Cocktail Bitters Guide

Bitters are concentrated infusions of bark, roots, peels and spices in strong alcohol. A drink uses only a few drops, yet removing them leaves an Old Fashioned or Manhattan tasting flat and overly sweet. They work like salt and pepper: they sharpen edges, connect flavors and keep sugar from taking over.

You do not need a shelf of twenty bottles. This guide explains the core styles, which ones to buy first, how much a dash actually holds, how to swap one style for another, and why bitters still matter for anyone avoiding alcohol.

The core styles

Most cocktail recipes call for one of a handful of bitters styles. Each brand varies, but the families are easy to tell apart by taste.

• Aromatic: dark, spiced and woody, with clove, cinnamon and gentian; the default in Old Fashioneds and Manhattans
• Orange: bright peel with a dry, bitter finish; classic in Martinis and many gin drinks
• Peychaud's-style: red, lighter and floral with anise and cherry notes; essential in the Sazerac
• Specialty: celery, grapefruit, chocolate or mole, cardamom, lavender and many more for targeted accents

What bitters do in a drink

Gentian root, cinchona bark and similar ingredients add bitterness that balances sugar. Aromatic spices and peels add top notes you smell before you taste. Together they make a spirit-forward drink seem longer and more complex on the palate.

In sours and highballs, bitters act more as a garnish. A few drops on the foam of a Pisco Sour or Whiskey Sour add aroma to every sip and help cover the faint eggy smell of the white.

How much is a dash

A dash is whatever comes out with one sharp flick of the bottle, which depends on the size of the opening and how full the bottle is. On most standard bitters bottles it lands around 0.6 to 1 ml. A drop from a dropper bottle is much smaller, about 0.05 ml.

For consistent drinks, decant your most-used bitters into a metal-topped dasher bottle or a dropper and count. If you scale a recipe for a batch, convert dashes to milliliters first so a large quantity does not end up overly bitter.

• 1 dash: about 0.6 to 1 ml
• 1 barspoon: about 5 ml, or roughly 6 to 8 dashes
• 1 drop: about 0.05 ml

Pairing bitters with spirits

Match strong, dark spirits with strong, dark bitters and lighter spirits with lighter ones. Aromatic bitters suit bourbon, rye, aged rum and brandy. Orange bitters suit gin, dry vermouth and blanco tequila. Peychaud's-style bitters complement rye and cognac and give a pink tint.

Mixing two styles in one drink is common. An Old Fashioned with two dashes of aromatic and one of orange bitters tastes rounder than either alone. In a Vieux Carré, aromatic and Peychaud's-style bitters work together against sweet vermouth and Bénédictine.

Bitters as a main ingredient

Some drinks use bitters by the measure. The Trinidad Sour calls for a full 30 ml or more of aromatic bitters, balanced with orgeat, lemon and rye. In that case the bitters supply real alcohol and a lot of spice, and the drink is far stronger in flavor than its color suggests.

Bitters and soda, a long-standing bar order for anyone skipping a cocktail, uses several dashes in a tall glass of sparkling water. It contains only a trace of alcohol, but anyone who must avoid alcohol completely should know that it is not alcohol-free.

Making, storing and substituting

Commercial bitters keep for years at room temperature because of their high alcohol. The aroma slowly weakens once a bottle is open, so buy small bottles of specialty flavors you use rarely. You can make your own bitters by infusing botanicals in high-proof spirit and blending them, which lets you tune the balance.

When you lack a specific bitters, substitute within a family first: one aromatic for another, or orange bitters plus a strip of orange peel for a missing citrus bitters. Swapping aromatic for Peychaud's-style in a Sazerac works but gives a darker, spicier drink.

Common questions

Do bitters go bad?

They rarely spoil because of their alcohol content. Over time, especially in a warm, sunny spot, they lose aroma and can darken. If a bottle smells weak or musty, replace it.

Are bitters safe for someone who does not drink alcohol?

Bitters contain alcohol, typically 35 to 45 percent by volume. A few dashes in a large drink add only a small amount, but for anyone avoiding alcohol entirely, look for glycerin-based alcohol-free bitters or leave them out.

Which bitters should I buy first?

An aromatic bitters covers the widest range of classic drinks. Add an orange bitters next for gin and vermouth drinks, then a Peychaud's-style bottle if you enjoy the Sazerac.
