Normally, no. Unless you have a special edition that we are unaware of, the only type of carbonated liquid that should be coming out of your SodaStream Sparkling Water Maker is just that – water. Although you can spring for a SodaStream like the SodaStream Fizzi, which has drop flavors of lime and orange to add to your drink, you’re taking a huge risk if you’re putting anything other than water in it. You can damage the Sparkling Water Maker and simply make a huge mess! Even though most of these products come with a warranty, like the SodaStream One Touch with its 2-year guarantee, this money-back guarantee will be invalidated if you carbonate any liquid other than water. You can add the drops or flavor but only after you’ve put the water through the fizzy process!
