Where to Buy Carbon Dioxide (CO2) For SodaStream

As a SodaStream owner, I thought about the best way to minimise the cost associated with refills.
They run at about $20 per SodaStream bottle which is 400g of CO2. (which I go through in a month..)

There are kits you can buy (like this http://www.ibrew.com.au/products/freedom-one-soda-stream-ada... ) that can fit a standard
Australian gas bottle. Looking up BOC Gas I figured I could get 12Kg of CO2 for about $50. So I headed out
today and that's what I got. I also got a bit of a surprise; I found out, purely by chance when asking about a larger size,
that I will be charged 'rent' for the gas bottle. (And it wasn't cheap, at about $0.50 per day!)

Unfortunately for me, that means that the expecting 'savings' I would have got from say $240 per year with SodaStream Vs
$50 per year with BOC didn't quite materialise.

So I'm wondering, Where do OzBargainers get CO2 for cheap?
(I'm in Sydney BTW)

Thanks!

    You can also use dry ice as a supplement for gaseous CO2 provided by BOC. They sell These dry ice pellets which can be used.

    Check out this video on a good way to do it, it's a bit touchy because you need to weigh up the exact amount of dry ice you need, but it's a cheaper option.

      Does this actually work? On the face of it it seems ridiculous that it would because aren't those things filled with CO2 to a high pressure?

      •  

        Yeah it works but it really depends what lengths you want to go to to save money, it's a bit of a tough process but it will save you money in the long term

      •  

        However dry ice is a very touchy substance, too much and it will blow the cylinder possibly, so you need to be very careful with the amount you put in

    I can breathe into a bag for you. $19.99 per grocery bag + shipping.

    Soda King is doing a promo at the moment for a free cylinder exchange here

      Saw that, but the saving is very marginal, and I'd be stuck without a genuine bottle (deal breaker).

    If you're in it for the long term, you can buy a 2.6kg CO2 bottle normally used for homebrew for $199 filled, (or 6.8kg for $299) and a sodastream adapter ($25) and fill the sodastream gas bottles yourself. Refill of 2.6kg CO2 is about $25 at any homebrew store. Sounds like you'll use 5kg a year, so $225 in your first year (about the same as your current spend?) then will drop to $50 per year after. Lots of YouTube vids on refilling soda stream yourself, key is to use a scale so you know when to stop filling.

    You could even buy a keg and bypass the soda stream machine altogether - have 19L of soda water on tap. Then since you have the keg and tap already you could buy a cheap fermenter and start homebrewing. Maybe get a second fridge for chilling/serving the keg and another for fermenting the homebrew. Then end up filling the fridges with more kegs. Maybe upgrade to an electric BIAB system to brew more beer, and a stainless conical fermenter because it looks cool, then who knows maybe you move to a bigger house with more room to brew and build yourself a custom brew room. Maybe you end up spending thousands of dollars on a few hundred litres of mediocre beer, but hey at least it's a hobby you enjoy. And at least you've got cheap CO2 for soda water whenever you want.

      You don't think he should just skip all those steps and move straight to the 235 acre soda water bottling plant? It would save time!

    •  

      Thanks carnyturbo. This is what I actually after.
      Guess I should have gone to a Brewer instead of gas supplier.

  •  

    I just wait for discounts.

    Hi. I have the Freedom One adaptor hose as you mentioned. I bought my CO2 cylinder from the local beer brewing store. It lasts me about six months drinking soda water every day. They do bottle exchange for about $25.

    Hope that helps.

  •  

    Or you could buy cheap carbonated soft drinks from Aldi and when on special at colesworth

    •  

      The reason I use the Sodastream is they have a 'Zero' range which is no sugar, no artificial sweeteners.
      Don't need that sugar!

    I got a hose from Keg Kinghttp://kegking.com.au/co2-cylinders/freedomone-sodastream-adapter-hose-36inch.html and then went to my local brewing shop and purchased a 12 Kg bottle for $240.00, it cost $20.00 to exchange for a full one when needed. Yep cost a bit to setup but ongoing costs are minimal compared to using the sodastream bottles

    •  

      Thanks pjcook. That's kind of setup I was trying to achieve.
      Don't mind the initial outlay, so long as the refills are cheaper.

    •  

      Where do you get 12kg swaps for $20?

      My LHBS wants $50 for a 6kg MKOL bottle swap and won't touch Keg King bottles.

      •  

        Oops sorry, my bad, I was guessing the size of my bottle :) it is 4 KG. Still significantly cheaper than Sodastream Bottles

    I don't understand why you would do this

    •  

      After the initial outlay the cost per bottle is around 10 x cheaper, the Sodastream bottle is only 400 g and cost around $18.00 to exchange, wher I pay $20.00 to exchange my 4 KG bottle.
