The small green gram behind bean sprouts and dal. Vacuum-sealed it is the longest-keeping thing in this entire table at ten years.

How long it keeps

Unopened, this keeps 10 years — which is what puts it on the long shelf.

Counted from the date on the package. Figures are the USDA FSIS FoodKeeper table's, for unopened storage at room temperature; FoodKeeper counts a month as 30 days.

FoodKeeper's own note: Keep the beans in an airtight container as it’s imperative that they remain dry.

The table was not pulled from USDA — fsis.usda.gov answers 403 to non-browser clients from this machine — so it came from a mirror of the data.gov dataset and its vintage is unverified. Treat a single figure as indicative, not as a use-by date.
