Use the SodaStream Spirit One Touch to make light sparkling, medium sparkling, or more intense sparkling water with 1 press of the button. Firstly, fill the included drinking bottle with water. Press one of the 3 buttons for different levels of sparkling water, and the sparkling water maker automatically adds the right amount of carbon dioxide. This way, you can easily transform tap water into your favorite sparkling beverage. Do you want to add a flavor to your sparkling water? Do this after you've added the carbon dioxide to the water. When your sparkling water is ready, simply put the cap on the bottle and easily take it with you on the go.
