- The answer to the question ? How long does gin last? is a matter of quality, not safety, assuming proper storage conditions - when properly stored, a bottle of gin has an indefinite shelf life, even after it has been opened.
To maximize the shelf life of gin for quality purposes, store in a cool dry area away from direct heat or sunlight; keep tightly closed when not in use.
Once a bottle of gin is opened, the contents may begin to evaporate slowly and some flavor may be lost over time, but the gin will remain safe to consume if it has been stored properly.
How to tell if gin has gone bad? The shelf life of gin is indefinite, but if gin develops an off odor, flavor or appearance, it should be discarded for quality purposes.
