How long does Black bean sauce last in the fridge once opened?
Turning the range into a date
Black bean sauce keeps 3–6 months in the fridge once opened. Two clocks run on this item: one from the day it went into storage and one from the day the seal broke. Both are listed below, 2 rows in all.

Sealed against opened
Opening the package costs 4 times here: 24 months sealed in the pantry against 6 months open in the fridge. That is a real difference and worth dating the container for, but not the collapse it becomes for the more perishable items in the same list. On the same shelf it sits 13 of 41, between Cranberry sauce at 2 years and Oyster sauce at 24 months.
Every storage figure the USDA publishes for this item
The USDA gives this item a pantry and a refrigerator figure and no freezer figure at all, the pattern behind 79 of the 466 foods in the data.

- Once opened · in the fridge3 months to 6 months
Can you freeze black bean sauce?
The USDA prints no freezer time for black bean sauce. Frozen at 0 °F any food stays safe; whether it is still good after thawing is a matter of quality. Keep the fridge at 40 °F or below and the freezer at 0 °F.
How to tell if black bean sauce has gone bad
Go by the date first: black bean sauce keeps 3–6 months in the fridge once opened. A bulging, leaking or badly dented can, or a jar whose lid has popped, goes out unopened; so does mold or fizzing in an opened one.

Is it still safe to eat, or just past its best?
The answer at the top of this page reads 3 months to 6 months in the fridge once opened. Nothing here names the food: neither Black bean sauce nor the heading it sits under says whether it spoils dangerously or keeps itself. Past it, take the shorter of the two answers: we would rather print that the record does not settle it than pick one for you.
The figure in the pantry here is a quality window. The same page carries windows of more than one kind, so which sentence applies depends on which row you are reading, not on the food.
It is past the date. Now what?
Say the calculator above puts Black bean sauce past its 3 months to 6 months in the fridge once opened window. If the food is moist, low in acid and ready to eat — a sauce, a drink, a filling — treat the date as a limit and throw it out untasted; otherwise look and smell, and out it goes if either is off.
The USDA's limit for perishable food standing at room temperature is 2 hours, or 1 hour when the kitchen is above 90 °F, and that clock runs whatever the storage figure says. The whole rule, including the cases the source does not cover, is set out under what to do when the date has passed.

Where these numbers come from
Every storage time on this page is the USDA’s own published figure from the FoodKeeper data, one of the 9 it keeps per food, reproduced unchanged and never an estimate of ours. Where the USDA lists several kinds under one name, each kind keeps its own windows, and the page names the kind its answer is for. The dates and multipliers are ours, computed from those ranges.
