We are going away for a few days over Christmas.

I would like to take some home brewed beer with me.

I can’t take my gas bottle and reg as I don’t want to travel with it in the car with the kids, and bottling is not an option (space and it’s a pita)

If I carbonate my beer as normal in the kegs, could I take a corny or two away and serve through a beer gun and use the 16g CO2 bulbs?

I’ve already got the beer gun, line and a mini regulator, so don’t want to have to get a soda stream and reg if a tenners worth of bulbs would do the trick.

How many bulbs am I looking at to serve a corny full of beer?


I’ve had a search, but most of the threads seem to be discussing using bulbs to carbonate.

Thanks
 
I don't know how many CO2 bulbs you would use, but it would work.

Other options are a soda stream cylinder or a 5l mini keg with the CO2 bulbs, which is what I use.

ive got a 5L mini keg, but there’ll be a few of us on it so want to take more than that.

How many bulbs do you use to dispense a 5L keg?

I might just buy a 10pack of bulbs and see how far they go
 
Should not take that many if your only dispensing already carbonated beer from the keg. If it slows down let the keg warm up slightly and get more co2 out of the beer and into the keg

Could you not pressurise your 5 ltr keg (empty) and use it as a small CO 2 tank?
Click to expand...
That would work I think.

Its got a 30PSI PRV, so could dispense the corny at about 6 psi- as long as the beer is already carbed.

In reality it would maybe be a touch higher as gas comes out of the beer?

I’ve ordered a pack of CO2 bulbs now so I’ll see how many I get through and report back 👍🏻

I usually use about 1 (16g) cannister per 5L. Set to around 12psi.

Same. By the time I’ve emptied a 5 litre mini keg, the gas is pretty much done. I would think it translates as the volume (liquid) is the same and the headspace in the keg as it empties that needed filling would be the same.

Just ordered 10 16g threaded food grade cylinders for £8odd delivered.

https://www.directcream.co.uk/mosa-co2-cartridges-16g-threaded-box-of-10

I’ll take a corny (or two) and see how long the gas lasts.

Time to get a brew on now 🍺

At 20°C, and atmospheric pressure of 1.01 bar, 1.8g of CO2 fills 1 litre, ie 1.8g/l or 8.9 litre per 16g bulb.

At higher pressures, each bulb gives proportionally less volume of gas.

eg. 10PSI =0.68 Atm, which is 10PSI above atmospheric, so actual pressure is 1.01 + 0.68 = 1.69 Atm
At 10PSI, 1 bulb gives 8.9 ÷ 1.69 = 5.3L of gas.
