Bitters are the smallest thing on most cocktail recipes and the most important. A few dashes can take a drink from "fine" to "balanced" or from "balanced" to "the version you remember a week later." If you've ever wondered why we keep four or five small dark bottles on the side of the station, this is what they're for.
What bitters actually are
Bitters are concentrated alcoholic infusions of bittering agents . barks, roots, seeds, peels . usually with a base of high-proof neutral spirit. They were originally sold as medicines in the 1800s, marketed as cures for everything from indigestion to malaria. The "cocktail" itself, in its earliest 1806 definition, was specifically "a spirituous liquor of any kind, sugar, water, and bitters." Bitters were a required ingredient. They're the reason cocktails are called cocktails.
Modern bitters are still made the same way: alcohol, bitter botanicals, time. A dropper-bottle worth has very little alcoholic effect on a drink. Two or three dashes adds maybe half a millilitre. What they're doing is providing aromatic and bitter complexity that you can't easily get any other way.
Angostura aromatic bitters
The one you've definitely seen. The original Angostura, with the oversized paper label that doesn't fit the bottle (the story is they ordered the wrong size and the labels stuck), has been made in Trinidad since 1824. Originally formulated by a German doctor in Venezuela as a stomach remedy. It crossed into cocktails almost immediately and never left.
Taste: clove, cinnamon, allspice, a dry bitter finish. Smell: Christmas. If you've ever drunk an Old Fashioned, a Manhattan, a Pisco Sour, a Champagne Cocktail, or pretty much any classic with the word "bitters" unspecified in the recipe, you've had Angostura.
Use case: this is the default. Two or three dashes pulls a drink together and adds a baking-spice backdrop. Most bartenders, ourselves included, will reach for Angostura first if they're improvising.
Peychaud's bitters
The one that goes in a Sazerac. Created in 1830 by Antoine Amédée Peychaud, a Haitian-Creole apothecary in New Orleans. The Sazerac, the official cocktail of New Orleans, is built on Peychaud's; the Vieux Carré is too.
Taste: anise, gentian, a brighter and slightly floral profile than Angostura. The colour is noticeably red. The texture is thinner.
Use case: when you want bitter complexity but without Angostura's heavy spice. Lovely in stirred rye drinks. Surprisingly good with rum.
Orange bitters
The one that's standard but easy to forget. Orange bitters were popular in the late 1800s and early 1900s, then almost disappeared during the cocktail dark age (mid-century), then came back with the revival. Multiple brands make them now, all slightly different. The most-used in modern bars are Regan's, Angostura Orange, and Fee Brothers West Indian.
Taste: dried orange peel, cardamom or coriander notes depending on the brand, light bitter finish. Smell: somewhere between marmalade and old-fashioned hard candy.
Use case: any time you want to lift a stirred drink and add a citrus top note without adding actual citrus juice. A Martini with a dash of orange bitters is a different drink to one without. Negroni variants benefit from a dash.
Chocolate bitters
Cocoa, cacao nibs, sometimes coffee. Very small but identifiable, especially in dark-spirit drinks. We use a dash in a richer Old Fashioned to ground the sweetness. Also lovely with mezcal.
Aromatic bitters (the umbrella)
This is a loose category for bitters that lean into spice and bark without being specifically orange-led or chocolate-led. Several modern brands (Bittermens, Bittercube, House Bitters) produce house aromatics that sit somewhere between Angostura and Peychaud's in profile. Useful to have one alternative aromatic on the shelf for variation.
The modern, ingredient-specific range
Since the early 2000s cocktail revival, bitters makers have gone wild. There's now a bitters for almost any flavour you can think of. The ones we actually reach for:
- Celery bitters: dry, savoury, perfect with gin. We've used them in a Garden Stirred variant.
- Cardamom bitters: warm, almost dessert-like. Excellent with whisky.
- Black walnut bitters: deeper than Angostura, woody. Old Fashioned territory.
- Mole bitters (Bittermens): chilli, cacao, spice. Built for mezcal. Magic in an Oaxaca Old Fashioned.
- Lavender bitters: floral and dry. Tricky; easy to overdo. We use one drop, never more.
- Hellfire / habanero bitters: capsaicin in a bottle. Two drops total in a margarita gives a long, slow heat. More than that is dangerous.
Local possibilities
One area we've been exploring: bitters made from Malaysian botanicals. Pandan-based bitters work. Lemongrass too. Tamarind for sourness. There are small-batch Malaysian bitters makers operating in KL and Singapore now; we use a few of them rotationally. If you're a maker working on local bitters and want to send us samples, ask at the bar.
How to think about dosing
A "dash" of bitters is the amount that comes out of the bottle with a brisk single shake . about a quarter of a millilitre, give or take. For most stirred classics, two to three dashes is right. For more concentrated bitters (chocolate, mole, hellfire), one dash. For light stuff like floral bitters, sometimes just a drop from a dropper.
The most common bitters mistake we see at home is too few dashes. People are scared of overdoing it. The reverse is usually the problem: the drink reads under-seasoned and the maker can't tell why.
If you only buy one bottle
Angostura. It's available in every supermarket, it's the default in almost every classic recipe, and it'll last you years of home drinking before you finish the bottle. If you buy two, add Peychaud's. If three, add a good orange bitters. From there, the modern bitters world opens up however you want.
One small note on storage
Bitters keep almost forever because of the high alcohol base. A bottle in a kitchen cupboard at room temperature stays good for years. Refrigeration isn't needed. Light is the only real enemy; keep them out of direct sun.
Bitters are one of the cheapest ways to add genuine complexity to a drink at home. Two or three dashes in a glass with whisky, sugar, and an ice cube gets you something far more interesting than the same drink without them.
Frequently asked questions
What are cocktail bitters?
Bitters are concentrated alcoholic infusions of bittering agents like barks, roots, seeds, and citrus peels, with a high-proof neutral spirit base. They were originally sold as medicines in the 1800s and crossed into cocktails by the 1806 definition that named the category. A few dashes adds aromatic and bitter complexity you cannot easily get any other way.
How many dashes of bitters should I use?
A dash is the amount that comes from a brisk single shake of the bottle, around a quarter of a millilitre. For most stirred classics (Old Fashioned, Manhattan) two to three dashes is right. For concentrated bitters like chocolate, mole, or hellfire, one dash. For floral bitters like lavender, sometimes just a single drop. The most common home mistake is too few dashes.
What's the difference between Angostura and Peychaud's bitters?
Angostura (Trinidad, 1824) tastes of clove, cinnamon, and allspice with a dry bitter finish and noticeable colour. Peychaud's (New Orleans, 1830) is anise-forward, brighter, more floral, lighter in body, and visibly red. Angostura is the default for an Old Fashioned or Manhattan; Peychaud's defines the Sazerac and Vieux Carre. Most serious bars keep both behind the station.
Can I substitute one bitter for another?
Sometimes, with caveats. Swapping Peychaud's for Angostura in a Manhattan gives a brighter, less spicy drink that is good but different. Orange bitters often supplement rather than replace aromatic bitters. Avoid swapping intense bitters (mole, hellfire) for mild ones; the drink changes too much. If a recipe specifies a brand, the brand was chosen for a reason.
Which bitters should I buy first?
Angostura. Available in every Malaysian supermarket, it is the default in almost every classic recipe and will last years of home drinking before you finish the bottle. If you buy two, add Peychaud's. If three, add a good orange bitters (Regan's, Angostura Orange, or Fee Brothers West Indian). From there, the modern bitters world opens up however you want.
