Can you freeze soda?
The USDA prints no freezer time for soda. 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 soda has gone bad
Go by the date first: soda keeps 2–3 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 2 days to 3 days in the fridge once opened. What decides that is the food and not the shelf the source files it on: it 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 it past its 2 days to 3 days in the fridge once opened 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.
