How long does club soda last in the refrigerator once opened? Club soda that has been continuously refrigerated will keep at best quality for about 2 to 4 days after opening.
Is opened club soda safe to drink after the "expiration" date on the bottle? Yes, provided it is properly stored and the bottle is undamaged - commercially packaged club soda 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 club soda will remain at peak quality.
How can you tell if opened club soda is bad or spoiled? After opening, commercially manufactured club soda will start to become flat and lose flavor; if the club soda develops an off odor, flavor or appearance it should be discarded.
Discard all club soda from cans or bottles that are leaking, rusting, bulging or severely dented.
