Have you ever wondered how long you can keep that expensive bottle of wine without it spoiling? Or have you ever wanted a single shot but you were too scared to open the bottle and risk wasting the rest. It is true some liquors keep longer than others and shelf lives differ across products because of different sugar contents and oxidation resistances.
 

Liqueurs and flavoured liquors have a higher sugar content and generally higher concentrations of alcohol than other alcohols. Some liqueurs can remain fresh whether unopened or opened for up to two years. Most liqueurs have a label stating their expiry date for your convenience.
 

Liquors are distilled alcohols without the flavourings or added sugars that liqueurs have. They have high alcohol contents and are generally unresponsive to oxidation. Liquors have a much longer shelf life. These liquors should be stored in a cool, dry environment with low light to extend their shelf life and they can keep indefinitely.
 

Wine has the shortest shelf life of them all. After wine has been exposed to the air, oxygen seeps into the liquid and alters its composition. An open bottle of wine will only keep fresh for about 3 days without losing its flavour.
