From personal experience, rice that has been picked recently has a much better taste. I normally buy rice from the Asian market that has a harvested date on it. Often this date is within the last month. After about 6 months the rice tends to start losing its aromatic flavors.

Brown rice has a much shorter shelf life than white rice, and will go bad if kept in a humid or hot environment. If you aren't going to use rice within 1-2 years I would say maybe freeze it so it will keep the aromatic flavors longer.
