Liqueur
High-proof liqueurs keep one to two years opened and longer. Cream and egg liqueurs, by contrast, are perishable and belong in the fridge.
Why it all depends on the type
With liqueur it all depends on the type — and that also decides the question of a date. Classic herbal, fruit or nut liqueurs above 10 percent alcohol are exempt from a best-before date under EU law and keep for a very long time. Creamy cream and egg liqueurs, by contrast, contain perishable ingredients and therefore usually carry a voluntary date.
A high-proof liqueur of about 20 to 40 percent alcohol keeps practically indefinitely unopened, and one to two years or more once opened. Over time aroma and colour can fade, and heavily sweetened liqueurs sometimes form sugar crystals — both harmless. Stored cool and dark, the liqueur stays aromatic longest.
Cream liqueur, egg liqueur and low-proof liqueurs are a different story: their milk, cream or egg content makes them perishable. They belong in the fridge after opening and should be drunk within a few months. A glance at the label and ingredients tells you which type you have — and whether a date is printed on it.
If you are unsure which type you have, go by two simple features: the alcohol content and the ingredient list. If it reads 20 percent or more and shows no dairy, it is a shelf-stable, high-proof liqueur that practically does not spoil. If the list names cream, milk, egg or coffee cream and the alcohol is lower, the liqueur belongs in the fridge after opening. Homemade liqueurs follow the same logic: pure fruit or herbal infusions with plenty of alcohol and sugar keep for a long time, while creamy or egg-based versions like classic advocaat are perishable and should be refrigerated and used up quickly. A glance at the label settles any doubt at once.
How do I spot bad liqueur?
The warning signs depend heavily on the type:
Lumps, curdled cream or a thick, oily texture show the cream liqueur is done.
A sour or fermented smell in creamy liqueurs means spoilage.
Crystals at the bottom of high-proof liqueurs are crystallised sugar, not spoilage.
Shelf life at a glance
Alcohol content and ingredients decide how long it keeps:
| State | Shelf life |
|---|---|
| High-proof liqueur, unopened | practically unlimited |
| High-proof liqueur, opened | 1–2 years and longer |
| Cream/egg liqueur, opened refrigerated | a few months |
| Sugar crystals at the bottom | harmless |
Store it right
The right storage keeps liqueur good longest:
Store by type — high-proof liqueurs cool and dark in the cupboard, cream and egg liqueurs in the fridge.
Seal tightly — protects aroma and prevents evaporation.
Refrigerate cream liqueur — opened creamy liqueurs belong in the fridge and used up quickly.
Protect from light — preserves colour and aroma, especially in fruity liqueurs.
Common myths
A few myths surround liqueur:
No — only high-proof ones. Cream and egg liqueurs are perishable and must be refrigerated.
No — that is crystallised sugar and harmless. Gently warming dissolves it.
It does, after opening — otherwise it can curdle and spoil.
Homemade liqueurs make a lovely gift — and thanks to alcohol and sugar usually keep for many months to years. The key is to use clean bottles and, for creamy or fruit-pulp versions, to keep them chilled.
