How long does Nectar last in the pantry?
Turning the range into a date
Nectar keeps 12–18 months sealed in the pantry. Counting 18 months forward from a date is not arithmetic anyone does reliably in their head. Give the field the day it went into storage.

The methods the USDA actually rates for this item
The USDA rates only 1 of its nine storage methods for this item, and the pantry from the day of purchase is what it rates. The other 8 slots are blank, and a blank is not a zero: it means no published figure, not that the method fails. On the same shelf it sits 7 of 22, between Diet powder mixes and drink mixes at 24 months and Lime juice at 18 months.

Can you freeze nectar?
The USDA prints no freezer time for nectar. 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 nectar has gone bad
Go by the date first: nectar keeps 12–18 months sealed in the pantry. Unexpected fizzing, cloudiness, floating strands or a sour smell mean it goes out. Once opened, keep it in the fridge at 40 °F or below. Keep the fridge at 40 °F or below and the freezer at 0 °F.

Is it still safe to eat, or just past its best?
The answer at the top of this page reads 12 months to 18 months in the pantry. The USDA rating this place at all is the USDA saying Nectar, papaya, mango, guava, or guavabana keeps there, so the figure rates how good it will be. 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 Nectar, papaya, mango, guava, or guavabana past its 12 months to 18 months in the pantry window. Past that the calendar stops deciding and the food itself does. Fizzing that should not be there, cloudiness, floating strands or a sour smell 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.

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.
