Reusable bottle with soda-pop-style thread?
February 1, 2024 1:38 PM Subscribe
Where can I purchase an infinitely reusable bottle that has the same type of thread as a 1L or 2L bottle of soda--literally the exact same thread as a liter bottle of Coke you buy in a vending machine or convenience store?
I have a home made carbonation rig that uses a threaded attachment like this. For various reasons, I'd like to move away from using single-use recyclable water bottles from the grocery store, and on to something that is not manufactured to be disposable.
Here are my reasons.
1. I have some concern that if I reuse just a single Coke bottle from the store, that specific plastic starts to leach. I have read articles that argue for and against this position, but want to err on the side of caution.
2. I don't want to just throw away a store-bought Coke bottle every five uses in order to avoid the leaching.
3. I believe that if I buy a Special Bottle I will use the carbonation rig more often.
Apologies in advance if this is a Let Me Google That for You question, but I've already googled it for myself and not come up with anything.

The soda stream i was given has a rigid plastic reusable bottle and I was warned not to use glass as it can kaboom. The bottles are easy to source secondhand if you don’t want to buy from that company.

Response by poster: I don't believe the Soda Stream bottles are the proper thread, unfortunately. None that I've seen are.

Response by poster: Though I guess if there was a ball lock adapter for sale that fits SodaStreams that would be good, too. I will go looking for that.

Best answer: There are home carbonation adapters for Sodastream bottles. There are Sodastream-compatible bottles in various materials that probably include materials like stainless steel. That's the route I'd explore.

Best answer: I went looking for this a few years ago for the same reason and found absolutely nothing available

Best answer: I also went looking for this and came up with nothing. I was pretty sure it needed to be metal, as I was also uncomfortable with the idea of pressurizing a glass vessel sufficiently to carbonate the contents.
At the time it seemed like the best alternative would be to use vessels intended for beer, like the smaller kegs. I was looking at Cornelius kegs, but it seems like there are products aimed at the homebrew market as small as 1 or 2 gallons (Corny kegs are 5). Kegs are generally stainless steel, easy to open up for cleaning, are rebuildable/ have replaceable seals, and use widely available ball-lock fittings which are easy to tie into whatever existing CO2 tank and regulator setup you already have.

Best answer: I am trying to replace plastic bottles with used stainless kegs in my home setup, after a similarly fruitless search for drop-in bottle replacement. It’s been pricey and a learning curve.
Used kegs cost about 60$ and you’ll need two, one pressurizing over 5-10 days and another for serving. They will need to be cleaned thoroughly. The seals are hit or miss, even if the seller has “tested” them. I sprayed the seals down with dilute dish soap to check for leaks and replaced one set of seals.
The keg for serving needs to be pressurized at 5-7 psi, while the keg being carbonated needs to be at 30+ psi. I currently switch the co2 tank between the two kegs but am considering getting two regulators.
The run of tubing in cheap beer keg taps isn’t long enough for the pressure of seltzer. There is foaming in the line that kills the carbonization There is some calculation that will apparently get you the ideal length, but I just bought 12 feet of beverage tubing and that seems to work.
With the plastic bottle setup we would go through 10lbs of CO2 in 9-12 months, but we’re now going through 10lbs per 3 months. I’m not sure is this is the result of leaks or simply from pressurizing the kegs for serving.
Also, the stainless kegs are a pain to fill. I am considering piping in filtered water directly into the tanks, but this stainless tank setup is already about twice the cost of just my CO2 tank + regulator.
TL;DR let me know if someone finds a bottle replacement. Going to a restaurant-level seltzer system is a nuisance.

Response by poster: Okay. It looks like we simply all join in frustration and shake our fists at the sky. Thanks for the answers, folks, this has been helpful even if it hasn't resolved my question! It is always good to learn that your googling skills haven't gone hopelessly useless, and that others are finding your same dead ends.
