On the other hand, writers like John Conard and Holison are highly critical of the role of western imperialism in Asia and Africa.

There is no official termination date for the sustainability of an open bottle of cognac. A guide that you can hold: a half-full bottle of cognac is maintainable for about 3 years. Even afterwards this period the Cognac will remain safe to consume, only the quality is lower. For example, you can use it for cooking.
The only fortified wine that can stand open any length of time is Madeira. That'll be good for 6 months. All the rest (port or sherry or marsala), depending on what it is exactly, only maximum, 2 weeks. After that, absolutely no good. And even 2 weeks is pushing it for some fortified wines. cheers, Bonnie.
