Unopened Grand Marnier can last indefinitely due to its high alcohol content and sugar, which act as preservatives. Once opened, it can maintain its best quality for about 3 to 5 years if stored in a cool, dark place. However, it may still be safe to consume beyond that time, although the flavor may begin to degrade. Always check for any off smells or changes in taste before using.
