Shelf life of liqueur: What you need to know

Liqueur is a popular drink that is perfect for cocktails, culinary experiments or simply to enjoy. But what about its shelf life? In this blog post, you will learn everything you need to know about the shelf life of liqueur, whether bought or homemade.

Shelf life of store-bought liqueur

Alcohol content as a preservative: One of the main factors that influence the shelf life of liqueur is the alcohol content. Alcohol acts as a natural preservative that inhibits the growth of microorganisms. Liqueurs with a high alcohol content (over 30%) generally have a longer shelf life.

Sugar and additional ingredients

Additional ingredients such as sugar, herbs or fruit can also affect the shelf life. Sugar also acts as a preservative, but some additives can shorten the shelf life.

Storage and packaging

The type of storage plays a decisive role. Liqueur should be stored in a cool, dark place and ideally upright. Once opened, the bottle should be tightly closed and consumed within a year.

Shelf life of homemade liqueur

Homemade liqueur has its own peculiarities in terms of shelf life. Here are some tips:

Sterile working conditions

Ensure clean and sterile working conditions to extend the shelf life of your liqueur. This also includes the use of sterilized bottles and equipment.

Use fresh ingredients

Using fresh, high-quality ingredients is not only crucial for taste, but also for shelf life.

Monitoring and filtration

Make sure to check the liqueur regularly and remove any cloudy substances by filtration. This helps to extend the shelf life.

Note the alcohol content

As with commercial liqueurs, the alcohol content is decisive for the shelf life. A higher alcohol content helps to extend the shelf life of the liqueur.

Expiration date and loss of quality

While liqueur does not necessarily go "bad", it can lose quality after a certain amount of time. Flavors can change or become flat. It is therefore advisable to consume the liqueur within a certain period of time to get the best taste experience.


The shelf life of liqueur depends on various factors such as alcohol content, additional ingredients and storage conditions. With the right knowledge and a few precautions, you can ensure that your liqueur lasts as long as possible and retains its full flavor.
