- How long does ouzo last? The answer to that question is a matter of quality, not safety, assuming proper storage conditions - when properly stored, a bottle of ouzo has an indefinite shelf life, even after it has been opened.
To maximize the shelf life of ouzo 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 ouzo is opened, the contents may begin to evaporate slowly and some flavor may be lost over time, but the ouzo will remain safe to consume if it has been stored properly.
How to tell if ouzo has gone bad? The shelf life of ouzo is indefinite, but if ouzo develops an off odor, flavor or appearance, it should be discarded for quality purposes.
