homemade carbonation solution for hard seltzer?

[Bobby_M]

Assuming that the OP wants to water down his cocktails. I don't know too many people who add seltzer to martinis.

I missed that post when he wrote "martinis" but that renders everything moot. You can't carbonate a martini as the alcohol content is too high.

Yeah, so I guess the best one could do is to make VERY highly carbonated water and add just a splash to your drink. Like maybe 8 volumes?

I'm not sure how many volumes will actually stay in water once the head pressure is released. The closer to freezing you can get it the better.

Carbonation cap. Fits PET soda bottles. And this version of the charger comes with a ball lock quick disconnect (QD), which you will also need. Can probably find better prices.

i think carbonation cap + PET soda bottle + Co2 tank and regulator is the easiest option for very small volume cocktail,recipes. can do 1L or 2L sizes in soda bottles. After carbonation can be kept in refrigerator and pour as needed.

I'm still not completely sure that I understand exactly what the OP is trying to do. The thread title says hard seltzer but post #7 says martinis.

8 volumes at say 36°F needs around 65 psi to get there. Whatcha gonna store that in?

I've read that PET soda bottles can handle 10 volumes at 68F, and that a 2 liter bottle of Coke has around 50 psi at room temp (supposedly at 4.5 volumes). They don't rupture until well over 100 psi (again, if you can believe what you read on the internet).

Yeah, I read the title as seltzer so I'm assuming making seltzer was the goal but then in the thread the word "cocktail" came up, which can also be some mixture of seltzer, fruit juice and other things that can be carbonated. Then the word "martini" was used, which is USUALLY just spirits that ends up being about 40% ABV (no carbonation gonna happen there). I guess the conclusion is that the OP doesn't know what time of day it is or has consumed too many Martini Seltzer Cocktails.

Getting the volumes and keeping the volumes are very different. Once the cap is removed and the first bubble forms, you've got a nucleation point chain reaction.

Second option sounds like a not-bad idea given that it's Friday afternoon.

Understood. You would need some kind of rig that lets you dispense without removing the cap. Threw this together with a few things I happened to have lying around.



And before anyone asks - I have absolutely no intention of testing this at 100 psi.

Edit - the pictured tap is only rated for 20 psi, so that's at least one thing that would have to change; might want to add a carbonation stone too, and there may not be room to snake another piece of tubing thru the cap.

You can't? I was reading online that it was doable.
