You can't charge your beer to soda carbonation levels - soda has something like 3X the carbonation of beer. If you do charge beer like soda then you will always have a mess. Problem is I don't believe that SodaStream has an adjustable carbonation level, at least not one that will go low enough for beer.
Instead, follow the link I sent to you but set your CO2 regulator to 15 PSI instead of 40 PSI.
Why not?
My Soda Steam is carbs to 30 PSI, IIRC. Carb warm beer at 30 PSI for 24 hours and you're still undercarbed. 40 PSI certainly isn't outside of the realm of force carbing, especially at fermentation temperatures.
I force carb my beer at 3x serving pressure (up to 52 PSI so far) for 24 hours at serving temperature and it's always just about spot on. Be sure to bleed off the excess pressure after 24 hours.
Here, look at this force carb chart. Let's pretend it's 65F. 30 PSI indefinitely is still only 2.57 volumes of CO2. That's well within the acceptable range for many styles, and even undercarbed for many others.
Extrapolate 70F at 40 PSI. I'll wait here while you do it........ 2.77 volumes. Look at that, perfectly carbed for many styles.
So, what method did you use? I would be nice to know as I really don't want a messy trial. I think it would be really tough to keep it from over fizzing and making a foamy mess when I went to release the air.
I know there's like 10 Soda Steam models, but I have the basic $80 one they sell at Staples and whatnot. You tilt the adapter out, screw on the bottle, then carb, tilt the adapter back out (bleeds off all pressure), then unscrew.
Bleed slowly if you carbed anything other than plain, cold water, or all of the CO2 will fall out of suspension and make a big mess.
yeah, I'm calling BS on this
EVERYTHING I've ever read on doing this, 100s of posts and threads; if you add ANYTHING else before injecting the CO2 results in a huge mess.
how exactly did you figure it out? please give details
or, better yet, video or it's BS
Call BS. That makes me want to go prove that this can work. Gotta find e some room temperature beer to prove it with now...
I routinely carbonate Crystal Light, Country Time Lemonade, Kool-Aid, etc. Or am I imagining this?
