How long does a bottle of opened cognac last?

Answer 1

As soon as Cognac is in the bottle it stays good. You can drink it even if its hundred years old. If it's only one age of cognac and no mix (blending) its a Vintage Cognac like the Hine Vintage Collection 1948 Cognac

Answer 2

Cognac is made to last a very long time. As long as it is not stored in direct sunlight, stored upright, and the seal is good, it can keep for centuries (I have handled 1811 Cognac that was still good). Plus, it can improve over time.

Answer 3

Generally speaking wines and spirits can be kept longer than beer usually because of the alcohol content. However, some spirits or wines can be kept longer because of the whole idea that the longer you have it, it may taste better, and some do support that trend.

Answer 4

If properly stored, it should last indefinitely.

Answer 5

The high alcohol content renders it virtually indestructible.

Answer 6

no
