Whether it's a staple part of your diet or you eat it as a side dish every once in a while, rice is a common item found in many home pantries. Consumed by more than half of the world's population daily, there are many varieties of rice commercially available. The most common in the U.S. is long-grain white rice and brown rice. While brown rice has a much shorter shelf life than white rice, both need to be stored in the same way. Freezing rice is the best way to preserve the grain for as long as possible.
Place loose rice in large, zipped-top freezer bags. If you have a small box of rice, you can place the whole box in a large freezer bag and place in the freezer as is.
Place the freezer bags in large, plastic, airtight containers. Label which ones contain white rice and which ones contain brown rice.
Place the containers in the freezer. Brown rice will last in the freezer anywhere from 12 to 18 months. White rice stored in the freezer can remain good to eat indefinitely.
