Sodastream Bottle Expiration

Sodastream bottles have expiration dates printed on the bottle. This has caused many to wonder whether or not it is actually necessary for them to have to replace Sodastream bottles.

Why Do SodaStream Bottles Expire?

Sodastream bottles expire because the structure of the bottle weakens over time. Because of the high pressure nature of the sparkling water that enters the bottle, it is very important that the bottle’s structural componenets are intact. By using bottles that are expired for drinking your Sodastream fizz water, you run the risk of the bottle exploding under stress.

The stress your Sodastream bottle may experience internally is due to the atmospheric pressure placed against the sides of the bottle. This pressure can cause the bottle to weaken over time.

To prevent pressure from mounting and eventually causing an explosion, the SodaStream soda maker company has labeled each bottle with an expiration date that is approximately four years beyond its manufacturing date. This means you can essentially own a SodaStream bottle for a few years before eventually having to replace it.

Why Do Sodastream Bottles Expire

How Long Does a SodaStream Plastic Bottle Last?

As previously mentioned, plastic SodaStream bottles expire about 4 years after they’re manufactured.

It is important to note here that we are talking specifically about plastic SodaStream bottles and not other kinds. There are SodaStream bottle types out there are made of different materials, but we’ll get to more about that in the next segment.

For now, just keep in mind that although carbonation may not seem like it would have such a stealthy effect on a plastic bottle, the truth of the matter is that a weakened bottle may not be able to handle the pressure of carbonation the way you think it will. Thus, it is important, though inconvenient, that you replace your SodaSteam bottles as soon as they expire to keep yourself and others free from a potential injury that could result from an exploding bottle.

Do Glass SodaStream Bottles Expire?

No, SodaStream glass bottles do not expire. Remember that plastic can weaken under the pressure of carbonation, especially when used with a SodaStream machine. However, this isn’t the case with SodaStream glass bottles. According to the website, SodaStream glass bottles can be used indefinitely and do not have to be replaced every four years.

Something you will need to look out for, however, are defects within the glass bottles themselves. For example, you won’t want to use a glass SodaStream bottle that has cracks or dents in it. If you do, the pressure of the bubbles and carbonation can indeed cause the bottles to explode. As you can probably imagine, the potential for injury when a glass bottle explodes compared to when a plastic bottle explodes is much greater.

Always exercise caution and inspect your glass bottle before it is filled with water.

Do SodaStream CO2 Bottles Expire?

As you may already know, there are two types of bottles (three if you consider the materials used) that can be used with a SodaStream machine. Besides either the glass or plastic bottle that you will fill with liquid beverages are the cylinder bottles that are filled with CO2.

CO2, or carbon dioxide, is needed to give fuel to your SodaStream machine. If you haven’t noticed already, the cylinders that the CO2 gas is housed in also have expiration dates. Similar to the reason that dates are printed on the drinking bottles, this expiry date signals when you should replace your SodaStream carbon dioxide bottle.

Ultimately, the reason that you have to replace your CO2 cylinder is for quality assurance. By replacing the bottle on or before its expiry, you ensure the quality of the CO2, and also, the safety of the cylinders.


How Long Does Soda Stream Gas Last?

SodaSteam gas lasts indefinitely. In other words, the gas used to form bubbles using the SodaStream machine never expires.

Remember, however, that the canisters that the gas is housed in do expire. It is important that you replace the cylinders and bottles by their expiration date so that you aren’t risking the cylinder exploding and causing injury.

Tips To Make SodaStream Bottles Last Longer

SodaStream bottles should always be replaced by their printed expiry date. Having said that, there are ways you can help extend the shelf life of your bottles so that they perform at optimal capacity until then.

Consider the following:

  • Keep your SodaStream bottles out of direct sunlight.
  • Clean your SodaStream bottles using mild detergent and cold or lukewarm water.
  • Avoid using heat on your bottle when you can.
  • Although SodaStream bottles are generally dishwasher safe, using them in a dishwasher may weaken the bottle’s structure faster than handwashing them in cool or lukewarm water.
  • Keep glass and plastic SodaStream bottles stored out of the way of pets and small children.
  • Place SodaStream bottles in a cool dark place where they aren’t exposed to heat and sunlight for optimal preservation.
  • Avoid rough handling of your SodaStream bottles, especially if the bottle is made of glass.

Remember, that despite following the steps mentioned, it is still your responsibility to replace the bottles and CO2 cylinders as soon as they expire. This will ensure the safety and integrity of these components of your SodaStream machine for a safe and enjoyable experience.

Why Do SodaStream Bottles Expire? It’s For Good Reason!

As you can see, SodaStream bottles do expire, but it is for a good reason. When you carbonate water the pressure from the bubbles push against the walls of whatever container is holding it. Thus, it is of top priority that your SodaStream plastic bottle stays in optimal shape in order to withstand the carbonated pressure of your SodaStream drink.

Though you can do many things to ensure the integrity of your SodaStream bottles, it is always advisable that you replace the bottles by their expiry date. Remember that the same is true even of the gas cylinders that come with your SodaStream machine. Be sure to watch for the expiry date printed on those as well.

I hope this helps!
