Sodastream Economical Worth and Environmental Cost?

  • 9

Hi all. I like soda, but I rarely drink them (less than one per month). My question is not so much for me, but in general.

I like the customization concept of Sodastream and the related products, and many unique soda can be prepared. My question is about the economic aspect. If one were to only make standard soda (like coke and ginger ale), would it be cheaper to buy cases of Coca cola, or would it be cheaper to use Sodastream? What do you think?

The second question is about its environmental benefit. Sodasteam stated that it is more environmental to make soda at home than to buy it. What do you think?

"Using your own home carbonation system means:

Less packaging waste from cans and bottles.
Less pollution caused by transport of bottled beverages.

One SodaStream carbonator makes 60 or 110 liters, equivalent to 170 or 310 aluminum cans! When empty, the carbonator is refilled and reused, ready to make more fizzy and tasty soda whenever you want it."

  1. Just got one for a present. Have not opened it yet. Drink a lot of either Pellegrino or the W(t)F equivalent. Expect it to be less expensive and major thing no schlepping and carrying. Huge.

    1. For one soda a month you can buy a 12-pack for the year, recycle the carton and cans and be done with it. The Sodastream isn't meant for you.

      We can go through a couple of cases in a weekend during the summer (family and guests). Sodastream is a better option for us.

        For me, it probably does not make sense, but I am curious about its economic and environmental impact.

        <We can go through a couple of cases in a weekend during the summer (family and guests). Sodastream is a better option for us.>

        Did you notice money saving?

      2. I"ve had my soda stream for....seven or eight years I guess. I don't drink soda and never have. I am a sparkling water/seltzer water drinker. I haven't looked back since I bought mine (Penguin version). I don't think about the expense and have never calculated how much more i'm saving or spending.

        I do know I"m throwing a LOT less glass bottles in my recycle bin and that's not a bad thing. I like the convenience of the Soda Stream and the extra pantry and fridge space from not storing bottles and bottles of water.

        1. I wasn't much of a soda drinker either when we bought ours. I rarely drank store bought soda. I went through a period of buying soda water and syrups but I got tired of the soda water going flat because I didn't drink it fast enough once it was open. Plus I found that soda water in plastic bottles will go flat even when unopened if it sits long enough.

          The thing I like about soda stream is that I can use my own filtered water from home to make it. I choose the flavoring, and the syrups I use don't have the added salt or the high level of citric acid that many commercial soda does and it's made from sugar not HFCS. Plus I control the level of carbonation and how much syrup I want. A lot of commercial sodas are too carbonated and too sweet or too acid for my taste.

          Plus if I don't finish the bottle and it eventually goes flat I can just recarbonate it.

            That's news to me. I drink a lot of flavored seltzer and never had an unopened bottle go flat. In fact, once opened, a quarter of a bottle will still have some fizz 3 or 4 days later.

          2. For convenience, it can't be beat. DH and I go through 3 liters of fizzy water each day, and never run out since we got our Sodastream a few years ago. We don't use the syrups, but we were never big pop drinkers anyway.
            If you must abstain from alcoholic beverages due to health issues, the fizzy water is a great treat. Pour it into a pretty glass, add a splash of cranberry, lemon or lime juice, and you've got a cocktail.

            1. I love my SodaStream. I bought a model that uses the larger 130l cylinders and I make a liter or two a day. I don't use the prepared syrups but I have made cream soda syrup on the stove and used that a couple of times. Most SodaStream machines use no electricity. The pressure of the carbonator bottle powers the process. I believe there is a newer, pricier model that uses electricity. My costs are about .30 cents a liter as opposed to the $1.25 a liter Trader Joe's sells its sparkling water.

              1. Thank you people. I may go for a SodaStream. I don't think I will use it very often, but it seems like a useful tool. Now, I just have to figure which model to get. There are many models and to me, they all do the same thing. Afterall, it is all about pressurizing the liquid with the CO2 cylinder. So the heart of the system really the cylinder, and they all use the same cylinder.

                I will have to read up more about the different models.
