As a licensed bartender the shelf life of alcohol is indefinite. However; after a bottle is opened and shelved over a year its taste will be different. In the instance of gin and its taste after being opened and shelved for a year or more; the taste may very well be quite nasty. Gpod luck! #takeAshot #tasteitbeforethrowingitaway
I'm not sure what you should do but doesn't liquor get better with age? I hope that you find the answer.
