Too funny! Major European Seltzer addict here. My wonderful husband engineer and frugality champion found 3 Sodastreams on CL, hacked them all a couple of years ago the same way and installed them in our 3 homes in the US and Europe – don’t ask! Frugal as he is we used the welding shop route right away except for the place in Europe which was a bankrupt food establishment where he found several old tanks which have been supplying endless amounts of Seltzer for 2 full summers now without an end in sight. Bubbly water is so much more popular over there and we would have to haul tanker loads home in glass bottles for the endless stream of visiting friends and family. Love your writing and ideas! Somewhat new to the blog so ready older posts now for inspiration and entertainment….
Before placing an order, you might want to know what it will cost to go this route. Typical prices for concentrate are $8 to $14 per quart, $7 to $10 for pints, and $3 to $4 for 4-ounce bottles. Shipping will be expensive—count on an additional 30% to 70%, depending on how much you order and the distance. Depending on these factors, flavoring costs are likely to range from $ to $ per liter. Obviously, at the high end you won't be saving much if any money over SodaStream's flavors, once you add in the cost of sweetener; but if you can buy a few pints or quarts at a time, the total cost (concentrate plus sweetener) will fall in the $-$ range. Most or all of the ingredients will also travel less than the SodaStream bottles, and what does travel will mass less, which all adds up to being better for the environment.
