How long doesBacon greaselast in the fridge?
The freezer helps less here than you would expect
The freezer buys less here than its reputation suggests: 2 times what the refrigerator gives, 6 months against 12 months, both still measured in months. For this item freezing is an extension rather than a different way of keeping it.
Every storage figure the USDA publishes for this item
The USDA rates this item cold or frozen and never at room temperature: no pantry figure exists for it, as for 222 of the 466 foods in the data that get no pantry time at all.
- In the freezer12 months
- In the fridge6 months
Turning the range into a date
Counting 6 months forward from a date is not arithmetic anyone does reliably in their head. Give the field the day it went into storage.

- In the fridgeUse by6 months after the day you stored it
Is this window about safety or about taste?
The answer at the top of this page reads 6 months in the fridge. What decides that is the food and not the shelf the source files it on: Bacon grease is rendered fat with no water in it. Past it, judge it by look and smell: this window rates how good the food will be, not the day it becomes a hazard.
Held at 0 °F food stays safe for as long as it stays frozen, which is why a freezer figure counts as quality on this site whatever the food is. 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 Bacon grease past its 6 months in the fridge window. Past that the calendar stops deciding and the food itself does. A jar or can that is bulging, leaking or rusted goes out unopened, and so does an opened one with mold at the rim or a sour, fizzing smell.
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?
5 items in the Condiments, Sauces & Canned Goods list keep exactly as long as this item, 6 months, so they all share place 29 of 41 rather than being put in an order the data does not support.
Items that behave the same way
All 4 of the 6 items nearest this item keep exactly as long as it does, 6 months, so the ranking around it is a tie rather than an order.
Products the USDA rates in the same places
This is a common shape of record: 33 of the 466 products are rated in the same places, freezer and refrigerator, 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 Prosciutto, Frying oil and Cheese Curds, and the rest of that group is what the list below draws on. Of the ones shown, none keeps longer than this one does. The longest-keeping of them is Prosciutto at 3 months.
- Prosciutto2 months in the fridge
- Frying oil1 month in the fridge
- Cheese Curds2 weeks in the fridge
- Pineapple5 days in the fridge
- Zucchini1 week in the fridge
- Cooked rice4 days in the fridge
- Apple juice6 days in the fridge
- Carrot juice6 days in the fridge
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 28 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 Mayonnaise, Pesto and Hot sauce, which is the order the list below is printed in. Across the whole of Condiments, Sauces & Canned Goods the same product ranks 29 of 41. The middle of the shelf is Marinades, at 1 year.

If it has to keep longer than this
If it has to keep longer than 6 months, the Condiments, Sauces & Canned Goods aisle gives 28 products that hold at least twice as long outside the freezer. The smallest step up is Cream sauces at 12 months against this one's 6 months; after it come Horseradish, Salad dressings and Barbecue sauce. They are printed below in the order the step gets bigger, not alphabetically. In the other direction, 8 entries in the category keep half as long or less, Duck fat and Frying oil among them.

The record this page is built from
This page is built from a single FoodKeeper row, record 525 — 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.
