After opening, Kahlua does not need to be refrigerated, but it should be kept in a cold, dark location, such as a pantry. After opening, the shelf life of Kahlua is between three and four years.

Kahlua is a liqueur made from rum, arabica coffee, sugarcane spirit, vanilla, and caramel. Due to its 20 percent alcohol concentration, it can be stored in a pantry as opposed to a refrigerator. Typically, the alcohol content must be greater than 17 percent for the liqueur to be non-refrigerable.

To properly store Kahlua, secure the cap completely and keep it away from excessive temperature changes and harsh lights. The best places to store booze are in pantries, cabinets, and cool basements. In addition to wiping the bottle mouth and neck after each use, it is essential to clean around the cap, as a small quantity of liquid can attract fruit flies or make the lid difficult to open.

According to Kahlua.com, Kahlua has a shelf life of around three to four years after original opening. Even if the liqueur lasts longer, it may lose its unique flavour, necessitating its discard and replacement, particularly if it was not stored properly.
