Soda Syphon Instructions

With a soda siphon, or seltzer bottle, you can make carbonated water at home. Homemade carbonated water, which is also called sparkling water, soda or selzer, can be mixed with flavourings to make speciality drinks, often at a lower cost than store-bought sodas. Soda siphons are containers that use carbon dioxide chargers to impart carbonation into water. The containers then hold and dispense the carbonated water. Soda siphons, which are enjoying a minor resurgence in use, were popular during the 1920s and 30s.

Open the container and fill it with water. Use cold water for the best results. Reseal the container.

Snap or screw the carbon dioxide charger carefully into its housing. The housing is usually on the side of the head assembly, and may have a cap that must be removed before attaching the charger. If your siphon has a charger holder to assist with inserting the charger, use it according to the manufacturer's instructions. If it is a threaded housing, work slowly so you don't cross-thread the charger. Stop when you hear the sound of the gas being released.

Shake siphon vigorously for the amount of time recommended by the manufacturer, typically 10 to 15 seconds.

Remove and discard the charger, and replace the housing cap.

Dispense the carbonated water by depressing or pulling the trigger.

Store leftover carbonated water in the refrigerator.


Chargers are available through online merchants and at kitchen and gourmet supply retailers. One charger will carbonate one litre of water. Experiment with flavourings to create your own gourmet sodas. Drink your homemade sparkling water instead of higher-calorie beverages as part of a healthy diet.


Check to see that the container is fully discharged before opening it to refill. Make sure you buy the correct kind of chargers for your siphon; some snap on and some screw in.
