How Long Does Club Soda Stay Fresh?
Keep the fizz and flavor in your favorite sparkling beverage.
Club soda stays fresh for up to 1 year in the refrigerator if the seal remains intact.
Club soda is a staple for many who enjoy a crisp, carbonated beverage without added flavors or juices. Because it is primarily water and carbon dioxide, its shelf life is generally determined by the integrity of its packaging rather than biological spoilage like mold or rot. However, once opened, the carbonation begins to escape rapidly into the atmosphere. Keeping your club soda in a cold environment helps preserve the bubbles for as long as possible while maintaining the quality of the liquid inside. Proper storage ensures that every sip remains refreshing and bubbly, whether you are mixing it into a mocktail or enjoying it plain on a hot afternoon.
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 doesn't become toxic over time, it will eventually lose its carbonation and flavor.
Should I store club soda in the refrigerator?
Yes, refrigeration is the best way to maintain freshness. Keeping it chilled helps preserve the carbonation and ensures a crisp taste for as long as possible.
Can I drink flat club soda?
Sage's Verdict: Yes, it is safe to drink, but it will lack the signature fizz and crisp mouthfeel of fresh soda.
Can I freeze club soda?
Freezing is not recommended. Freezing causes the carbonation to separate and can result in a different texture and taste once thawed.
Keep that cap tight and your fridge cold to keep those bubbles dancing as long as possible!
