How long do homemade liqueurs last?

Expanded Explanation

Homemade liqueurs can last for many months and often much longer if they are made and stored properly. A well-balanced liqueur with enough alcohol, clean equipment, good filtration, and a tight bottle closure is usually quite stable. Many fruit, spice, nut, and coffee liqueurs continue tasting good for a long time when kept away from heat and light.

The exact shelf life depends on the final alcohol strength, the type of ingredients used, and whether solids were removed properly after infusion. Liqueurs made with fresh fruit pulp, herbs left in the bottle, or lower alcohol content are generally less stable than well-filtered liqueurs bottled at a stronger ABV.

Storage conditions matter as much as the recipe. Keep homemade liqueurs in sealed bottles in a cool, dark place. If the aroma turns sour, rotten, moldy, or obviously wrong, the batch should be discarded. In most cases, though, properly made homemade liqueurs last surprisingly well and often improve after a short resting period.
