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