Let's be serious. Out of the entire google record, there's not one recorded case of a bottle exploding (that I can find) ... so is it that dangerous? Maybe the danger you speak of is regarding the C02 tank itself (admittedly a bomb if the neck ever failed); however, lots of people have oxygen tanks in their homes which is far more dangerous than C02 (I would think), and they're not scared. If anyone can find, on record, a case of a home carbonation system exploding the bottle (there's one case where the hose melted because it was too close to heat), then that would be interesting.

Perhaps a stupid question, but have you tried simply mixing frozen concentrate with fizzy water? Or for that matter, just mixing the jug juice half-and-half with fizzy water? I'd bet in a blind taste test, your mouth could not tell the difference after the first sip, between that and your injected fizzy. I know, it's an engineer thing- I wouldn't understand. Anybody remember how they did 'needle beer' during prohibition? -- aem sends...

And there's no danger in agitating it as long as you are not hitting the bottle with a sharp object. Just shake the bottle. Even just shake the top back and forth to make crashing waves, which increases surface area and CO2 absorbtion. Shaking the bottle decreases the pressure, as the CO2 disolves into the water. It does not increase the pressure because the pressure at the top is higher than the stabile pressure in the CO2 in solution. > I agree that your upside-down suggestion is better from the > standpoint of C02 contact with the liquid (no need to shake) ... but > it's just so much harder to accomplish that the right-side up with > agitation method seems safe for most of us. You could make a filler cap with a 5 micron air stone that reaches to the bottom of the bottle. Or, you can shake the bottle, or just be more patient. |
