than a twin. The softer route, used in several of our records, is to replace half the citrus with fresh orange or grapefruit juice while keeping the total volume the same and pulling the syrup back slightly, since orange and grapefruit carry their own sugar. Bottled juice is not a substitute for fresh; if the bar has no fruit, the better swap is a different drink.

Ingredient	Substitute	Ratio adjustment	What changes in the glass
Lemon juice (Whiskey Sour, Sidecar)	Half lemon, half fresh orange	Keep the total at 0.75 oz / 22 ml, reduce syrup slightly	Softer, mid-century profile; brunch-friendly
Lime juice (Margarita)	Half lime, half grapefruit	Same total, pinch of salt in the shaker	Between a Margarita and a Paloma
Lime juice (Mojito)	Half a lime in wedges, muddled	Replace the measured juice	Peel oil and a Havana street build; muddle gently
Lime juice (Pina Colada)	Omit	None	Sweeter and softer, as in the Caribe Hilton original
Pineapple juice (Singapore Sling)	Omit, raise lime, top with soda	Lime to 0.75 oz / 22 ml, 2 oz / 60 ml soda	Drier and more spirit-led, closer to the 1922 Straits Sling, which had no pineapple

Bitters

Bitters are seasoning, so swaps are measured in dashes and judged by aroma. Aromatic, orange and anise-leaning bitters each pull a drink in a different direction; none of them changes volume enough to matter.

Ingredient	Substitute	Ratio adjustment	What changes in the glass
Angostura (Old Fashioned)	Half Angostura, half orange bitters	2 dashes of each	Brighter citrus; suits bourbon
Angostura (Manhattan)	Peychaud's	Same dashes	Lighter, with anise and cherry; Kappeler's 1895 recipe names Peychaud's or Angostura
Orange bitters (Martini)	Absinthe rinse in the glass	Rinse and discard	Faint anise lift in place of the orange

Egg white, cream and dairy

Egg white builds foam and softens acidity. The usual egg-free stand-in is aquafaba, the liquid from a can of chickpeas; it foams well after a dry shake, adds a little more liquid than egg white, and some drinkers notice a faint bean note. Commercial foamers such as Fee Foam (polysorbate 80 based) work in tiny doses and add almost no volume. Allergen notes: egg white is an egg allergen; aquafaba is made from chickpeas, a legume, and should be declared for guests with legume allergies; cream is dairy; FDA's January 2025 guidance no longer treats coconut as a tree nut for US allergen labeling, but cream of coconut is still worth naming for guests who avoid it. Raw egg carries a food-safety angle: use pasteurized egg white where available and keep it cold.

Ingredient	Substitute	Ratio adjustment	What changes in the glass
Egg white (Whiskey Sour)	Aquafaba	0.75 oz / 22 ml, dry shake 20 seconds	Slightly looser foam, egg-free
Egg white	Commercial foamer	Follow the label; one brand's one-ounce bottle covers 80 to 90 drinks, so the dose is a few drops	Foam without added liquid
Heavy cream, 36 percent fat or more (Irish Coffee)	Double cream (UK) or whipping cream of at least 35 percent fat	Same volume, lightly whipped	Lower-fat cream will not hold a float; aerosol cream collapses
Sweetened cream of coconut (Pina Colada)	Coconut milk	Not recommended	Too thin to stand in

Nonalcoholic stand-ins

Zero-proof spirit alternatives have improved, but the honest rule is that they replace aroma more than weight. Most nonalcoholic variations in our records add something back for body and grip: cold black tea for tannin where whiskey or cognac would have been, a little pineapple juice for weight in a Daiquiri, tart cherry juice in a Manhattan, orange juice standing in for an orange liqueur's aroma in a Margarita.

Ingredient	Substitute	Ratio adjustment	What changes in the glass
Bourbon (Old Fashioned)	Oak-aged zero-proof whiskey alternative plus cold black tea	2 oz / 60 ml alternative, 0.5 oz / 15 ml tea	Tea supplies the tannic grip
Rye and vermouth (Manhattan)	Zero-proof whiskey and vermouth alternatives plus tart cherry juice	2 oz / 60 ml, 1 oz / 30 ml, 0.25 oz / 7.5 ml	Cherry juice gives the body spirit would have
Gin, Campari, vermouth (Negroni)	Zero-proof bitter aperitivo, vermouth and gin alternatives	Equal parts, 1 oz / 30 ml each	Keeps the shape, loses weight
White rum (Daiquiri)	Zero-proof rum alternative plus pineapple juice	2 oz / 60 ml, plus 0.25 oz / 7.5 ml pineapple	Pineapple stands in for the rum's weight
Cognac (Sidecar)	Zero-proof oak-aged alternative, orange juice, orange syrup	2 oz, 0.5 oz, 0.25 oz, plus a barspoon of cold black tea	Tea adds the grip the cognac gave
Rum (Mojito, Pina Colada)	Chilled green tea or a zero-proof alternative	1 oz / 30 ml	Keeps the aroma and most of the refreshment

A closing note on naming

When a swap changes the drink enough to have its own name, use the name. A Manhattan with Scotch is a Rob Roy, a Negroni with whiskey is a Boulevardier, and a Margarita with agave in place of liqueur is a Tommy's. Naming the drink honestly is part of good service and keeps the guest's expectations where they should be.
