Keg Force Carbing Methods Illustrated

[bracconiere]

I would think you are ADDING CO2 dissolved to the weight of the liquid, thereby ADDING weight to the system.

no, i keep my co2 tank on a scale, and shake till it loses the right amount.....i think shaking a keg on the scale would kill the scale.....plus with the tank on the scale, while you're shaking the keg you can watch it go down 0.1oz at a time till ready.....

 

[balrog]

Ah. Of course.

 

[Bottoms_Up]

anyway, the scale is only $27....my fridge sucks, so it still takes a couple dyas to get cold enough to pour though....(but i just need more full kegs in there! )

It's hard to see the scale in the picture. Is it on a stand? What is the model name, etc.?

 

[bracconiere]

here it is...

i still need to get the weight of the tubing off of it though...got a tee and QD coming, and a lot of silcone tubing, that's long enough to where it should all be lying on the floor while i shake....

That separate reading panel is quite handy!

it stays on 24/7 if plugged into the wall also....i use it to detect leaks QUICK in my system.....why i got it, just had the off thought to use it for carbing too! and it works...

So no auto off with this scale? If so, I may have found a replacement for the Ultraship scale I've been using for the past few years.

not when it's plugged into the wall...it's on 24/7....that's how i keep an eye on my co2, just a casual glance here and there, make it hasn't mysteriously lost an ounce or two for now reason.....it does seem to drift up a bit with the room temp, but i've gotten used to that....

 

[balrog]

Drifting up when warm? Must be the natural buoyancy of the headspace--increased gas over liquid as temp goes up.

Yes, I said that facetiously. I don't need @doug293cz to jump on my idiocy.

Realized I over carbed my beer. Have spent about 45 minutes trying to fix it and have gone thru 4 pints of beer. Can't let beer go to waste, lol. Purged the beer, put it at serving pressure and just going to let it sit cause I still have 2 additional pints waiting to be drunk since the foam has gone by now. CHEERS!! Love this forum!

 

[bracconiere]

Love this forum!

the ineternet if you take it lightly, got me from 63% effec to 95%...and instantly carbed beer, and we'll see how the fan in the fridge gets it ready to drink in a day instead of two-three....

let's have a good carbed beer together!

Jesus, 95%?! I'd be happy if I didn't have mission control problems every time I kegged a beer! I'm currently kegging my latest brew, a Kveik Hazy IPA. I had it cold crashing for 3 days. Today, when I pulled it from the mini fridge, I immediately the blow off tube had slipped out of my star stan bottle. So I'm not sure how many days it's been exposed to oxygen :-( Figured I'd still keg it. I pulled an initial amount to pull sediment and took a sip and was not what I was expecting.

But life goes on, and there is plenty of brew to make. Cheers!

45m is too short to make significant change in dissolved CO unless you can bubble through an air stone from the bottom or shake keg roughly. It take time to dissolve and time to undissolve. Simply changing headspace pressure by venting everything, then letting it sit overnight will do a little, but if kept cold, CO2 will like to stay in cold solution. I guess my point is, you have to realize nothing happens instantly.

What ended up working was disconnecting everything and purging the keg. Then took the gas quick disconnect and put it on the fluid out post. Let the sucker bubble for some time, purged and repeated about 3 times. Reconnected everything as normal. Beer was normalized. Saw some Youtube video, dude said it was "degassing" or something or other. Worked!

I had to do this once and it accomplished the task - though it was on a REALLY FULL keg and the blow-out through the PRV was crazy. Had to unload the keezer to mop and wipe everything down.

If I ever have to do that again I'll run a line from the gas post into a bucket half filled with water and let it go nuts in there...

Cheers!

 

[bracconiere]

not the cleanest floor, i know.... but with the chair, and clamp...i got a perfect weight of 1.3oz's for both my kegs......no fluttering around while i shook them.....now to see if the fan in my fridge, gets them ready to drink in a day......

 

[bracconiere]

i gotta say it was sad, watching a ounce of co2 going up...just purging the kegs.....but at least now, my scale doesn't lose an ounce a day, waiting to gradually carb....

and anyone have a chart on carbonation, about how long it takes to dissolve into water? i know i got the right weight in them, and their not on pressure at the momment, but how long for a shaken can of beer to be ready to pour again after shaking?

 

[bracconiere]

well, i just burst carbed a alco-pop with 2.5oz's co2.....it went fast at first but, damn to get the thing to take more co2 at the end was a pain.....that last ounce was apainful tenth at a time minute.....

 

[bracconiere]

i put a tee on my gas line, and a second shut off, with about 10' of gas line with just a flare QD for gas on, idea curtesy of Pkrd.....

now my scale stays steady while shaking, and i'm taking a break to type this, because it takes WAY MORE then 30 seconds like i first thought!!

I apolagize for the messy floor, it comes and goes.....

edit: my god i need a automatic shaker to do this.......maybe rasberry pi wifi scale, or USB, and have it automatic.....

 

[bracconiere]

i gotta say, cold crashing makes burst carbing by weight so much easier! the kegs take the co2 SO MUCH quicker at 40f then 80f!

You're only discovering this now?

I cold crash in an upright freezer for 1 or 2 days, or shorter, depending on when I need that beer. Transfer the ice cold beer (~30F) to a keg and burst carbonate (rock & roll) right away, in under 10'.

Yes. Now look into spunding. It’s easier and saves even more time!

 

[Beenym88]

I used to do what I thought was the right way and it probably is I used a carb stone with the carb stone cornet keg lid. Then one time that lid broke so I used the shake method and will probably never go back. Using the carb stone I’d get the keg cold and it would take a few days to a week to carb up nicely. Now I transfer to the keg blast it to 30 psi and shake it for 5 minutes. Then I put it in my chest freezer and it’s good to go within 3 hours. I have no way to know if it’s exactly the right volume of CO2 but I’ve never had any foaming issues. I know this isn’t an exact science or the “right” way but if your like me and want a quick turn around it works like a charm.

 

[bracconiere]

You're only discovering this now?

i've only been watching the scale go down while "rockin & rollin" since september!

(and honestly i used to just drink my beer flat! i'd hook two kegs up at 8psi, start serving as soon as it was cold, and by the time i was done with my first keg the second would have some fizz. and by the end of the second keg, it start pouring a bit foamy, with my 1/4" line)

Hello

I would like to go for keg and have some questions.

1. Could i let keg to carbonate in fridge whitout co connected ? Or the co must be connected all the carbonation time ?

I would cool Beer in keg and then put the co in to the keg and then put it to fridge.

Thank you

 

[bracconiere]

depends on how you do it. burst, or slow and steady.

you will definetly need co2 hooked up to push it out of the keg though

 

[NSMikeD]

I recently learned how to refill my soda stream canisters with dry ice and I happen to have an adaptor to add standard threads so I will be adding a regulator so I can use my fermentation mini fridge to age/cold crash and carbonate my kegs while waiting to be tapped to the kegerator mini fridge each can only fit one keg,

in the past I purged the keg and naturally carbonated before tapping but often ended up over carbonated. I like the idea of letting the regulator dial things in.

 

[Vale71]

Hope you realize that by doing that you could exceed the maximum rated pressure of those canisters and cause them to blow up possibly causing bodily harm. Hopefully those things have a safety valve that will let go before the canister goes kaboom.

You're also getting a ton of oxygen in your beer but that's a secondary issue compared to personal safety.

Explain please?

 

[bracconiere]

dry ice is frozen liquid co2, which when it melts will have somewhere between 750-1000 psi......
