CO2 questions

According to the graph 15%. Not sure where that data came from or if it's accurate though. From my experience it is not.

Agreed..this graph doesn't help much. I did find a post where the author stated that one way to tell you're empty is when the gauge reads zero...pay no attention to in the red. So if I have a full one on stand-by, I can immediately swap out.

I rather look at the effect temp has on the gas vs looking at that chart. If your tank is full and reads 1,000 at 80F, then you'd expect that same volume of gas to read 500 at 33F or roughly half of what it was reading before you chilled the tank.. The volume is still exactly the same but the effect of the temp makes it appear the chilled tank is in the red zone.

That is good advice!

Beer on CO2 update.

So my 2---5 gallon corny's have been on 12psi @ 39 degrees since this past Saturday. I did a taste test yesterday at 5 pm and perfect carbonation/taste/clearness That's less than 4 days. From all I've been reading, I thought it was going to take 7-10 days or more. What gives? Luck?

And the student becomes the teacher. What the hell did you do? I just poured a pint of my Kolsch which has been sitting under pressure for 2 weeks and it's only about half way there. Time to drop the temp and kick up the psi I guess.

I'm not an expert but everything I've heard says growlers are not made to hold the pressure of naturally carbed beer. It may have worked so far but I believe you are playing with very dangerous fire.

Just that. 12 psi @ 37-39 degrees. I say 37 now cause that's what I'm seeing on my thermometer. I kind of toggle the tap when pouring to get some head but the carbonation is definitely there.

As long as I fill up the the bottom of the neck on growler and use 5 oz per 5 gallons. I've never had issues. Roughly 40 growlers per 20 gallons X 6-7 brews = 240 to 280 growlers total. No explosions.
