how do you keep grains fresh
As long as you keep your grains in tightly sealed containers and use them within 3-6 months, they should stay fresh! You might find our pantry organization tips helpful:
Fridge and freezer slow down the breakdown of grains. I store my flax and nuts in the freezer. As well as my whole wheat flour.

And glass jars on a pantry shelf will prevent infestation if the critters try to invade -- the outside and in. One of the hard facts of natural foods is that they bring more nature with them than you intended.
