The best-before date (BBD or DLC in French) indicates that the product can be used at its optimum quality up to the date indicated. After this date, the product may have lost its flavour and organoleptic qualities, and its colour may change.
Until 2019, all e-liquids had a stated best-before date (gradually being replaced by a shelf life date). You can therefore use an e-liquid with an expired shelf life date, but its flavours will not be optimal, and it will not necessarily have the same color. Calumette recommends that you do not use an e-liquid with an shelf life date that is too far out of date.
