How Long Does Club Soda Stay Fresh?
How long does club soda stay fresh?
Club soda stays fresh for up to 1 year in the refrigerator if the seal remains intact.
Club soda is a versatile, carbonated beverage primarily composed of water and carbon dioxide. Because it lacks sugars, juices, or dairy, its shelf life is determined by packaging integrity rather than biological spoilage like mold or rot. The primary concern with club soda is the loss of carbonation; once the seal is broken, gas escapes into the atmosphere, leading to a flat taste. Storing your club soda in a cold environment helps maintain the pressure required for those crisp bubbles and preserves the liquid's quality. Whether you are using it as a mixer for cocktails or enjoying it plain, proper storage ensures the beverage remains refreshing.
Heads up: shelf-life ranges are estimates based on home storage. We make no guarantee of accuracy. When unsure, throw it out.

Common questions
Does club soda expire?
Club soda stays fresh for up to 1 year in the refrigerator as long as the seal remains intact. While it does not become toxic, it will lose its carbonation and flavor over time.
Should I store club soda in the refrigerator?
Yes, refrigeration is the best way to maintain freshness. Keeping the liquid chilled helps preserve carbonation levels and ensures a crisp taste.
Can I drink flat club soda?
Yes, drinking flat club soda is safe, but it will lack the signature fizz and refreshing mouthfeel of fresh soda.
Can I freeze club soda?
Freezing is not recommended. The freezing process causes carbonation to separate, which can result in an unpleasant texture and taste once thawed.
Keep that cap tight and your fridge cold to keep those bubbles dancing as long as possible!
