How long doesBlack bean saucelast in the fridge once opened?

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.

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.

• Unopened · in the pantry18 months to 24 months
• Once opened · in the fridge3 months to 6 months

Turning the range into a date

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.

Is this window about safety or about taste?

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. Every figure assumes the food was sound when you stored it, that your refrigerator holds 40 °F or below and your freezer 0 °F or below, and that the package was handled normally.

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 FoodKeeper entry this page is built from prints storage times and nothing else, so anything past them here is USDA and FSIS guidance rather than a figure from the source. The whole rule, including the cases the source does not cover, is set out under what to do when the date has passed.

Is that a long time?

3 items in the Condiments, Sauces & Canned Goods list keep exactly as long as this item, 24 months, so they all share place 13 of 41 rather than being put in an order the data does not support.

Products the USDA rates in the same places

This is a common shape of record: 27 of the 466 products are rated in the same places, pantry from the day of purchase and refrigerator after opening, and 7 of the nine slots are left blank on all of them. Sorted by how close their windows are to this one, the nearest are Oyster sauce, Hoisin sauce and Chocolate syrup, and the rest of that group is what the list below draws on. Of the 8 shown, 2 keep longer than this one. The longest-keeping of them is Chocolate syrup at 2 years.

The rest of the Condiments, Sauces & Canned Goods shelf

The USDA puts this product on the Condiments, Sauces & Canned Goods shelf together with 40 others, and 12 of them keep longer outside the freezer. The shelf runs from Gravy at 5 years down to Aioli at 4 days. Nearest this product by window are Oyster sauce, Hoisin sauce and Dry gravy mixes, which is the order the list below is printed in. Across the whole of Condiments, Sauces & Canned Goods the same product ranks 13 of 41. The middle of the shelf is Pickles, at 1 year.

If it has to keep longer than this

If it has to keep longer than 24 months, Condiments, Sauces & Canned Goods offers 3 products that hold at least twice as long outside the freezer. The nearest step up is Gravy at 5 years against this one's 24 months, and the rest are Balsamic vinegar and Anchovies. A short list like this one is itself the finding: the category has few longer options. In the other direction, 16 entries in the category keep half as long or less, Cream sauces and Horseradish among them.

The record this page is built from

This page is built from a single FoodKeeper row, record 433 — the source’s own number for it, not a position — one of the 661 rows in the snapshot. That row fills 2 of the nine storage slots with a time, and the binding figure on it is printed by the source in months, which is the unit this page keeps rather than converting it to days. Every figure here comes from one fixed snapshot, USDA FoodKeeper, retrieved 1 September 2026, and is not refreshed page by page.

Where these numbers come from

Every range on this page is published by the USDA FoodKeeper and reproduced unchanged. The multipliers, the rankings, the percentages and the dates are ours, computed from those ranges. Where the source gives a span such as 3 to 5 weeks, comparisons use the upper figure, and the full span is always printed.

Rankings cover only the items the USDA gives a usable figure for, and identical ranges share a place rather than being ordered arbitrarily. Neighbors are chosen by nearest storage time within the same category, never alphabetically: two foods filed next to each other by name usually have nothing to do with each other. The freezer is excluded from ranking because it flattens almost everything.

Where the USDA lists several kinds under one name, they share one page here and every kind keeps its own windows: the source prints them as separate rows, and a page that merged them would be inventing a figure the source never published. Comparisons and the place in the category are computed for the kind the plain name means — the shell egg for eggs, the can for tuna — which is settled name by name rather than by the order the source lists its rows in, and the page names it. Where the plain name means no single kind, the page prints no single figure at all and lists the kinds instead.
