What opening the package actually costs
Opening the package is the decision that settles this page. Sealed, the item holds 12 months sealed in the pantry; once open it holds 2 days open in the fridge, the same food measured in days instead of months, a drop of 180 times. On the same shelf it sits 11 of 22, between Vegetable juice at 18 months and Yuzu juice at 12 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.

Can you freeze coconut water?
The USDA prints no freezer time for coconut water. 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 coconut water has gone bad
Go by the date first: coconut water keeps 1–2 days in the fridge once opened. 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 1 day to 2 days in the fridge once opened. Nothing here names the food: neither Coconut water 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 Coconut water past its 1 day to 2 days 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.
