- How long do soft drinks last once opened? The precise answer depends to a large extent on storage conditions — keep opened soft drinks refrigerated and tightly closed.
How long do soft drinks last in the refrigerator once opened? Soft drinks that have been continuously refrigerated will keep at best quality for about 2 to 4 days after opening.
Are opened soft drinks safe to drink after the "expiration" date on the bottle? Yes, provided they are properly stored and the bottle or can is undamaged - commercially packaged soft drinks will typically carry a " Best By," "Best if Used By," "Best Before", or "Best When Used By" date but this is not a safety date, it is the manufacturer's estimate of how long the soft drinks will remain at peak quality.
How can you tell if opened soft drinks are bad or spoiled? After opening, commercially manufactured soft drinks will start to become flat and lose flavor; if the soft drinks develop an off odor, flavor or appearance they should be discarded.
Discard all soft drinks from cans or bottles that are leaking, rusting, bulging or severely dented.
