If I open a bottle of cognac, how long will it keep?

As a gift, my parents got a bottle of Remy Martin VSOP Champagne Cognac.





I'd like to try some, but it's still unopened. Some drinks start to go bad once you open the bottle and have a limited shelf life after that. If that's the case with the cognac then I'm not going to open it because I'm probably not going to drink much and a lot of it would probably go bad.|||Opening a bottle of booze won't hurt it. It has either a cap or a cork with it, just replace the top when you're done. Also, Remy Martin VSOP is less than $40 per bottle, so it isn't that big of a deal. If you were talking Remy Martin Louis XIII, that's a $1500+ bottle...you should be sure to take good care of it.|||Remy VSOP will be fine once it is opened for up to 3-4 years. You will notice some evaporation over this time but the taste will stay the same. After about year 2 you will start to notice that the flavors are starting to be come less sharp or crisp but it will still be fine to drink. As long as there is still some in the bottle it will be safe to drink but over time the taste will just become blander





hope this helps|||All Cognacs are brandys or fortified wines, basically double distilled white wine. They are about 80 proof and no longer carry the substances which can make a wine go bad. It should last quite awhile after you open it. FYi VSOP is very superior old pale, a designation that indicates that the youngest part of the blend is at least 4 years in oak.|||It shouldn't go bad anytime soon, but please, please, PLEASE make sure that they're cool with you opening it. It's really expensive and it's probably unopened for a reason.|||Cognac is fine to open. I shouldnt go bad. my dad had a bottle of hennessy for a few years opened an in the closet. It was very good.
