I have about 20 packs dated 2007 and 2008. It's the kind you add sugar to, and the packets have been stored in the pantry and look and sound fresh. I know I can make it and drink it to see if we live but I was curious. Is this one of those items that really doesn't need an expiry date, but is there just for those who want it? Citric acid is the first ingredient lsited. Oh, wow, I just saw that it's made in Mexico too. So much for Kool-Aid being American.
