How to Make Cocktail Bitters at Home: A Basic Recipe and Flavor Guide

Bitters are concentrated infusions of bittering agents, aromatics, and spices in high-proof alcohol. A few dashes transform an old fashioned, Manhattan, or even a glass of sparkling water. Homemade bitters take about two to four weeks of steeping, and a single batch fills several small bottles. The process is straightforward: infuse, strain, combine, and rest.

What Bitters Are Made Of

Every bitters recipe has the same four components.

Ingredients for a Simple Aromatic Bitters

• 1 1/2 cups high-proof spirit (100 proof or higher; 151-proof rum or overproof vodka works well, or bourbon for depth)
• 1 tablespoon dried gentian root
• 1 tablespoon dried orange peel
• 1 teaspoon dried lemon peel
• 1 cinnamon stick, broken
• 1 teaspoon whole allspice berries
• 1/2 teaspoon whole cloves
• 1/2 teaspoon coriander seed
• 2 cardamom pods, lightly crushed
• 1 star anise
• 1/2 cup water (for the second stage)
• 2 tablespoons rich simple syrup (2 parts sugar to 1 part water), for finishing

Gentian and other bittering botanicals are sold by herb and spice suppliers. Buy them as culinary ingredients from a reputable source.

Equipment

• Two clean pint-size glass jars with tight lids
• Fine-mesh strainer
• Coffee filters or cheesecloth
• Small saucepan
• Funnel
• Small dropper bottles (1 to 2 ounce) for storage

Instructions

1. Combine the bittering and aromatics. Place gentian, peels, and all spices in a jar. Lightly crack the whole spices to release oils.
2. Cover with spirit. Pour in the spirit until the botanicals are fully submerged. Seal tightly.
3. Steep. Store in a cool, dark place for 2 to 3 weeks. Shake the jar every day or two.
4. Taste. After 2 weeks, put a drop on your tongue or dilute a few drops in a splash of soda. It should taste intensely bitter and spiced, not yet balanced.
5. Strain. Pour the infusion through a fine-mesh strainer, then through a coffee filter into a clean jar. Keep the solids (the tincture is the liquid you just strained).
6. Cook the solids. Place the strained botanicals in a saucepan with 1/2 cup water. Bring to a boil, cover, reduce to a simmer, and cook for 10 minutes. Let cool.
7. Steep the second stage. Pour the botanical water (with solids) into a clean jar, seal, and rest 3 to 7 days.
8. Strain the second stage. Filter the cooled water through a coffee filter.
9. Combine. Mix the two liquids. Add 1 to 2 tablespoons rich syrup to soften the edges, tasting as you go.
10. Rest. Let the combined bitters sit for a few days. Any sediment will settle. Filter again if cloudy.
11. Bottle. Funnel into dropper bottles and label with the date.

Flavor Blueprints

Orange Bitters

Use dried bitter orange peel or a mix of sweet and bitter orange as the main aromatic. Add coriander, cardamom, and a little caraway. Great for martinis and old fashioneds.

Coffee-Pecan Bitters

Steep toasted pecans and coarsely cracked coffee beans with a pinch of vanilla. Pair with aged rum or bourbon drinks.

Chocolate-Chili Bitters

Use cacao nibs, a dried ancho chile, and cinnamon. Strong in mezcal, tequila, and Manhattan variations.

Lavender-Lemon Bitters

Light and floral: dried lemon peel, lavender, and a little gentian. Suits gin drinks.

Cherry-Vanilla Bitters

Dried cherries, a split vanilla bean, and a touch of almond extract. Works in bourbon cocktails.

Tips

• Use dried botanicals. Dried herbs and peels avoid the water content that invites spoilage. Fresh fruit can introduce mold and diluted extraction.
• Start with small amounts of bittering agents. Gentian is powerful; use a measured quantity and adjust in later batches.
• Keep notes. Record quantities and days of steeping so you can repeat or adjust.
• Use high-proof spirit. Higher alcohol extracts more oils and resins and keeps the bitters stable.
• Do not sweeten heavily. Bitters should stay bitter. A small amount of syrup bridges flavor.
• Filter well. Fine sediment makes bitters look cloudy but doesn’t harm flavor.
• Toast whole spices lightly. A short dry toast in a pan releases aroma. Cool before infusing.

How to Use Bitters

• 2 to 3 dashes in an old fashioned or Manhattan
• A few drops in sparkling water with a citrus slice
• A dash in a whiskey sour or gin and tonic for depth
• Splash on a sugar cube for a Champagne cocktail
• Drops in cooking or baking, such as in glazes, whipped cream, or chocolate desserts

Storage

Bitters are high in alcohol, so they keep well. Stored in a cool, dark place in sealed dropper bottles, they last for years, though flavors fade slowly. If bitters turn cloudy with growth, develop an odd smell, or form mold, discard them. Label each bottle with the date and flavor.

A Brief Background

Bitters began as medicinal tinctures in earlier centuries and later became a defining ingredient in the earliest cocktails. The word cocktail itself was once defined as a mix of spirits, sugar, water, and bitters. Today, bottled aromatic, orange, and specialty bitters are widely used, and making your own lets you control the flavor.

Troubleshooting Your Batch

Gifting

Small amber dropper bottles protect bitters from light and make tidy gifts. Label each with the flavor, date, and a suggested cocktail to try it in.

FAQ

Do I need gentian?

You need a bittering agent of some kind. Gentian is common, but quassia, dandelion root, or cinchona bark are alternatives with different notes.

Can I use vodka?

Yes, but only if it is high-proof. Standard 80-proof vodka extracts less efficiently and may produce weaker, less stable bitters.

How many bottles does one batch make?

About 1 to 1 1/2 cups, enough for several 2-ounce bottles.

Are bitters alcoholic?

Yes. They contain high-proof alcohol, but are used in drops or dashes. Treat them as an alcohol product and keep them out of reach of children.
