Tempo SC Ultra does not have an expiration date from the manufacturer, but most liquid concentrates usually have a shelf life of 5 years. You should try to use it within this time frame because the concentrates do settle over time. You should always keep the lid on tight and not place the bottle in direct sunlight. Also, you should agitate the bottle every couple of months if you are not using it to prevent the concentrate from settling.
