Store that rice and other dry stuff in the deep freeze if you have room. It will last a long time.
Storing any grain product in the freezer is a good idea simply because it's not uncommon for grains to harbor insect eggs even after cleaning and processing, or which are introduced at some other point in the process.
I had a bag of sweet sushi rice that I opened one day and discovered that I was no longer alone in my kitchen.
Storing it in the freezer eventually kills those critters. And, for some grains like brown rice, cracked wheat, or whole wheat flour, which have a fair amount of fat in them, it prevents the fat from going rancid a LOT longer.
