How to Make a Liquor Infusion

Choose one spirit and one primary flavor before adding anything else. A neutral vodka makes delicate ingredients easy to read; gin, rum, tequila, and whiskey bring their own character, so choose additions that have room beside it.

Use clean jars and sound, food-safe ingredients. Remove any bruised or spoiled pieces, and keep water-heavy ingredients fully below the spirit while they steep. This is kitchen technique, not a preservation project: make manageable amounts and use good judgment about freshness.

For a 750 mL bottle, begin with enough fruit, herb, spice, coffee, or tea to make the spirit visibly aromatic without crowding the jar. Think a generous handful of sliced fruit, a small bundle of herbs, a few whole spices, or a modest scoop of coffee beans—not a fixed formula.

The right ratio is the one that tastes balanced in a finished drink. Strong ingredients such as chile, vanilla, fresh ginger, and bitter citrus peel need a lighter hand than strawberries or cucumber.

Pour the spirit over the ingredient, seal it, and keep it away from heat and direct light. Taste a small spoonful periodically, beginning earlier with herbs and spices than with fruit. The moment the added flavor is distinct but still leaves room for the base spirit, strain it.

Fine-strain through a clean fine-mesh strainer or coffee filter if you want a tidier bottle. Filtering slowly is better than squeezing aggressively, which can push bitter pulp and sediment through the filter.

Try the infusion first in a familiar build: replace half the base spirit in a Martini, Sour, Highball, or Old Fashioned. That gives you a clear read on what the infusion brings before you build a more elaborate recipe around it.

Date and label the bottle, store it tightly closed in a cool, dark place, and inspect it before serving. Flavor changes over time, especially with fresh ingredients, so small batches are more useful than a forgotten large one.
