How long do Pine nuts last in the fridge?
Turning the range into a date
Pine nuts keep 3 months in the fridge. Counting 3 months forward from a date is not arithmetic anyone does reliably in their head. Give the field the day it went into storage.

The freezer helps less here than you would expect
The freezer buys less here than its reputation suggests: 3 times what the refrigerator gives, 3 months against 9 months, both still measured in months. For this item freezing is an extension rather than a different way of keeping it. On the same shelf it sits 65 of 70, between Cashew butter at 3 months and Potato chips at 2 months. Pine nut and nut are the same food in the source list.

What the USDA adds in words
The USDA attaches 1 handling note to this item, reproduced below word for word. It is not a storage time: it qualifies the figure above rather than replacing it. These are the source's own sentences, not ours, and they are the part of the FoodKeeper record that a table of durations cannot carry.
In the freezer. Store in a plastic bag within an airtight container.
Can you freeze pine nuts?
Yes. The USDA gives pine nuts 9 months in the freezer, and held at 0 °F food stays safe beyond that: the figure is about quality. Freeze it well wrapped while it is still well inside its fridge window: the freezer keeps quality, it does not restore it.
How to tell if pine nuts have gone bad
Go by the date first: pine nuts keep 3 months in the fridge. A sour or off smell, mold, slime or an odd color mean it goes out. The bacteria that make people sick change none of these, so past its window it goes out even if it seems fine. Never taste to test.

Is it still safe to eat, or just past its best?
The answer at the top of this page reads 3 months in the fridge. What decides that is the food and not the shelf the source files it on: Pine nuts is acid, dry, sweet, alcoholic or pure fat. Past it, whether it has gone bad is yours to judge by look and smell: this window rates quality, not the day it turns hazardous.
It is past the date. Now what?
Say the calculator above puts Pine nuts past its 3 months in the fridge window. Past that the calendar stops deciding and the food itself does. A rancid, paint-like smell in a nut, an oil or a seed, mold around the neck of a bottle, or a swollen can mean it goes out whatever the date says.
The whole rule, including the cases the source does not cover, is set out under what to do when the date has passed.
Two places, and one of them is the wrong one
The USDA rates two places for Pine nuts in one state and they disagree: 3 months in the fridge against 2 weeks to 3 weeks in the pantry. This page answers with the refrigerator, the longer of the two. Both figures are the USDA's own, so this is a choice of where to put the food rather than a disagreement about how long it keeps.

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.
