Report Abuse. 1  Luck for you non dairy creamer has a very long shelf life as long as you keep it refrigerated. 2  Generally it is recommended that liquid non-dairy creamers be consumed within 14 days of opening the product. 3  Non dairy creamer takes a while to go bad, but it does have an expiration date.
My two cents on milk freshness, yogurt, cheese, and the naturally long shelf life of cultured dairy products: If you get the milk the day it is milked, it will stay fresh up to 2 weeks. If it sours, no worries, it will become yogurt with no help at all (with a little sour cream on top). Without a starter, the sour cream on top usually bitters, so you can just scrape it off and compost it if you donât like the taste.
