Co2 cylinder question?

If you can get used ones at a good price they are worth picking up. Just look for ones that have been pressure tested. Do a good job of cleaning them and replace all of the o-rings.

thanks, ill probably end up bottling these first few batches anyway. i should taste my final product before i get to carried away with buying keg and more costly equipment. i might check out a local home brew store so i can actually see what im buy first, rather than just rolling the dice with online ordering.

I have about 14 used kegs that I got from a friend that I am sure bought them used. I had a leak at a gasket with one of them, but he sent along a bunch of spare parts and gaskets. Unless they have a hole in the stainless, not much can go wrong that cannot be fixed.

thanks 560

Uh, be very careful. Some of these big tanks have the dip tube the runs to the bottom and brings up the liquid co2 (I think). I know the guy that uses the type of tank you describe to refill mine by going to the bottom liquid. I am guessing the liquid would not be good for pushing and carbing beer.

i dont think liquid would be good, quite dangerous i agree…all compressed gas is in cylinders is in liquid form of course, but no it comes out as gas, the bottles youre refering to should have separate valve sytems for releasing either gas or liquid, to the best of my knowledge. thanks for looking out.

@Baratone Brewer

Agreed. You do not want to use it if it is a siphon tank. The liquid can create a very dangerous situation and ruin equipment.

[quote=“a10t2”]The benefit of oxygenating over aerating is that it’s faster, and that you can reach higher DO levels, which may be desirable for lagers and/or big beers. The risk that comes with using oxygen is that without a DO meter you can never be sure exactly how much you’ve added, and it is possible to over-oxygenate and do damage. At a minimum, you’ll need a flow rate meter so that you can at least make an educated guess as to how much O2 is in the wort.

Personally, I feel like the saturation levels reached with aeration (9 ppm for ales, 12 ppm for lagers) are sufficient, and that leaving an air pump plugged in for 15-20 minutes isn’t a major inconvenience.[/quote]

thanks for that information, sounds to me like i will just stick to aerating by hand for now.

i dont know what the disposable o2 bottles from duxx are,but cool, let me know how it works out.

I guess I could have worded that better. Duxx is a member of the forum, and the disposable bottles are the kind you get at a hardware store. Same size as the disposable propane. I tried the wine degasser, aquarium pump, and shaking the hell out of it. Might as well try oxygen too. I can’t say that I’ve noticed a big difference in any method.

oh. i see. well thats where all the fun in this is right? experimenting?
