Newbie - bottle pressure ?
Posted: Wednesday Dec 23, 2009 2:47 pm
Hi everyone,
Chris in WA here,
love this forum, heaps of info
I just started brewing again after a few years being too busy, and am now hanging out for some real beer again.
I'm just brewing the standard 1 can 1 kilo stuff with malt etc for now.
I was wondering if anyone could tell me approximately what pressure would be in a stubbie / bottle when its ready to drink.
I have a hairbrain sceme (that most likely wont work, but is worth a try) for carbonating bottles without adding sugar when the bottle is capped, but to get it half right I need to know what pressure the bottles would be at when ready to drink.
I would assume 1 to 2 psi would be about it ?
If anyone knows it would save me a lot of pain experimenting.
Basically I want to make a spring loaded plunger / capper with a piston which allows the Co2 in from a sodastream cylinder, and you just pull down slightly, allowing the gas in, then wait about 5 seconds while it purges, then pull down and cap it.
The stroke of the piston would also compress the gas into the bottle, then it at the end of the stroke the cap is pressed on.
If this whacky idea works it would eliminate the sediment in the bottles.
Plus you could later quite easily store and use the Co2 from your brew to put into the bottles maybe.
Please tell me why this wont work if you have any reasons.
Anyway, have a safe and happy xmas break everyone,
Happy Brewing
