Ditch your overpriced Sodastream cannisters in favor of refillable CO2 tanks

You can do this by putting the gazpacho (and anything else permeable and edible) in a closed-lidded cooler with dry ice overnight.

Fizzy apples are weird.

On the ā€œonly we can refill the tanksā€ issue, there’s no reason to be sympathetic. It’s impossible for me to refill a CO2 tank myself – I don’t have a supply of CO2 – but I can take a standard 5-pound CO2 tank to many places which will fill it with no problems. Nobody is going to blame Coke if the CO2 tank powering their soda fountain explodes in a restaurant; it’s clearly not their fault.

Soda Stream could have used industry-standard connectors so that any gas supplier could refill the bottles with as much safety as anyone else. But they didn’t. They used non-standard connectors so that only they could refill it. It also means that if it does blow up or otherwise fail, Soda Stream are the only ones I can sue.

I found two dozen or so latents, but not the one I’m thinking of. It was awarded in the 90’s to a guy working for Guinness, then later became the chief beer scientist for Anheuser. And I can’t remember his name, the book is 600 miles away, but I can remember his face.

Here’s an interesting table that shows what kind of stuff could be in the non-food-safe CO2, and the common sources for those contaminants. From an article about the International Society of Beverage Technologists guidelines.

Found through a Serious Eats article describing this same kind of project, he did extra digging to give some tips that could be useful to ease your mind about where you source from.

I’ve found that if you keep salsa or marinara sauce around long enough, it will turn fizzy. No need for a CO2 supply.

On a similar note, any cream cheese can be garden herb cream cheese, when aged well.

CO2 is much different than compressed air. It is virtually impossible to blow up a CO2 tank filling it from a larger source unless you use a pump of some time. Even then there are safety measure (see below).

Filling small tanks, at least in paintball, you would take one of the larger welders type tanks, and basically siphon the liquid CO2 into the other tank. CO2 is weird compared to nitrogen or oxygen, as it likes to form a liquid when it gets cold and compressed. On hot days you would have to fill and drain the smaller tank a couple times to chill it to get a good fill. But when you fill a tank you generally fill by WEIGHT, like a 20oz bottle. Unlike an air tank which is filled by volume at a max pressure, say 68cui at 4500psi

Also what is weird about CO2, is it’s pressure is affected by temperature waaaay more than say compressed air. So if you leave a tank out in the sun on a good day, especially full, it is going to exceed the safe pressure range (which is ~1800psi IIRC). Fortunately, tanks have what is known as a burst disk. Basically a slim piece of metal that is made to burst when the pressure gets too high, venting the CO2.

Of course tanks can fail from damage, and the vent mechanism could be damaged or tampered with (I read about a guy last year killing him self messing with, I think, paintball tanks for his soda stream). But if you don’t bypass the basic safety features, CO2 tanks are much safer than say compressed air tanks.

I’ve bought a ā€œfreshā€ sliced fruit bowl once from a supermarket where the fruit fizzed when I bit in. Rather put me off of any of those kinds of prepackaged things for a while afterwards…

Supermarket pruno?

I created an account just to respond to this!

It’s not ā€œstainlessā€ like ā€œpainlessā€ (devoid of stain/pain).

It’s ā€œstainlessā€ like ā€œstain-lessā€ (it’s not free of corrosion, just less likely to. It depends on the grade of stainless.) Salt can indeed cause troubles!

Also, emphasizing the ā€œlessā€ when you pronounce it (like ā€œstain less steelā€) is a great way to weird people out.

The 300-series stainless steel (typically 304, can be 316) doesn’t cope well with chlorides, and will suffer pitting quite happily. For chloride duty, you may like another alloy - maybe a 400-series steel, or Alloy 20, or some sort of bronze (aluminium bronze?) or titanium…

Also, another thing to be wary with stainless steel, it relies on oxidizing environment to maintain the passivation layer of oxides. If it keeps getting removed (e.g. erosion by flowing fluid), or if it cannot form/reform (in reducing environments), corrosion will merrily progress.

I just read in some forensic engineering book a mention of some family that left a piece of meat on a stainless counter before leaving for holidays. When they returned, and scraped off the remaining mess, they found the stainless sheet pitted through under the meat.

Also the summary talks of air when it should mean CO2. It seems to confuse the two terms.

Well it depends on the temperature and pressure. Liquid nitrogen is no big deal on Pluto for example.

Well, ANY gas can get liquid if it gets cold enough. C02 has a relatively low threshold. And it likes to go from solid to gas, skipping liquid, if possible.

Yup.

I tried doing coffee because I wanted to replicate Manhattan Special (my drug of choice when I lived in NYC). This proved to be a very bad idea. When I tried as much carbonation as I would use for water, removing the bottle produced a near explosion which got coffee in about a 5 meter radius and sent the bottle flying hitting me in the side of the head. Trying with less carbonation just ended up tasting not good at all.

If you are in the US, find a vendor to ship you Manhattan Special.

Because when Jordan annexed Judea & Samaria, the West didnt complain but when the Jews live there that somehow becomes a problem.

Just don’t drop them on a hard floor. A friend’s leg to this day looks like a wolverine gnawed on it, due to a glass seltzer bottle explosion many years ago.

I’ve never understood the point of SodaStream. COā‚‚ spritzer bottles have been around for ages, and even the little whipit-sized cartridges are cheaper than SodaStream’s oddball proprietary cylinders. You can find adapters to charge them from an external tank too.

And they look classier. Can you imagine William Powell using some plastic countertop gadget to make cocktails?
