To be honest, if you buy any variety of our Tiger Nuts in Kilo boxes and don't open them, they'll keep indefinitely in a cool area until you open the shrink wrap, and even then, you'll have a year.
All our Tiger Nuts products are expiry code dated and can be found on our website www.tigernutsusa.com, Amazon, WalMart, and Kroger, as well as our retail partners like Natural Grocers, where we sell from coast to coast. This date is normally one year after it leaves our Organic certified facilities.
Hope this helps!
