Expiration & Storage Tips
When does club soda expire?
Unopened club soda can be stored indefinitely, as the expiry dates on the package usually refer to quality not safety - so you may notice a decrease in fizziness past this date but it remains safe to consume. Once opened, however, club soda should be consumed within 2-3 days, as it rapidly loses its signature fizz. If the soda is homemade, it'll have a shorter lifespan and should be consumed within 1-2 days, and freezing is not usually recommended as the expansion of the liquid can cause the container to rupture.
How do you tell if club soda is bad?
Club soda does lose its fizz over time, and this doesn't necessarily mean it's bad. However, a change in smell or a cloudy appearance are good indicators that the club soda should not be consumed. These are both signs of contamination or reaction with the container, which can occur if it's been stored improperly or for too long after being opened.
Tips for storing club soda to extend shelf life
• Store unopened club soda in a cool, dark place, like a pantry or cupboard. Temperature fluctuations can affect the carbonation levels.
• Once opened, put the club soda in the fridge to help slow the loss of carbonation.
• Always replace the cap tightly after using, this will also help maintain the fizziness.
• Avoid storing club soda (or any carbonated beverage) in plastic for too long, as it can impact taste and potentially leech chemicals into the drink.
