How long will my wheat store?
Some of my wheat I vacuum sealed in bags and some I vacuumed into preserving jars using a Food Saver. I placed the bags and jars into food grade buckets (not vacuum sealed) to protect them and stored them in the basement of our home which keeps an average temperature of 10-12 deg. C year round. I live in NZ.
If kept free of outside moister and vermin wheat in whole grain form will store for 30 years or more. Wheat seed was found in the pyramids that was dated to around 2500 BC or 4,500 years old – scientists planted some of the seed and it sprouted and grew.
A good food storage shelf-life chart that I think you will find useful can be found here.
