Expiration & Storage Tips
When does hazelnut liqueur expire?
An unopened bottle of hazelnut liqueur can last indefinitely if stored properly, even after the 'best by' date on the bottle as this is more directed towards optimal flavor, not safety. However, once opened, it would ideally be consumed within six months, but can safely last up to a year or potentially even two. Keep in mind that the flavor may start to decline after the six-month mark. Freezing is not commonly used for liqueur, but can be done. Thawing should naturally occur at room temperature.
How do you tell if hazelnut liqueur is bad?
Signs of spoilage in hazelnut liqueur can include a distinct change in smell - a sour or off smell is a sure sign that something's wrong. Unwanted flavor changes or any signs of mold growth are also indications that the liqueur has spoiled. Additionally, if the liqueur has been exposed to high temperatures or direct sunlight causing it to look cloudy or discolored, it's best to toss it out.
Tips for storing hazelnut liqueur to extend shelf life
• Store unopened bottles in a cool, dark place like a pantry or cabinet.
• Once opened, seal the bottle tightly and keep it in a cool place, but it doesn't necessitate refrigeration.
• Don't expose the liqueur to extreme temperature fluctuations as it can affect its quality and taste.
• To ensure freshness, try to consume within six months of opening, although it can last much longer.
