Canned goods should be able to last a year or more, depending on how they're stored.

( between the two of them, they've got it covered. Matt couldn't tell you how long rice keeps, but he can tell you that the dinged up close to expired canned goods his dad used to buy were still more or less edible, even a year after purchasing. )

Two months is a good start. If the need seems to lessen, we can reevaluate then.
